Re: Implementations of XQuery Update Facility requested

Hello Xavier,

I had forgotten about the results that we collected back in 2008. Thanks for reminding me.

As XQUTS grew significantly between 0.7 and 1.0.0, an updated report would show "379 / 1 / 725", or 52.3% passing on Minimal Conformance for Qizx 2.1. If you are ok with that, then I'd be happy to include these results.

I look forward to your results for Qizx 3.1 in 2010.

Hello Andrew,

may I remind you that I sent you test results back in May 2008
for Qizx 2.1 and the test suite version 0.7 ? Surely enough, it is
not up to date but maybe it is worth publishing nevertheless?

Qizx 3.1 (to be released) is currently passing 92% of the newest
suite, but it has not yet been updated with respect to the June CR.
Unfortunately I don't expect to find time to get back to 100% before
end of the year.

Best regards

[ANN] W3C XML Query WG and XSL WG Full Text Test Suite

2009-07-09T16:57:41Z

Gentlepeople,

The W3C's XML Query Working Group and XSL Working Group are pleased to announce the availability of version 1.0.0 of the Query and XPath Full Text 1.0 Test Suite (XQFTTS) at http://dev.w3.org/2007/xpath-full-text-10-test-suite/.

XQFTTS 1.0.0 is the initial public release of this test suite. This release contains approximately 650 XQuery and XPath Full Text 1.0 tests embedded into either XQuery 1.0 expressions or XPath 2.0 expressions. We encourage implementors of XQuery and XPath Full Text to run XQFTTS 1.0.0 and send us their implementation reports. Implementors who are familiar with the XML Query Test Suite (XQTS) found at http://www.w3.org/XML/Query/test-suite/ will discover that the mechanisms used to run the two test suites are substantially identical. XQFTTS 1.0.0 does not contain any tests expressed in the XML syntax, known as XQueryX. A follow-up release of XQFTTS is planned for the very near future that adds the XQueryX tests to the existing tests.

We look forward to receiving reports that demonstrate sufficient implementation experience to enable us to transition to Proposed Recommendation in the third quarter or fourth quarter of 2009. We will continue to maintain and enhance the test suite after our transition to Proposed Recommendation.

static typing, formal semantics at risk

2009-03-10T18:02:01Z

Static typing fans,

The XPath and XQuery Formal Semantics document, and the
pessimistic static typing feature shared by XPath 2, XSLT 2
and XQuery, is at risk of being dropped, or at least no longer
being normative.

This is mostly because we don't have resources to do the work.
(there's also a question of to what extent the type system should
be optimistic or poessimistic, but since we don't really have
resources to keep it up to date, it's about to be gone-imistic).

I'm posting because if you are reading this, maybe you are
someone who has time and ability to help us out.

If so, please cantact me.

Thanks!

FT: TokenInfo and StringInclude definition

2008-12-11T06:28:27Z

Dear authors of XQuery Full-Text Specification,

Please clarify the following issues:

1. I am a bit confused with the definition of TokenInfo and StringInclude.

[Definition: A TokenInfo represents a contiguous collection of tokens
from an XML document. ]

[Definition: A StringInclude is a StringMatch that describes a
TokenInfo that must be contained in the document.]

the UML Static Class diagram of AllMatches shows one-to one
correspondece between StringMatch and TokenInfo.

But from the XML Schema definition :

<xs:element name="stringInclude"
type="fts:stringMatch" />

<xs:complexType name="stringMatch">
<xs:sequence>
<xs:element ref="fts:tokenInfo"/>
</xs:sequence>
<xs:attribute name="queryPos"
type="xs:integer"
use="required"/>
<xs:attribute name="isContiguous"
type="xs:boolean"
use="required"/>
</xs:complexType>

<xs:complexType name="tokenInfo">
<xs:attribute name="startPos"
type="xs:integer"
use="required"/>
<xs:attribute name="endPos"
type="xs:integer"
use="required"/>
<xs:attribute name="startSent"
type="xs:integer"
use="required"/>
<xs:attribute name="endSent"
type="xs:integer"
use="required"/>
<xs:attribute name="startPara"
type="xs:integer"
use="required"/>
<xs:attribute name="endPara"
type="xs:integer"
use="required"/>
</xs:complexType>

<xs:element name="tokenInfo" type="fts:tokenInfo"/>

follows that StringMatch can contain a SEQUENCE of tokenInfo. So, we
have one-to many relationship.

Please, clarify the right relationship between StringMatch and tokenInfo.

2. In section 4.2.7.9 FTDistance you have an example: ("Ford Mustang"
ftand "excellent") distance at most 3 words

And you say at the end : "The result for the FTDistance selection
consists of only the first Match (with positions 1, 2, and 5) and the
fifth Match (with positions 25, 27, and 28), because only for these
Matches the word distance between consecutive TokenInfos is always
less than or equal to 3. It is 1 for the first pair and 3 for the
second in the first case, and 2 and 1 in the second."

