[PROPOSAL] HISE

[Rafal Rusin]

Please discuss this proposal:

http://wiki.apache.org/incubator/HISEProposal

------------------------
Abstract

HISE will be an implementation of WS-Human-Task Specification. It will
stand for Human Interactions Service Engine.
Proposal

HISE is to provide a deployable component ready to interpret human
interactions defined in xml files, as specified in WS-Human-Task 1.0
Spec, as well as expose taskOperations Web Service for tasks
management.

Note that this proposal covers only services implementation, not
including any web consoles. So it will contact with external world
using Web Services.
Background

WSHT project is beeing developed at TouK. It is currently used in
other projects by wiring up Spring beans provided by WSHT.

In current version, there is implemented about 20% of spec, which
includes task creation, assigning, retrieval. Persistence is
implemented. Currently, there are no task escalations and
notifications.

WSHT project is beeing donated to Apache Incubator to become HISE
project at Apache.

Rationale

There's a need for an engine which will interpret high level people
interactions definitions. There's no need to reimplement human
interactions in various projects from scratch (handling notifications,
escalations, tasks lifecycles, tasks reassigning). So such project
will follow DRY rule in SOA world.

There was some discussion before, which pointed that this kind of
project would be desired at Apache
(http://markmail.org/thread/es3h3yprjrttxhlu).

There was also Agila project in Apache Incubator, which was meant to
implement Human Workflow solution, but it's abandoned (probably
because of too broad scope - it included BPEL engine implmentation and
web console for management, details are here:
http://svn.apache.org/repos/asf/incubator/agila/trunk).

So in HISE there's aim to shorten this scope and implement only
services for WS Human Tasks spec. This would consist of 2
distributions (war and jbi) which would expose web services for tasks
management. There was some interest on ServiceMix mailing list too, so
jbi distribution would be desired
(http://markmail.org/thread/svyxd6xrm2tbwnsz).

Initial Goals

Currently, there's only POJO based possibility for connecting with
WSHT services. The goal is to add Web Services based distributions.
Those will include WAR and JBI distribution.

Second thing is to implement remaining WS-Human-Task spec. It will
include adding scheduler, implementing time notifications and adding
tasks escalations.

Third thing is to migrate Hibernate JPA to OpenJPA for licensing reasons.

Future plans (after 1.0 release) include OSGi bundle distribution to
increase wide adoption of HISE.

Current Status

Meritocracy

WSHT project originally was developed at TouK company by a set of
committers. All of those committers did a contribution to this
project, so they have required merit.

TouK currently has one committer in Apache ODE project, which is
expected to share knowledge about meritocracy inside community.

Community

WSHT has currently a small community consisting of developers inside
TouK company. This is due to short life of this product. It was
recently exposed to public and there's a plan to expand community at
Apache Incubator.

Core Developers

The core developers of WSHT are from TouK company. One of the
committers is already an Apache ODE committer. All developers from
initial committer's list are experienced in open source development,
since they all built this project to current usable status.

There's a plan to increase diversity of developers among various
companies. This is planned to be done at Apache Incubator in the
meritocratic way.

Alignment

The current code base is targetted for use inside Spring by creating
specific beans. But the goal is to add WAR and JBI distributions,
which will increase possibility to adopt HISE in J2EE and JBI SOA
worlds. Potential projects benefiting from HISE are Apache ODE (by
combining BPEL processes with human interactions), Apache ServiceMix
(by using service for human interactions in ESB), Apache CXF and
Apache Axis (by using human interactions services from other deployed
Web Services).

It's also expected to migrate from Hibernate JPA to OpenJPA for
underlying storage.

Known Risks

Orphaned products

Initial contributors are vendors of this product. So there's no risk
or warnings for abandoning this project.

Moreover there's already an interest from external communities to join
this project for development when it enters Apache Incubator.

Inexperience with Open Source

WSHT was started as a closed source project.

Core developers are already experienced with other open source
projects including Apache OfBiz, Apache ServiceMix, Apache ODE. One of
the initial committers is a committer in Apache ODE project and is
expected to share knowledge of open source development process among
others.

WSHT current code base also depends on various open source projects
like Apache CXF, Apache Geronimo and it was developed by core
developers.

Homogenous Developers

WSHT includes committers from only one company (TouK).

Current committers know each other from TouK, so they are not really
homogenous. This is expected to change during incubation.

Reliance on Salaried Developers

All of the developers at TouK are salaried developers. This is
expected to change during incubation phase.

Relationships with Other Apache Products

OpenJPA will be used by HISE for it's internal storage. Apache CXF
will be used to expose Web Services to external world. Apache
ServiceMix will be used to expose and test WSHT services as JBI
service.

Maven2 is used for building.

There's no competition among other Apache projects for this project.

An Excessive Fascination with the Apache Brand

WSHT is donated to Apache because of ability to gather communities
among other projects (Apache ServiceMix and Apache ODE) and external
communities both developers and users. This donation of WSHT project
is for increasing contacts and visibility in open source world and to
develop a satisfying implementation for WS-Human-Task spec.

This spec currently has closed source implementations usually bricked
up with larger products. HISE is expected to provide an open source
solution for WS-Human-Task spec, which may be adopted in those
projects too to follow DRY rule among various companies.

Initial Source

WSHT is the only code base for HISE.

WSHT project has been developed since April 2009 at TouK.

It was used to vend inside larger products. It was developed from the
beginning under Apache 2.0 License with aim to become open source
project.

under Apache 2.0 License).

Rafal,
I think the proposal is reasonable, and well defined scope (a
particular spec) and nothing that sticks out for me at the moment.

Matthieu@ ; Not signing up to be Mentor??

I doubt I will have a lot of time to devote to this project, but I'll
be happy to help (if you need any) on the JBI side ...

I'm already champion so I was waiting to see if others would be tempted to
help, the more the merrier :) But I'll add myself if the project ends up
being short on mentors.

So anyone else willing to mentor HISE? I can act as mentor too but a third
would be nice.
