<pauld> trackbot, init

<trackbot> Tracking ISSUEs and ACTIONs from http://www.w3.org/2005/06/tracker/databinding/

pauld: no objections for the last minutes

<Yves> Agenda: http://lists.w3.org/Archives/Public/public-xsd-databinding/2006Jan/0025.html

pauld: all are welcome to the WG meeting
... lets go through briefly through the issues we discussed last time
ISSUE-5: The open enumerated type

paulb paulb: wonders about the value of this pattern for databinding

paulb: proposes to tackle issue 9 first
ISSUE-9: Support for xs:union

paulb: we use unions in our organization
... I haven't given it serious thought but I know that XQuery struggled with it
... I think the schema tool should at least support unions to the level of Xquery

sekhar: is it a strongly typed object that you get from XQuery?

pauld: what is the JAXB support for unions

sekhar: JAXB used to return a strongly typed object
... JAXB had a complex algorithm to calculate a common super type
... will find more info for the next telcon

<pauld> ACTION: svajjhal to report on JAXB support for open enumerated type [recorded in http://www.w3.org/2006/01/17-databinding-minutes.html#action01]

<trackbot> Created ACTION-8 - Report on JAXB support for open enumerated type [on Sekhar Vajjhala - due 2006-01-24].

sekhar: Union is a case we don't have a strong mapping to a programming language
... I will look into the enumerated type support in Java and get back to the group

<pauld> discussion of using open enum for versioning

paulb: people use it for versioning or localization

pauld: I want to revisit this issue the next time when sekhar comes back with more info
ISSUE-10: Mapping Element and Type names

paulb: there's no generic rule that is applicable to all languages
... we may have recommendations that say how QNames are mapped to language identifiers

jonc: we may not allow the full use of XML here - to make it a safe for most languages

sekhar: we should leave the job to the databinding vendor

<Yves> the length issue reminds me of the issue of internationalization of domain names

<Yves> (utf-5)

paub: what would a databinding tool do if I have a million character long element name ?

<pauld> ACTION: pdowney to propose text for ISSUE-10 [recorded in http://www.w3.org/2006/01/17-databinding-minutes.html#action03]

<trackbot> Created ACTION-9 - Propose text for ISSUE-10 [on Paul Downey - due 2006-01-24].
ISSUE-7: xsi:nil and minOccurs=0

pauld: I think Eric has some strong ideas on this, can someone talk to him and propose some concrete text?

<scribe> ACTION: jonc to write down about ISSUE-7 :xsi:nil and minOccurs=0 [recorded in http://www.w3.org/2006/01/17-databinding-minutes.html#action02]

<pauld> ACTION: jcalladi to own and move ISSUE-7 forward [recorded in http://www.w3.org/2006/01/17-databinding-minutes.html#action05]

<trackbot> Created ACTION-11 - Own and move ISSUE-7 forward [on Jonathan Calladine - due 2006-01-24].
ISSUE-8: Using patterns to constrain numerical types

paulbas an editor of XML Schema 1.0 datatypes, I'm very aware of this issue - I said at the time it was a bug!

<pauld> ACTION: pbiron to propose text for ISSUE-8 [recorded in http://www.w3.org/2006/01/17-databinding-minutes.html#action04]

<trackbot> Created ACTION-10 - Propose text for ISSUE-8 [on Paul V. Biron - due 2006-01-24].
