xsd:string range in iCal ontology

2009-10-21T07:52:03Z

Hey folks,

In the iCal ontology [1], you attach range 'xsd:string' to many
properties, such as 'ical:description' and 'ical:comment'. Although the
range is suitable for properties such as 'ical:tzname', etc., such a
range is not suitable for properties with prose text values as it
precludes the usage of language tags. A literal with a language tag
cannot be a member of 'xsd:string' (see [2] for discussion), and many
people use properties such as 'ical:description' with language tags.

Perhaps the easiest and best solution would be to remove the
'xsd:string' range constraint from such prose-text properties.

Cheers,
Aidan

[Fwd: [VCARDDAV] The TZ registry]

An approach to TZ namespaces, from the vCard list...

Hi folks,
One thing I forgot to mention during the discussion today: CalConnect was
planning on a registry of timezone names but we wanted to have these as
urns, probably urn:tzid:XXX etc. I think this is a reasonable use of urns
and provides a way to unambiguously indicate the scope of identifiers we
are using.

So if we choose to adopt this approach, the TZ document would need to
register the new urn scheme, and then define the tzid registry where one of
the attributes of the registry is the timezone's urn identifier.

Re: VCal namespace (take the year out?)

I would be happy with a new namespace as well... but then we have to
stick to it. I agree with Section 7 of the document: having to choose
between two evils, I would rather have a changing semantics than a
changing URI. And I think this is why these days people don't encode
creation dates in URIs anymore...

Cheers,
Peter

I suggest
http://www.w3.org/ns/cal
backed by a W3C XG (which just needs 3 W3C member orgs to start).

I think the test suite is critical too. Note the test suite
(and surrounding toolset) currently uses the icaltzd namespace.

Actually, I guess Peter's proposal is not a migration of two designs,
but to clarify the namespace URI for the current design, i.e.
...2002/12/cal# and ...2002/12/cal/icaltzd# use the same date-time
model.

I still keep some amount of documents with original namespace, but I
use separate scripts and stylesheets for them. Some simple rules will
help to migrate them into new model.

btw, I also write a chapter that introduces RDF vcard (2006 version),
whose namespace is another headache...

Ah, I'm glad this was a misunderstanding :)

After this migration, do you have any new insights into the tradeoffs
between the two designs? If you're aware of problems, it seems that we
still could address them since none of this has massive adoption yet.

Oops -- after excluding microformat-producing sites (using Sindice's "-
domain:www.xyz.com" syntax), only some 20 documents are left using the
icaltzd namespace. So, both namespaces are equally unpopular.

Not sure what we should do.

Re: VCal namespace

Oops, sorry, I thought the opposite:

(i.e. I misunderstood that you proposed to use ...2002/12/cal#,
instead of ...2002/12/cal/icaltzd#).

As Danbri mentioned, I've used another original URI
(...2002/12/cal/ical#) for a long (!) time, and recently moved to
...2002/12/cal/icaltzd#, so upset by one more change...

Some problems may still remain, but in my case, it is welcome to make
the namespace URI clear and stable.

It's definitely good to ground this in stats. Can you run a different
query that distinguishes the microformat-converted piece from the rest?

Last time I was at DERI Galway I had some discussions w/ SWSE folks and
we made a prototype, see sample Google doc (w/ flash vizualisation) at
http://spreadsheets.google.com/ccc?key=phsHybBDW1ySxupr8xfL4Zw&hl=en ...
which tries to take into account the spread of vocabulary use across
sites, as well as the raw number of documents / triples. In this case
it's clear such information is critical to decision making: 139k
documents using the icaltzd sounds like a huge endorsement for that
work, ... yet if it all mostly from 5 lines of easily-changed Perl
running on one system, rather than documents out there in the wild.

Here are some related Google Code Search results:

http://www.google.com/codesearch?q=%22http%3A%2F%2Fwww.w3.org%2F2002%2F12%2Fcal%2Ficaltzd%23%22&hl=en&btnG=Search+Code

ie. "http://www.w3.org/2002/12/cal/icaltzd#" ... 142 hits.

Contrasting with only 10 for "http://www.w3.org/2002/12/cal#" .

While 142 is > 10, neither number seems to indicate massively widespread
adoption.

For comparisons:

"http://www.w3.org/1999/02/22-rdf-syntax-ns#" - ~72500
"http://purl.org/dc/elements/1.1/" - ~51500
"http://www.w3.org/2000/01/rdf-schema#" - ~15000
"http://xmlns.com/foaf/0.1/" - ~6000
"http://www.w3.org/2002/07/owl#" - ~6000
"http://purl.org/dc/elements/1.0/" - ~1000
"http://purl.org/dc/terms/" - ~3000
"http://xmlns.com/wordnet/1.6/" - 545
"http://xmlns.com/wot/0.1/" - 244
"http://www.w3.org/2003/06/sw-vocab-status/ns#" - 160

However "http://rdfs.org/sioc/ns#" only finds 172, which suprises me
given the amount of activity around SIOC and hence makes me cautious of
this approach. Still, the more evidence we can gather the better, and I
think such searches (maybe with a bit of refinement) potentially very
illuminating. It's also worth stressing that these crude metrics would
count equally a line of code in some abandoned test script, versus a
line in a hugely adopted codebase (eg. drupal, livejournal). So clicking
through those results and skimming the detail is probably also important.