Here for the first match you have 2 StringIncludes (shown on the diagram):
1) first StringInclude with startPos = 1 and endPos=2
2) second StringInclude with startPos = 5 (endPos = 5)

But what is the consecutive pairs ? It looks like with have 2
StringIncludes and have only ONE pair and distance = 5 - 2 -1 = 2, but
you say " It is 1 for the first pair and 3 for the second in the first
case" what defines something different.

Please, clarify how do you define the consecutive pairs ?

Thank you in advance,
Peter Pleshachkov

RE: specifying text node filtering rules

2007-12-13T09:30:14Z

XQuery does not offer rule-based processing of this kind. For that, you want
XSLT. In XSLT it's very easy to express this kind of rule:

<xsl:template match="text()">
<xsl:value-of select="normalize-space()"/>
</xsl:template>

specifying text node filtering rules

2007-12-13T00:27:44Z

Hello! I wonder if the following is possible and cannot find an answer
to it. I use XQuery code to read an input XML document "in.xml" and
produce an output XML document "out.xml". I wonder if I can specify a
rule so that all text nodes copied from "in.xml" to "out.xml" are
filtered as follows: every group of consecutive whitespace characters
(tabs, new lines, spaces) are replaced by a single space character.
Given that text nodes are copied by many, diverse ways in my code, I
am not looking for a function manipulating strings (that should be
called whenever needed); this, apart from being a hardcoded procedure,
wouldn't be enough when copying element nodes containing text nodes in
their tree structures. Instead, I am looking for a way to specify a
general rule for filtering text nodes (e.g. like "declare
boundary-space strip;").

Thanks in advance.

Announce: XQuery Update Facility Test Suite, version 0.7

2007-12-08T09:32:59Z

The W3C XML Query WG has released version 0.7 of the XQuery Update
Facility Test Suite, which you can obtain from here:

http://dev.w3.org/cvsweb/2007/xquery-update-10-test-suite/Overview.html?rev=1.7

This test suite corresponds to the XQuery Update Facility:

XQuery Update Facility 1.0
http://www.w3.org/TR/2007/WD-xquery-update-10-20070828/

The XQuery Update Facility Test Suite was designed to test whether the
W3C XQuery Update Facility can be implemented interoperably as
published. If you have implemented the XQuery Update Facility, using
this test suite facility is a good way to ensure that your
implementation follows the specification, and to identify aspects of the
specification that should be changed if there are implementability
issues. Sending us your test suite results helps the XML Query Working
Group to satisfy the requirements to progress toward W3C Candidate
Recommendation status.

The XQuery Update Facility adds 4 new updating expressions to XQuery
1.0; insert, replace, rename, and delete. These expressions modify
instances of the XQuery 1.0 and XPath 2.0 Data Model (XDM). The XQuery
Update Facility also adds a non-updating expression, transform, which
returns an XDM instance that has been created by copying existing XDM
instances and then modifying them.

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

XQuery Update Facility 1.0 published as Last Call WD

2007-09-06T09:26:21Z

The W3C XML Query WG published the following documents as Last Call WDs early last week:

XQuery Update Facility 1.0
http://www.w3.org/TR/xquery-update-10/

XQuery Update Facility 1.0 Requirements
http://www.w3.org/TR/xquery-update-10-requirements/

XQuery Update Facility 1.0 Use Cases
http://www.w3.org/TR/xquery-update-10-use-cases/

The XQuery Update Facility abstract says:

"This document defines an update facility that extends the XML Query language,
XQuery. The XQuery Update Facility provides expressions that can be used to
make persistent changes to instances of the XQuery 1.0 and XPath 2.0 Data
Model."

The XQuery Update Facility adds 4 new updating expressions to XQuery 1.0; insert, replace, rename, and delete. These expressions modify instances of the XQuery 1.0 and XPath 2.0 Data Model (XDM). The XQuery Update Facility also adds a non-updating expression, transform, which returns an XDM instance that has been created by copying existing XDM instances and then modifying them.

The review period for these Last Call WDs ends on Oct. 31, 2007. The status section of each document specifies how you can provide comments to us.

Sorry, but that's not the right approach. What you've written says
"select the year column from all rows in the year table for which the
year column has the following character string value" and then you
give the letter 'y' followed by the letter 'e' followed by the letter
'a' followed by... In the second example, you're asking for rows in
which the year column contains the digit '2' followed by the digit
'0' followed by...followed by a space followed by a hyphen followed
by a space followed by the digit '1'.

This ought to do the job:

select year
from year
where cast(substring(year,1,4) as integer)
= cast(substring(:formcol,1,4) as integer)-1
and
substring(year,5,1) = '/'
and cast(substring(year,6,4) as integer)
= cast(substring(:formcol,6,4) as integer)-1

In that code, ":formcol" is the syntax for referencing the host
parameter provided in an EXEC SQL statement.

Hope this helps,
Jim

Well, I've always adhered to anything in the standard, so I really
had a bad feeling about this. Still, I think it should be possible to
do such easy things as getting the number of items deleted without
resorting to some scripting language etc. Also, I'm not sure how it
turns out, but if the single steps in an XQuery "script" really run
transactionally separated, getting this information might still be
problematic...

