SWBPD RDF-in-XHTML TF

 

-> previous meeting 2005-04-12

bnode in RDF/A

Ben: Mark writes that he may have found a bug in his bnode proposal

Ben: Mark's proposal is to use ID and about attributes to denote bnodes vs. named nodes

Steven: I thought I had found some internal inconsistencies
... I sent mail about this and hoped that Mark would clarify my understanding

Ralph: I haven't yet investigated this fully
.. I did like where Mark was headed when we talked about it

Jeremy: I haven't analysed Mark's proposal either

ACTION: JJC & Ralph analyse Mark's bnode proposal
[recorded in http://www.w3.org/2005/05/03-swbp-minutes.html#action01]

Jeremy: target to do bnode proposal review by 24 May

XHTML2 Last Call status

Steven: HTML WG is close to Last Call
... we are awaiting a schema; hope to get the schema this week

ACTION: Ben to Provide RDF/XML examples and english description to Steven and Mark (use cases)
[CONTINUES]

Steven: I am speaking at the News Standards conference on 24 May
... talking about metadata in XHTML2
... may show how to do RSS in RDF/A
... will put slides in http://www.w3.org/2005/Talks/

BenA: Creative Commons is very excited about RDF/A -- want it to be a standard soon

GRDDL editor

Ralph: my primary concern, as I wrote in mail, is insufficient evidence of community support to work on GRDDL
... people are apparently not willing to give it very high priority

Jeremy: there is a lot of enthusiasm for RDF/A in HP
... HP doesn't believe it will be possible to scrape the current Web for metadata in a reliable way
... that seems to be the use case for GRDDL

Ralph: I'm not sure that GRDDL is akin to scraping
... I have a bias against scraping, because no guarantee of author's intent
... the document author may or may not have intended the scraped metadata
... GRDDL addresses this problem by including some additional markup
... that says that the author *did* mean that metadata
... what GRDDL really promises is to allow those who design non-RDF XML schemas
... to extract semantics from their other schemas
... CC has expressed interest in GRDDL for pre-XHTML2, where scraping is not a good idea

Ben: Creative Commons did hope for an ability to use non-standard or other XML schemas to embed semantics
... e.g. other document types that want to use CC licenses but that have not bought into RDF yet
... CC apparently has the largest interest w/in the current WG to work on GRDDL
... should I advise CC of the need for additional resources?

Ralph: Dom and Dan will probably do most of the work
... but they need someone from the WG to attend the meetings
... it probably needs to be someone who isn't Creative Commons, expressing other use cases and interests

ACTION: Ben to go back to CC and discuss the GRDDL situation
[recorded in http://www.w3.org/2005/05/03-swbp-minutes.html#action03]

ACTION: Tom Baker and Gavin to get feedback about use of RDF in XHTML in their respective communities
[CONTINUES]

Ralph: Gavin gave his verbally at the 21 April WG telecon, we asked for email

ACTION: Ben to talk to Jeremy about HP feedback [DONE]

Action Review

ACTION: DanBri RDF schema for new XHTML2 namespace elements
[CONTINUES]

ACTION: Steven to send email about latest draft of RDF/A included in XHTML 2
[DONE]

Steven: I thought I'd done this
... the latest RDF/A draft is public
... there is only one RDF/A draft
... the latest XHTML2 editor's draft is not public

Ben: is RDF/A part of the XHTML2 editor's draft or only in spirit?

Steven: only in spirit
... my intention is that the XHTML2 draft is more precise than the October RDF/A draft

Ralph: so the current editor's draft has the language you expect the last call to have?

Steven: unless you have comments, that's the text that will go into last call
... the current XHTML2 editor's draft is Member-visible and has the expected text

<Steven> "22.2. Meta and RDF

<Steven> The metadata attributes can be used to generate RDF statements. The attributes rel, rev and property represent predicates. The predicate is obtained by concatenating the namespace URI and the local part of the Qname of the attribute value. For attribute rel, the subject is the about property, and the object is the value of the href attribute; for attribute rev, the subject and object roles are reversed. For attribute property, the subject is the about property, a

ACTION: MarkB to email TF with his bnode proposal -- that (1) any node with @id is an anonymous node; (2) that an @href with a fragment refers to these nodes (like @rdf:nodeID)
[DONE]

next meeting: 17 May

Jeremy: regrets for 17 May and 31 May