Dan

Exactly: given that at the scale we operate we can not afford complex
reasoning to figure out the relationship between two ontologies (even
if they are 99% same and they differ in a single axiom). So without an
agreement on URIs there will be no interoperability.

Good news is: it's not too late... we are still a small group and there
is room to change things. We can change on our side, Sindice can change
on their side... but the window of opportunity is closing. So the
question: if the Semantic Web is to start today, what namespace should
people use to represent hCalendar and other calendar information in RDF?

Cheers,
Peter

Since my post in May 2007, the Nepomuk Calendar Ontology has been posted
on a server where it is available at its proper namespace. Some
decisions we made come from the Nepomuk background. I'm not saying that
it should be used as it is, but the problems I listed at [1] might be
worth a look.

Hi there! Glad to hear you're writing another book.

I'm glad to hear you consider five years a short time. 2002 seems like
only yesterday to me :)

Peter's main point came from a perceived ambiguity in the rdfcal W3C
Note, about which namespace to use.

"unfortunately the spec at [3] leaves the question in limbo, using
either one or the other namespace at various points",
http://www.w3.org/TR/rdfcal/

The Note lists this as an unresolved issue,
"Note that NY:tz timezone is used as a datatype. Earlier, we used
separate properties for time and timezone, which is initially appealing
but problematic for reasons that are detailed in the
InterpretationProperties pattern.

* Objections were raised when this change was made to the original
...2002/12/cal/ical# schema. This design is using a somewhat
experimental2005-03-30 namespace name, ...2002/12/cal/icaltzd#."

...which cites Dan's msg of
http://lists.w3.org/Archives/Public/www-rdf-calendar/2005Mar/0015.html

It's clear from the Note that we don't yet have documented consensus
about the value of these different designs, so it is unclear which
pattern the SearchMonkey folk at Yahoo should be promoting.

In http://lists.w3.org/Archives/Public/www-rdf-calendar/2004Oct/0004.html
you suggest,

[[
Yes, yes. It's very welcome to roll back the changes in the schema of
current URI, as well as to discuss and develop modified schema with a new
namespace URI.

>[danc] The tests and conversion tools will migrate to the
>new schema, I think; I don't think I can afford to
>keep 2 sets of them around.

That's fine. Keep existing data as is, and move forward.
]]

It seems the existing Note pretty much captures things at this turning
point, which is why it confuses Peter by mentioning two different
namespaces.

I don't see any problem with the original namespace being unchanged and
stable. It should be fine to use, adopt and rely on. The question is
more: do we recommend people use it, or do we recommend people use the
later one with a changed design for timezones? Is anyone beyond Dan
making much use of the later design?

Hmm maybe we can ask the various RDF crawlers about this... take a look
at what has been published in the Web? Of course this wouldn't reflect
private usage, and calendar data is often private or intranet. Perhaps
we can also do Google Code searches or similar?

cheers,

Dan

Re: VCal namespace

Hi Kanzaki,

We're in complete agreement... However, the mistake has been made of not
deciding which namespace to use, and consequently in the past five years
or so people have started using one or the other.

Personally I don't mind if we choose one or the other, but at this
moment Sindice finds 139,000 documents using

http://www.w3.org/2002/12/cal/icaltzd#VEvent

vs. 25 documents using

http://www.w3.org/2002/12/cal#Vevent

The results are most likely heavily biased by the fact that Sindice uses
the former to represent microformats (and we've done the same so far at
Yahoo), but this is how much we have in terms of evidence.

Cheers,
Peter

Hi

I've been using RDFcal for five years in my project, and if the name
space changed this time, it's the second time upset in this short
period. It's very unfortunate for existing projects to have such an
unstable namespace as its building block.

If it is inevitable, please make it complete as soon as possible so
that current project will not waste more resources. If possible,

Hi Dan,

Here is what I suggest:

-- Correct mentions of the old namespace |http://www.w3.org/2002/12/cal#
in [1]:
---- Two occurrences in Section 4
---- Rewrite Section 7 to reflect that this namespace is deprecated

-- Add a visible note to [2] to reflect the change. On the side, I would
also suggest to reorganize the page a bit: it has a lot of old material
(referring to events and chats in 2002!) which have been probably
surpassed by the state-of-the-art.

We just have had a very successful VoCamp [1] behind our back, where we
started to discuss among others the issue of representing popular
microformats in RDF. This is a pressing question because large scale
semantic platforms such as Sindice or Yahoo's SearchMonkey would like to
treat microformats at the RDF level and at the scale at which some of
our systems work there is no possibility for reasoning. Therefore an
agreement on the mapping is required. It doesn't matter as much what
this agreement is, as long as it is an agreement ;)

You can see the outcomes of our current effort at [2]. One of the
problems we spotted was related to VCal. Apparently, there is still
significant confusion as to what the proper namespace for VCal is and
unfortunately the spec at [3] leaves the question in limbo, using either
one or the other namespace at various points.