Hi Emma,

X-Hive simply allows to mix updating statements with non-updating
statements, i.e.

declare updating function local:foo() as xs:integer
{
let $items := ...
return (
do delete $items,
count($items))
}

You can download X-Hive/DB from http://www.x-hive.com/products/db/,
the download includes documentation.

Can not do this in the current version of the update facility.

This use case was accepted to be resolved as part of the Scripting Extension facility work – part 3.4 of the requirements: http://www.w3.org/TR/xquery-sx-10-requirements/#functionalities – returning values from expressions that have side-effects.

Hi,

The problem I am trying to solve is that with XQuery Update faicility, I will update an element and at the same time, I want the same element to be returned. Something like the following:

1. update a book element’s author

2. return the updated book element

Is there a way to do it in one query instead of two separate queries? And it looks like update expression does not return anything

Thanks,

When I implemented the XQuery update spec for X-Hive/DB I deliberately
chose not to follow that path, but rather to allow update expressions to
return values. I still can't see any need or technical merit in that
limitation, and it really hurts if you want to do something as simple as
returning how many items were changed. I think there should still be an
open bug in W3C's bugzilla about that issue.

2007-07-27T12:28:53Z

Hi Emma,

In the current spec, you can either change a data model instance with a
query that generates a pending update list, or do a transform or a
query, but you can't do both. And all expressions in an update are
evaluated within one snapshot.

The Scripting Extensions for XQuery will introduce statements, allowing
expressions to be evaluated after an update has been made. Only the
requirements document currently exists:

http://www.w3.org/TR/xquery-sx-10-requirements/

In the meantime, you can do this if you embed XQuery in a procedural
language.

Hope this helps!

The query below does not change the original document. Only the copied var $newVar is updated.
I need the $var to be updated and return the updated $var as well. Any idea? Thanks.

Emma:

If I am not mistaken, you can use a Transform expression, which will
return a value back.
Something like this:

let $var := fn:doc("works-mod.xml")/works[1]/employee[1]
let $var1 := <pnum>P1-1</pnum>
return
transform
copy $newVar := $var
modify do replace $newVar/pnum[1] with $var1
return $newVar

XQuery Update to return values

2007-07-26T12:02:18Z

Hi,

The problem I am trying to solve is that with XQuery Update faicility, I will update an element and at the same time, I want the same element to be returned. Something like the following:

1. update a book element’s author

2. return the updated book element

Is there a way to do it in one query instead of two separate queries? And it looks like update expression does not return anything

Thanks,

Emma

Maurice,

If you're going to mention XDuce, we should also mention CDuce and OCamlDuce.

Don't forget CQL, "Contextual Query Language".
http://www.loc.gov/standards/sru/cql/index.html

(It's "Common Query Language" in version 1.1 but renamed "contextual" in
1.2, a preview of which is available at:
http://www.loc.gov:8081/standards/sru/specs/cql.html)

XML-GL is currently evolved in XQBE (XQuery By Example).

XSLT and XQuery are in very active use, and are very widely implemented.
XQL is a precursor to XPath, and the inventors of XQL and XML-QL put
their later efforts into XQuery, which is the language they now endorse.
I don't know how active Lorel or XML-GL are.

Also of interest are extensions to existing languages to support various
subsets of XQuery, such as Microsoft's LINQ and IBM's XJ.

I have my final project in my university,and i have to find and compare all the
xml query languages.I have focused until now at Lorel, XML-QL, XQL, XML-GL ,
XQuery and XSLT.
Are there any other languages to search?
Does the most of these language (like xml-ql,xql and xml-gl) work nowadays?
XDuce is also a usable language?

Thanks for your question. It's a good one that caused the Working
Groups a few moments of head-scratching before we remembered why this
clause is present.

Elements may be validated against type definitions without having been
validated against an element declaration in at least two cases:

1) Validation was initiated by a request to validate a
particular element against a particular type.
(In section 5.2 of XML Schema 1.0: Structures, this
is item 1 in the list of ways validation can start.
In 1.1, the term 'type-driven validation' is introduced
to describe this way of starting validation.)

2) An element with no governing element declaration, being
validated in lax validation mode, has an xsi:type attribute
which identifies a type present in the schema.

According to section 3.3.5 of XML Schema 1.0, the properties
[validity] and [validation attempted] are present if "the
schema-validity of an element information item has been assessed as
per Schema-Validity Assessment (Element) (sec. 3.3.4)". In the
absence of an element declaration and the presence of the type
definition, clause 1.1 of Validation Rule: Schema-Validity Assessment
(Element) does not apply, and clause 1.2 does. So it's possible to
have [validity] = valid and [validation attempted] = full even when
there is no governing element declaration and thus no declared type.

I hope this helps. If you have further questions, please ask. If this
answer doesn't seem satisfactory, please let us know; in that case,
you might wish to open a bug report against the spec in the public
instance of Bugzilla on the W3C site, at http://www.w3.org/Bugs/Public
