The record of today's meeting[1] is now ready for review. I expect that some of the comments people made were not adequately captured; I hope that those present will augment the record, perhaps using what is recorded here as a reminder of what you meant to say.

CURIE and IPTC 2. issue 7: syntactic sugar for class attribute * Summary of Action Items _____________________________________________________________ CURIE and IPTC <benadida> http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2005Oct/0092.html Mark: I think the IPTC metadata will mostly be transported in newsml "packets" ... in an (XML) envelope ... not in the HTML payload Ben: CURIEs did two things for us: (1) they allowed abbreviation of URIs like QNames but without restriction on the 'name' part and (2) they were a convenient solution to the bnode reference issue Mark: note that Misha said that IPTC intends to use CURIE regardless of what XHTML2 does Ben: CURIE with []? Steven: IPTC is defining its own attributes, so they don't need the '[]' approach Ralph: the team hesitates to have another mechanism for referencing ... why not use entities if abbreviation is a big issue ... the bnode question hasn't bubbled up yet ... general unease about new syntax (square brackets in particular) ... any new syntax would raise concerns; it's not specifically about our choice of square brackets Jeremy: several concerns; partly about the length of identifiers, partly about bnode references ... the CURIE solution provides a way to not have to put all the complexity up front Ralph: perhaps if we had presented the requirements and the pros and cons of each of the options then the rationale for the CURIE solution would be better understood Ben: several of Mark's mails have the pros and cons of options we considered ... I'd like to start preparing a [rational] document next week Ralph: is the issue that xmlns doesn't work the way IPTC wants a real issue for us? Jeremy: yes, xmlns doesn't work the way anyone wants ... I've found several cases that will cause problems; e.g. embedding XHTML2 inside an [RDF/A] XHTML2 chunk Mark: IPTC is talking about using some other attribute than xmlns ... to declare the substitution rules ... might even permit the declarations to be contained in a separate document Jeremy: we've gone to CURIE to abandon syntactic restrictions on the right-hand side of QNames ... perhaps we can abandon the left-hand side of QName as well Mark: CURIE could define substitution mechanism without specifying the source of those substitutions ... even XPath is using namespace prefixes; no one has proposed entities ... I've [10]blogged about the CURIE solution last week and folks are commenting positively [10] http://internet-apps.blogspot.com/2005/10/curies-compact-uri-syntax-semantic.html Steven: Mark's blog entry was picked up in the [11]O'Reilly Developer Weblogs [11] http://www.oreillynet.com/pub/wlg/8196 issue 7: syntactic sugar for class attribute <benadida> [12]syntactic sugar for class attribute [12] http://www.w3.org/2001/sw/BestPractices/HTML/2005-current-issues#class Ralph: concerns about overloading of the class attribute ... the real use of class is to make CSS work, right? Steven: why do we need to do this if we use role? role and class are very similar but role has more clear semantics ... role is meant to do the right thing Steven: class is now also used for microformats Mark: when role was first proposed it was because class would be overloaded ... but the reason class would be overloaded was that it did not use QNames ... now class has been extended to define some semantic meaning but people feel class and role have different semantics ... it would be a mistake to not define a meaning for class Steven: this would be a big change for the entire Web community due to namespace defaulting ... people would not be able to use unqualified names in the way the used to use them Mark: if I want a foaf:address and also to style these in green I shouldn't have to duplicate more markup Steven: an unqualified name is supposed to be interpreted as in the local namespace Ben: we could define class to be a CURIE Mark: we could also define a different namespace defaulting rule Ralph: it would be too confusing to have different namespace defaulting rules <benadida> class="foo" Mark: we've defined the namespace rule to make rel='next' work the way we want, with next in a particular namespace Ben: if we want class="foo" to mean foo in a local namespace then we either have a 3rd namespace defaulting rule or class is a URI only, not a CURIE Mark: alternatively we can say that unqualfied value does not have a defined namespace ... e.g. the union attribute [in XML Schema] is defined to be based on the target namespace Ben: next meeting 8 Nov? Steven, Jeremy: regrets Ben: please use mailing list for additional comments Summary of Action Items [DONE] ACTION: Ben add "should rel, rev, and properties predicate be CURIE or CURIE/URI?" to issues list with a summary of the current status [recorded in http://www.w3.org/2005/10/25-swbp-minutes.html#action01] [DONE] ACTION: Mark send Ben the XML version of the new RDF/A draft [recorded in http://www.w3.org/2005/10/25-swbp-minutes.html#action03] [PENDING] ACTION: Mark report on the status of src attribute definition [recorded in http://www.w3.org/2005/10/25-swbp-minutes.html#action02] [PENDING] ACTION: Steven track and report on Role discussion before next Tuesday [recorded in http://www.w3.org/2005/10/18-swbp-minutes.html#action05] [PENDING] ACTION: Ben to put together the "ACID" test for XHTML2 RDF/A [recorded in http://www.w3.org/2005/07/26-swbp-minutes.html#action02] [PENDING] ACTION: Mark and Ben to check edge cases of inheritance in RDF/A [recorded in http://www.w3.org/2005/07/26-swbp-minutes.html#action06] [PENDING] ACTION: Ralph and Ben to augment the issues list [recorded in http://www.w3.org/2005/09/27-swbp-irc#T14-30-04] [End of minutes] Change Log $Log: 01-swbp-minutes.html,v $ Revision 1.2 2005/11/01 21:19:23 swick Cleanup for first publication _____________________________________________________________ $Revision: 1.2 $ of $Date: 2005/11/01 21:19:23 $