So my question is: could we deprecate

|http://www.w3.org/2002/12/cal#

|in favor of

http://www.w3.org/2002/12/cal/icaltzd#

and reflecting this change in the documentation at [3] and at [4]?

Thanks,
Peter

INSEMTIVE 2008

1st Workshop on Incentives for the Semantic Web

http://km.aifb.uni-karlsruhe.de/ws/insemtive2008/

Located at the 7th International Semantic Web Conference ISWC2008
October 27th, 2008 (Workshop day)
Karlsruhe, Germany

Deadline for submissions: July 25, 2008 (11:59 PM CET)

Supported by the EU project Active www.active-project.eu

------------------------------------------------------------------------

--- Objectives ---

"The original Scientific American article on the Semantic Web appeared
in 2001. It described the evolution of a Web that consisted largely of
documents for humans to read to one that included data and inforation
for computers to manipulate. The Semantic Web is a Web of actionable
information derived from data through a semantic theory for
interpreting the symbols. The semantic theory provides an account of
meaning in which the logical connection of terms establishes
interoperability between systems. This simple idea, however, remains
largely unrealized." (Nigel Shadbolt, Wendy Hall, Tim Berners-Lee
(2006). The Semantic Web Revisited, IEEE Intelligent Systems.)

One of the reasons for this state of affairs, almost seven years after
the publication of the seminal article on the Semantic Web, has been
always considered to be the lack of high quality semantic content. A
critical mass of semantically annotated Web pages, semantically enhanced
multimedia repositories, as well as business?relevant, widely?accepted
ontologies would provide a feasible basis for the development of
semantic applications of immediate added value for it users, and for the
adoption of semantic technologies at industrial level. Despite a mature
set of techniques, tools, and methods for authoring semantic content,
one can observe very limited user involvement. The lack of semantic
content and the missing engagement of users can be traced back to the
missing incentive models incorporatd by semantic technology. This is
very contrary to the Web 2.0 movement which lives great popularity and a
huge amount of user contributions. Even though, there are also many
failing Web 2.0 tools, applications like Wikipedia, Del.icio.us, Flickr,
YouTube, Facebook or LinkedIn generate enormous user interest and
massive amounts of data. Each of those applications implements an
incentive that motivates people to contribute their time and human
intelligence.

--- Programme ---

The workshop will be organized as a full-day event. It is meant as a
forum for presenting novel research achievements and their prototypical
implementation, as well as for intensive discussions and exchange of ideas.
The workshop program will hence consist of presentations (for full
papers and short/position papers), demos, and enough time for an open
closing discussion.

--- Topics of Interest ---

The workshop addresses incentives for building the Semantic Web, i.e.
achieving tasks, such as ontology construction, semantic annotation, and
ontology alignment. It is intended as a networking event for discussing
and brainstorming ideas for motivating people to contribute to semantic
cotent creation. The workshop also seeks for original academic work in
the respective field including:

* Incentives for the Semantic Web
* Motivations and incentives of 2.0 applications
* Suggestions how those motivations can be applied in Semantic Web
applications
* Incentive structures both within enterprise intranets and the
open Web
* Games for knowledge creation and maintenance
* Tools exploiting collective intelligence and the Wisdom of Crowds
* Monetary and non-monetary rewards for semantic content authoring
tasks
* Empirical studies on the usage of Web 2.0 or social Semantic Web
applications

Call for Tender for STI International Semantic Web Site

2008-01-22T06:32:39Z

========================================================================
Call for Tender for STI International Semantic Web Site
========================================================================

Work description

The goal of the work is to enable the current STI International web site
(http://www.sti2.org/) with Semantic technologies:

- to overcome the range of limitations and problems with existing
approaches to creating, integrating and maintaining web-based community
information coming from heterogeneous sources,
- to benefit from the Semantic interoperability with existing Semantic
systems and the reuse of existing metadata.

Why we need this

The use of Semantic technologies will provide the following benefits:

• Information accessible for human and software systems.
• Highly configurable, extensible and maintainable web site in which the
overhead of adding new types of information and data is strongly
reduced. From an economic perspective, a Semantic portal will reduce the
personnel costs.
• Avoid the duplication of information existing in complementary and
heterogeneous resources, allowing the integration of information of
Semantic and non-Semantic data.
• Increase the Semantic interoperability with other Semantic and
non-Semantic based system through the use of metadata.
• Flexibility and support for the use of inference engines that infer
new information and metadata.
• Consistency checking of the STI International Semantic information and
other Semantic information distributed on the web.
• Flexibility for declaratively configuring read/write permissions over
the portal information, allowing different type of users simultaneously.
• Customizable user interfaces for searching and navigating the
information according to different type of users with different permissions.
• Capability for searching semantically, in addition to keywords-based
searches.

Functionality and Structure

The new Semantic driven website is based on the current website
(www.sti2.org) and similar in terms of the content and functionality. In
addition a member area that is only accessible by STI International
members will be established. This member area includes interactive
features as subscriptions to mailing lists, wikis for different service
areas and working groups, calendar for STI International related
meetings and events, download area for all related STI International
documents (e.g. talks, protocols, training material) and access to the
detailed individual member information (e.g. address, contact data,
subscriptions to mailing lists, member fee status, participation in
working groups and services).

