logistics

LeeF proposes having a working meeting telecon on Thursday Oct 4 at 2:30 UTC.

scribe: not a full meeting - pushing on with preparation

EricP: Can't make Thurs - Wed better.

LeeF: Propose Oct 3 at 14:30 UTC.

Eric and Andy can make it.

unescaped xml in result format

<LeeF> AndyS: use case is ability to have, e.g. XHTML in a result format

<LeeF> ... so that you can use XSLT to produce a table with rich-text and links, images, etc.

<LeeF> ... right now the result format has a schema - needs to be well-formed XML and can be validated against our relaxNG or XML schema

<LeeF> ... looked around for examples of embedding xml

<LeeF> ... XML literals in RDF/XML

<LeeF> ... putting document in SOAP envelopes

<LeeF> ... there is a canonicalization (c14n) spec at CR

<LeeF> ... also "exclusive xml canonicalization"

<ericP> weak!

<LeeF> LeeF: would we have designs to lean on?

<LeeF> AndyS: Only one to reference would be RDF/XML

<LeeF> ... not an off the shelf XML solution AFAIK

<LeeF> LeeF: Do implementations do this?

<LeeF> AndyS: Joseki does not right now (escapes XML); Virtuoso does

SteveH: escapes XML

Chimezie: puts raw XML into DOM tree.

<LeeF> ericP, do you have an implementation of the result format that does/does not escape XML literals?

EricP: no use cases, haven't pushed on it.

(pp Ivan): Virtuoso embeds HTML in result set formats.

Round table :

Chair - for Openlink: have some investment and usage

<chimezie> Doesn't Atom do this with XHTML?

They wish they brought this up before.

<LeeF> AndyS: Looks like a deep black hole, not well sorted out right now

<LeeF> ... worried about schedule issue, esp. considering lack of editor for document

<LeeF> ... may uncover other issues not considered by RDF/XML - makes this a large design space

<LeeF> ... design of result format to have a schema was purposeful, means a loss but shoudl take that into account

Souri: currently do not generate XML - do return an SQL table with XML string literally as seen
... not worried about SPARQL supporting this feature

AndyS: example in Turtle"<tag/>"^^rdf:xmlLiteral

Chime: would like to know more : example from Atom?
... any tests?

<SteveH> Atom example: http://www.xml.com/pub/a/2005/12/07/handling-atom-text-and-content-constructs.html

Chime: no tests in test suite

<ericP> <literal datatype="xsd:string">&lt;tag&gt;</tag></literal>

<ericP> <literal datatype="rdf:xmlLiteral"><tag></tag></literal>

we already have to escape anyway for non-XML.

 

EricP: cool for language but special case that is new work.

LeeF: asks for energy level to edit the spec here (noting we have no active editor)

EricP: prefer to wait for XML general solution.

LeeF: suggests opening and postposing an issue.

<ericP> ericP: solutions i've seen are all successive approximations of "good enough"

<LeeF> PROPOSED: No change to the SPARQL XML Results Format that would allow unescaped XML values

Abstain: Openlink (Orri and Ivan)

Seconded: SteveH

RESOLVED

<scribe> ACTION: LeeF: open and postpone an issue on unescapes XML in result set format. [recorded in http://www.w3.org/2007/09/25-dawg-minutes.html#action13]

towards PR

Review status

QL: chair getting report generation to work portably

Next week - hope for report next week.

Protocol: Reminding EliasT as to progress.

SOAP: Joseki client - Virtoso server tested

Result format: will now go to CR

AndyS: DAWG tests serve as tests of Results format.
... but does not really test generation

Dave Beckett has provided XSLT to show transformation - used in SPARQLer.

HTTP testing should test generation (EliasT)

Not as rigorous as QL testing but adequate

Oct 2: bit tight for PR but wil try for that (else Oct 9)

<LeeF> PROPOSED: That given awareness of the last-minute issues surrounding unescaped XML and inline metadata in the SPARQL Query Result XML Format, the WG has decided to make no changes at this time and request publication of the document as a Candidate Rec

Seconded: EricP, AndyS

RESOLVED

LeeF: AOB?

(none)