Implementation Plan

Month 0: Call for tenders’ launch in which candidates should present
specific implementation and deployment plans, distinguishing:
• Development and deployment phase’s activities and costs
• Population process and costs, including a description of information
sources to be incorporated
• Maintenance activities and costs
• Description of similar deployments in use
• Proposal of a financing plan
Month 1: Deadline for submissions.
Month 2: Analysis of submissions, decision and contract signature.
Month 4: First version including basic functionalities and a range of
information sources selected by STI International.
Month 6: Second version including advanced functionalities and the rest
of information sources selected by STI International.
Moth 8: Final version.

Business Model
A business model for setting up the website and financing the
maintenance costs of the website has to be included in the submitted
proposal.

Submission

The proposal for STI International Semantic Web Site should be provided
to STI International CEO, Alexander Wahler (office@...).

The deadline for submitting the proposal is February 28th, 2008.

cfp: Role of Services, Ontologies, and Context in Mobile Environments (RoSOC-M '08)

2008-01-22T01:07:45Z

**** Apologies for multiple postings****

Call for Submissions

International Workshop on the Role of Services, Ontologies, and Context
in Mobile Environments
(RoSOC-M '08)

in conjunction with the 9th International Conference on Mobile Data
Management (MDM'08)
http://idke.ruc.edu.cn/mdm2008/

TIME AND PLACE of the Workshop: May 27, 2008, Beijing, China

SUBMISSION DEADLINE FEBRUARY 5, 2008

All the papers should be submitted in electronic format (pdf version)
using the link: http://www.easychair.org/MoSOC2008/

--------------------------------------------------------

GENERAL OVERVIEW of ROSOC-M

Today, computers are changing from big, grey, and noisy things on our
desks to small, portable, and
ever-networked devices most of us are carrying around. This new form of
mobility imposes a shift in
how we view computers and the way we work with them. Services offer the
possibility to overcome the
limitations of individual mobile devices by making functionality offered
by others available to them
on an "as-needed" basis. Thus, using the service-oriented computing
paradigm in mobile environments
will considerably enlarge the variety of accessible applications and
will enable new business
opportunities in the mobile space by delivering integrated
functionalities across wireless networks.

Network hosted mobile services will allow mobile operators and third party
mobile services provider to extend their businesses by making their
network services available to a
broader audience (e.g. developers, service providers, etc.); device
hosted service will allow great
potential for big innovations for applications and services that can be
provided by individual mobile
device owners. These mobile service-oriented systems offer
functionalities and behaviors that can be described,
advertised, discovered, and composed by others. Eventually, they will be
able to interoperate even
though they have not been designed to work together. This type of
interoperability is based on the
ability to understand other services and reason about their
functionalities and behaviors when necessary.

In this respect, mobile service-oriented systems can benefit from
marrying the Semantic Web, which
provides the infrastructure for the extensive usage of distributed
knowledge, to be deployed for
modeling services and add meaning, through ontologies, enabling
lightweight discovery and composition
of mobile services. The ability to appropriately combine mobility and
semantic grounded data sharing
has generated and is continuously triggering challenging questions in
several areas of computer science,
engineering and networking.

A third dimension is added when taking context information into account:
Now, we are no
longer dealing with the information system any more, but the real world
is intermingled with the
computing and will immediately affect and interact with the processing
of data and communication.
Real-world context information can help to more efficiently exploit the
limited resources in mobile
environments by supporting better ways to provide data relevant to the
user, to enable improved
interoperability with the environment and with other mobile users, and
to decide when and how to
process data. So far, the contextual and semantic aspects of mobile
environments have received
insufficient attention from the research community as the specific
intricacies and resource issues
of mobile environments have not been considered and in mobile data
management only limited attention
has been paid to context and semantics. In this workshop we plan to
address the interdisciplinary
issues of the domain and bring together researchers and industry
attendees from mobile data management,
knowledge management/semantics, distributed systems, service-oriented
computing, and software
engineering to discuss the common interests, share and exchange
expertise and results, appreciate
each other's results and contributions. The long-term goal is to provide
application developers with
facilities (middleware, infrastructures, agent systems, service
platforms, etc.) that enable the
development and deployment of context-aware applications in mobile and
pervasive environments.

Call for Papers: Coordination Models and Applications (CoMA)

2008-01-21T03:15:42Z

========================================================================
C A L L F O R P A P E R S
========================================================================

International IEEE Workshop on

Coordination Models and Applications (CoMA):
Knowledge in Pervasive Environments

http://mowi.salzburgresearch.at/wetice

At the 17th IEEE International Workshops on Enabling Technologies:
Infrastructures for Collaborative Enterprises (WETICE)
http://www.wetice.org

June 23-25, 2008
Rome, Italy

========================================================================

WORKSHOP INTRODUCTION AND OBJECTIVES
====================================
Coordination is significantly responsible for the effectiveness,
performance and quality of
complex systems and as a concept it is not restricted to
computer-based systems. The concept
is cross-sectional and a great impact may be reached in different
application areas if effective
methods and models can be designed, implemented, validated, and
deployed. Coordination, moreover,
is an essential prerequisite for collaborative and telecooperative
applications, which are of
prime interest to the WETICE series.

The CoMA workshop aims at the interdisciplinary aspects of
coordination in general, and examines
their application to ubiquitous and pervasive environments in
particular. The overall goal is to
support the users' collaborative intentions in such environments as
effectively, imperceptibly,
and unobtrusively as possible. The role of the use of data based on
formal knowledge models - as being
promoted in the Semantic Web initiative - is an emerging approach to
support collaboration and the
challenges associated with co-ordination of knowledge are a new focus
of this workshop.

The goal of this workshop is to bring together on the one hand,
scientists who are either
conducting research directly in pervasive computing, coordination
models and languages as well
as semantic coordination systems, or indirectly in related fields such
as distributed knowledge
systems, collaborative systems, CSCW, systems research, complexity
management, or process management.
On the other hand, this workshop particularly welcomes the
contributions of researchers and/or practitioners
who concentrate on concrete applications where a combination of
coordination, pervasive systems and potentially
semantic data appears to be beneficial, such as emergency management
or health care systems, and can report on that.

The workshop particularly focuses on discussions about coordination,
pervasiveness and knowledge, the
current state of research efforts, and practical experiences with the
clear vision of generating
mutual benefits for the participants. To support this, opportunities
for showcases,
demonstrations, and in-depth discussions will be provided. Eventually,
interdisciplinary and
joint efforts shall be fostered and future co-operations on research
activities shall be triggered.

TOPICS AND APPLICATIONS
=======================
All topics related to the interdisciplinary aspects of coordination are
welcome
as much as these are in some way relevant for or applicable to
ubiquitous and pervasive systems.
We particularly welcome submissions addressing issues of pervasive
knowledge coordination.
The following incomprehensive listing gives examples of such potential
topics:

* Theoretical coordination models and foundations for pervasive systems
* Coordination models and languages for knowledge (using semantic
data models such as RDF or OWL)
* Coordination middleware (such as space- or event-based approaches)
* Coordination mechanisms in (semantic) service-oriented architectures
* Distributed and P2P-based coordination
* Coordination in multi-agent systems
* Coordination dependent on context
* Location-based coordination models
* Strategies to cope with heterogeneity, dynamics, mobility and/or
pervasiveness
* Integration of and mediation between coordination systems
* Case studies, evaluations and assessments about the benefits of
(semantic) coordination
* Interdisciplinary aspects of coordination

Coordination and contained topics are multidisciplinary and, hence,
can be viewed as orthogonal to a multitude of pervasive application
areas which shall be explored in this workshop, too. Examples include
but are not limited to:

# Collaborative applications like CSCW, groupware, or games
# Emergency management systems
# Coordination in highly dynamic environments
# Health care systems
# Decision-support systems
# Geo-Collaboration
# Operations research
# Complexity-, constraint-, conflict-, and workflow management
# Special-purpose coordination languages and tools

Call for Submission

The adoption and ubiquity of modern Internet access provides rich and
varied opportunities for innovation and improvement of businesses. Over
recent years, developments have led to a shift in the way business is
conducted, from providing new and innovative service frameworks for B2B,
to increasingly sophisticated, Web 2.0 services to improve the B2C user
experience. Simultaneously, advances in the use of devices, as well as
AI techniques have provided better and more varied access to e-commerce
systems as well as facilitating greater autonomy in the way business is
conducted. The Internet offers unique opportunities for individuals,
businesses and governments to seek new ways of providing novel services,
both qualitatively and quantitatively at substantially lower costs.
Although many challenges remain, advances in Service Oriented
Architectures and Semantic Web have opened up new models and avenues for
research and exploitation.

The International Conference on Electronic Commerce (ICEC) provides a
forum to share invaluable experience of good practices and pitfalls in
strategy planning, design, development, engineering and implementation
of e-services.

ICEC 2008 will feature:
• Invited keynote presentations
• Panels on topical issues on technology, business and public policy
• Refereed paper presentations on emerging and continuing research issues
• Tutorials and workshops in seven thematic tracks
• Demonstration and posters
• An exhibition, and
• A doctoral consortium

The conference will be organized into several tracks, which focus on the
latest developments and innovations in e-commerce in the following areas
of interest:
1. Business-to-business e-commerce: adoption of IOS, technologies for
interoperable processes, and e-collaboration for global reach;
2. Business-to-consumer e-commerce: trends, problem areas, and solutions
with emphasis on emerging markets;
3. E-government, policy and law: state-of-the-art and future regulation
of e-commerce, including public strategies in limiting illicit
activities and copyright violations;
4. Business/Enterprise Architectures: state-of-the-art and strategies
for unifying extended enterprise resource base;
5. Mobile and pervasive commerce: alternative interaction metaphors that
facilitate context aware, geo-spatially relevant services to users in
novel environments;
6. Electronic Markets and Multiagent Systems: autonomous, intelligent,
decentralized systems, that utilized AI-based and game-theoretic
approaches to facilitate both heuristic and theoretically sound decision
making;
7. Semantic Web ontologies, rules and services: decentralized
knowledge-based systems and methodologies that support the exchange of
information (including workflows, policies, services and ontological
knowledge) in dynamic and heterogeneous environments.

Papers

Authors are encouraged to submit high-quality research papers describing
the latest research and developments in the above-mentioned fields.
Submissions encompassing other areas are welcome, but authors are
advised to contact program chairs to discuss relevance before submission.
Papers should not have been submitted for review, accepted for
publication, or already published elsewhere. All submitted papers will
be reviewed on the basis of technical quality, relevance, significance
and clarity. All accepted papers will be published in the conference
proceedings. Initial submissions for review should be no longer than 10
pages. Papers must be submitted in PDF, according to the ACM Proceedings
Format (http://www.acm.org/sigs/pubs/proceed/template.html).

Workshops and Tutorials

The Workshop Track is a multi-dimensional channel aiming to share a wide
variety of industry and educational knowledge and experience. This is a
useful channel to report on the latest trends in e-commerce, inform
others about cutting-edge technology and the necessary skills to advance
within the IS/IT profession. Workshops can be created to discuss the
challenges and achievements of new technologies and e-business
applications, educating students, innovating and working with the
industry, transferring and creating new knowledge between academia and
industry, and for other industry and academic related experiences. This
channel is used to contribute to our profession's body of knowledge
through the sharing of unique and timely findings.

Proposals for workshops and tutorials should include:
• Title of the workshop or tutorial
• Description of topic(s) and content(s) of the workshop or tutorial
• Aims (theoretical and/or practical) of the workshop or tutorial
• Detailed contact information of the workshop organizer(s) or tutorial
presenter(s)
• Length (half day or one day) of the proposed workshop or tutorial
• Short description of the audience to which the workshop/tutorial is
addressed and estimated number of participants
• Schedule and agenda of the workshop or tutorial
• Resources (other than room) required to be provided by the conference
organizer
• Proposals should be related to at least one of the conference themes

Please submit your workshop or tutorial proposal through the online

http://www.icec08.org.

Doctoral Consortium

The ICEC Doctoral Consortium aims at bringing together doctoral students
within the fields of e-commerce and e-business to open their work up to
discussion in an international forum, and to obtain valuable feedback
from their fellow scientists with respect to both topic-specific
research issues, and research methodology. Students will be asked to
submit an extended abstract (of about 5 pages), structured in accordance
to a pre-defined template, whose focus is on the key methodological
components required for a sound research narrative. Generally speaking,
priority will be given to 1st/2nd year PhD students, because they are
still in the process of defining the scope of their research. However,
all PhD students are welcome and encouraged to apply.

The Doctoral Consortium is open to all PhD students carrying out
research on topics related to electronic commerce or electronic business
(see below). The applicants are required to send an extended abstract of
their doctoral work, which should address the following aspects:

• What is the research problem of the PhD thesis and why is it relevant
for the e-commerce or e-business areas?
• What is the state of the art in the field, where do you see room for
improvement and why is it feasible to assume your work will have chance
to achieve progress?
• What are the main contributions expected?
• What are the real-world use cases (applications, target audience)
which are likely to benefit from your work?
• What is the general research approach followed?
• What has been achieved so far?
• What the evaluation method applied or planned to be applied?
• What are your plans for future work?
• Topics of interest to the Doctoral Consortium include (but are not
restricted to) the conference themes

The submissions should not exceed 5 pages and be formatted according to
the ACM Proceedings Format
http://www.acm.org/sigs/pubs/proceed/template.html). Applicants should
also specify (e.g., in a footnote to the paper) how long they have
worked on their doctoral work.

The selected participants will be given the opportunity to open their
work up to discussion in front of other students and an expert audience
(either in a regular presentation session or in a poster session).

Demonstration and Poster

ICEC hosts a demo track providing a stage for demonstrating cutting edge
applications in the field of electronic commerce. Demo applications may
comprise of academic prototypes as well as commercial innovations from
industry. The demo track takes place on one afternoon during the
conference. Submissions should describe the application in no more than
2 pages. Accepted authors are expected to prepare a poster depicting the
application's functionality.

Germs Taken to Space Come Back Deadlier

It sounds like the plot for a scary B-movie: Germs go into space on a
rocket and come
back stronger and deadlier than ever. Except, it really happened.

The germ: Salmonella, best known as a culprit of food poisoning. The
trip: Space Shuttle STS-115, September 2006. The
reason: Scientists wanted to see how space travel affects germs, so
they took some along — carefully wrapped
— for the ride. The result: Mice fed the space germs were three
times more likely to get sick and died quicker than
others fed identical germs that had remained behind on Earth.

"Wherever humans go, microbes go, you can't sterilize humans. Wherever
we go, under the oceans or orbiting the earth, the
microbes go with us, and it's important that we understand ... how
they're going to change," explained Cheryl Nickerson, an
associate professor at the Center for Infectious Diseases and
Vaccinology at Arizona State University.

Nickerson added, in a telephone interview, that learning more about
changes in germs has the potential to lead to novel new
countermeasures for infectious disease.

She reports the results of the salmonella study in Tuesday's edition of
Proceedings of the National Academy of Sciences.

The researchers placed identical strains of salmonella in containers
and sent one into space aboard the shuttle, while the
second was kept on Earth, under similar temperature conditions to the
one in space.

After the shuttle returned, mice were given varying oral doses of the
salmonella and then were watched.

After 25 days, 40 percent of the mice given the Earth-bound salmonella
were still alive, compared with just 10 percent of
those dosed with the germs from space. And the researchers found it
took about one-third as much of the space germs to kill
half the mice, compared with the germs that had been on Earth.

The researchers found 167 genes had changed in the salmonella that went
to space.

Why?

"That's the 64 million dollar question," Nickerson said. "We do not
know with 100 percent certainty what the mechanism is of
space flight that's inducing these changes."

However, they think it's a force called fluid shear.

"Being cultured in microgravity means the force of the liquid passing
over the cells is low." The cells "are responding not to
microgravity, but indirectly to microgravity in the low fluid shear
effects."

"There are areas in the body which are low shear, such as the
gastrointestinal tract, where, obviously, salmonella finds itself,"
she went on. "So, it's clear this is an environment not just relevant
to space flight, but to conditions here on Earth, including in
the infected host."

She said it is an example of a response to a changed environment.

"These bugs can sense where they are by changes in their environment.
The minute they sense a different environment, they
change their genetic machinery so they can survive," she said.

The research was supported by the National Aeronautics and Space
Administration, Louisiana Board of Regents, Arizona
Proteomics Consortium, National Institute of Environmental Health
Sciences, Southwest Environmental Health Sciences
Center, National Institutes of Health and the University of Arizona.

Introduction

2007-09-08T07:30:31Z

Hi all,

I just subscribed to this list and wanted to introduce myself before posting. I'm Rob and coding and design is my hobby. So do nothing fancy but think I can learn a lot from all posts coming by in this W3C mailinglist.

I have a portal called Indelv.com (http://www.indelv.com/) and post some news on standards just to keep track of what is happening in the field. I know the site is not fully standardized, but I am working on it when I have free time.

So if you have some cool news or found a nice article, send me a note, I will repost some of it on Indelv, so I will not loose track of it. Hope I see nice tips passing by on this mailing list and in the future I might be a bit better and can even assist with answers.

Kind regards and have a good weekend

Rob

We aim for a broad range of topics to be covered in terms of their industrial value and barriers to uptake, including (but not limited to):

* Ontology Engineering

* Metadata Extraction

* Reasoning

* Mediation

* Data Integration

* Semantic Web Services

* Search and Personalisation

* Ontology methodologies in business practice;

* Ontologies and corporate knowledge;

* Representation of knowledge and business processes;

* Linguistic representation in organizational knowledge;

http://chatlogs.planetrdf.com/swig/2007-06-28.html#T17-40-28
reminded me that rdfs:label is for human readable
labels, and VEVENT is computer code.

Oh... I also made cal:summar a subproperty of rdfs:label

I'm not sure whether the icaltzd is subject to this policy,
but just in case, as a reminder...

The 1st Asian Autumn School on the Semantic Web aims to teach its
attendees how to apply semantic technologies in their own projects
and environments. The school is targeted at young researchers and
other interested parties affiliated to academia or industry. It is
particularly our goal to bring together international experts in the
field and to invite the leading research groups in Korea to be part
of the program.

Course Topics
--------------------------------------------------------------------
Presentations by leading international experts in the field will
introduce the core technologies of the Semantic Web:

- Standard knowledge representation languages such as Resource
Description Framework (RDF) or Web Ontology Language (OWL), including
tools for exploiting their reasoning capabilities.
- Methodologies, methods and tools to build and manage ontologies.
- The current directions in Semantic Web Services, in particular the
Web Service Modeling Ontology (WSMO) and the related Web Service
Modeling Language (WSML) and Web Service Execution Environment (WSMX).

Tutorials, hands-on sessions and exercices
--------------------------------------------------------------------
Tutorials, hands-on sessions and exercises will provide additional
insights into the aforementioned topics and guide the students in
applying the technologies in specific situations. These learning
modules will be complemented by invited talks which report on the
deployment of semantic technologies in real-world business scenarios,
handed over by representatives of well-known international companies.
The participants will be involved in projects, in which they will
develop prototypical Semantic Web applications in small teams on the
basis of a pre-defined scenario specification.

Co-located events
--------------------------------------------------------------------
The Asian Autumn School on the Semantic Web will be co-located with
the International Semantic Web Conference (ISWC2007) and Asian
Semantic Web Conference (ASWC2007) in Busan, Korea. It will take
place one week prior to these conferences.

Call for papers: International Workshop on Service Composition & SWS Challenge (SerComp & SWS Challenge '07), November 5, 2007, Silicon Valley, USA

2007-06-22T02:23:56Z

----------------------------------------------------------------------------
-------------------
International Workshop on Service Composition & SWS Challenge (SerComp & SWS
Challenge '07) http://events.deri.at/sercomp2007/

at the 2007 IEEE/WIC/ACM International Conference on Web Intelligence (WI
2007) http://www.cs.sjsu.edu/wi07/wi/

November 5, 2007, Silicon Valley, USA
--------------------------------------------------------

GENERAL OVERVIEW

Composition of services in dynamic environments has received much interest
for its potential to support Business-to-Business (B2B) or Enterprise
Application Integration (EAI). One of such dynamic environments is the World
Wide Web, which makes available a huge and rapidly growing number of
heterogeneous services. Recent efforts to develop ontology languages for the
Web and ways of describing web services semantically in this environment
have resulted in a number of prototype systems that can dynamically combine
services and interact with them.

There are many different types of architectures that have been developed
around the concept of "services" - parties providing dynamic functionality
to other parties. As the number of services increases so does the need for
service reuse and service 'composability' - creation and provision of
complex value-added services resulting in composite services. Additional
infrastructure may well need to be defined to support composition in these
open architectures.

This workshop is composed of two initiatives: the third edition of the
Workshop on Service Composition and the fifthSemantic Web Services
Challenge.

This workshop aims to tackle the research problems around methods, concepts,
models, languages and technology that enable composition of services in the
context of the WWW. Of particular interest are the methodologies that enable
automatic or semiautomatic composition of services, semantic web service,
web services, and e-services.
The workshop especially welcomes contributions that exploit rich semantic
descriptions of web services for semi-automatic and automatic composition
using web intelligence and autonomous agents technology.

This workshop aims to bring together researchers and industry attendees
(e.g. leading modelers, architects, system vendors, open-source projects,
developers, and end-users) addressing many of these issues, and promote and
foster a greater understanding of how the composition of services in the
context of WWW can assist business to business and enterprise application
integration.

TOPICS

* requirements on service composition
* applications of WWW service composition
* web languages for describing services and their relevance to
composition
* web-based composition languages
* choreography and orchestration languages
* workflow models and languages and their relevance to WWW service
composition
* conversation models and languages for composed services
* applicability of agent technologies to WWW service composition
* formal models for service composition
* reasoning about service composition
* service composition engines and tools
* dynamic composition methods and algorithms
* discovery and matchmaking based dynamic composition
* execution and lifecycle management of composed services
* monitoring and recovery strategies for composed services
* security and privacy for composed services
* policies for composed services
* mediation in composed services
* reuse and versioning of services and compositions
* semantic approaches to composition
* composition modeling language standards
* composition with Web services, eServices, Semantic Web Services, GRID
services
* relation between WWW service composition and GRID service composition
* service composition and Service Oriented Architectures (SOA)

These topics indicate the general focus of the workshop, however, related
contributions are welcome also. Papers for the SWS Challenge will describe
how they solve the problems in the Challenge scenarios, which involve
various composition problems, and actually solving them by calling the web
services.

SUBMISSIONS

All submissions should be formatted in IEEE Computer Society style with a
page limit of 4 + 1 extra, and should be submitted in electronic format
using the link: http://wi-consortium.org/wiiat07/scripts/ws_submit.php.

All contributions will be peer reviewed by a program committee that will
incorporate well recognized experts in the area of service composition.

The Workshop proceedings will be published by IEEE Computer Society Press,
to be indexed by EI.

I started working with icaltzd in october 2006 I've written an ical
crawler for the Aperture Framework [1]. Now Aperture has become a part
of the Nepomuk Social Semantic Desktop project [2] (funded by EU).

My work involves creating two ontologies that might be relevant for this
discussion. The first is the Nepomuk Contact Ontology. It's main purpose
is to describe entries in addressbooks. It evolved from vCard, but now
it became more generic. Each Contact has multiple Roles and each Role
can have multiple ContactMedia (PostalAddresses, EmailAddresses etc.).
My goal was that each vCard entry can easily be expressed with NCO, but
an NCO contact can contain much more information that can fit into a VCard.

The second one is NCAL - Nepomuk Calendar Ontology. This one is a
more-or-less direct adaptation of RFC 2445. We didn't use ICALTZD
directly because it's in OWL (while nepomuk uses RDFS-inspired Nepomuk
Representational Language) and because of the problems with ICALTZD.
There are more of them. I've gathered them in section 7.2 of the
document available from [6] I hope it will help to start a new
discussion about ICAL RDF.

A new discussion is all the more relevant because RFC 2445 is to become
obsolete within a couple of weeks. See [3], the section about goals an
milestones. The changes in the document are described in detail on the
IETF Calsify status page [4]. See [5] for the exact diff between RFC
2445 and the proposed 2445bis.

The draft of the documentation of the ontology I'm working on can be
downloaded from [6] Most of this document is probably irrelevant to you.
You could skim through the 5. section (the one inspired by vCard) but
the most interesting part is section 7. It contains a detailed account
of the things I didn't like in ICALTZD and a process I adopted when
creating NCAL. I guess NCAL might be a starting point for the new ICAL
ontology.

The Protege files with the ontology itself are available at [7].
Remember that this is a work in progress and just about anything may
change :). They will be officially released to the general public after
acceptation by the Nepomuk Consortium.

All comments are welcome.
