Ralph: Not sure yet

Manu: Mark, beware of live demos

Steven: Yes, I had a similar problem yesterday at a talk

Ben: Please demo my clipboard if you have time

[Discussion of current uses of RDFa]

Status of Implementations

Ben: We need this information to show that there is progress

Mark: My implementation is coming on nicely
... the RDFa part needs to be modularised still
... so that people could pick it up separately

Ben: Is it a part of Sidewinder?

Mark: No, it is 3 or 4 javascript files
... in libXH
... as I call it

Ben: Can it manage the test cases?

Mark: Yep

Ben: We have Ivan's Distiller, up to date
... Elias's Pythion implementation, not up to date
... there is Operator

Manu: Not up to date yet
... Operator will be in Firefox 3, and then in Songbird
... so RDFa will be just there

Ben: My Javascript implementation is not yet up to date
... the bookmarklet
... then RDFa Monkey, I don't know the state

<RalphS> RDFa monkey

Ben: Fabien's XSLT, it is up to date, modulo a whitespace issue

<RalphS> (RDFa monkey home page cites Elias' test files, not the more recent ones)

<scribe> ACTION: Ben to add implementations page to RDFa.info [recorded in http://www.w3.org/2007/09/27-rdfa-minutes.html#action08]

<benadida> implementations -> http://esw.w3.org/topic/RDFa#head-681001ee6c73e87bd692e29693b3904e462fd9f2

Ben: there are some other implementations, Java and Python

Manu: How about IE? I heard they are adding microformats

Shane: How about Chris Wilson?

Ben: Do you want to talk to him?

<scribe> ACTION: Shane to contact Chris Wilson [DONE] [DONE] [recorded in http://www.w3.org/2007/09/27-rdfa-minutes.html#action09]

<RalphS> list of some RDFa implementations

Status of Test Cases

Ben: Deferred till next time
... Isee your message about href everywhere Shane
... we did resolve to accept that

Shane: Yes, and I have today fixed that

Ben: Should we update the editor's draft and tell the reviewers?

Ralph: It would be good

Shane: I made a couple of editorial fixes too

<scribe> ACTION: Shane to send a link to new editor's draft to Ben [recorded in http://www.w3.org/2007/09/27-rdfa-minutes.html#action10]

XHTML1.1 Namespace for rels

http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2007Sep/0216

Ben: There is a problem that the XHTML namespace doesn't end with a hash or slash

Mark: In the section on unprefixed values, I say that it uses the XHTML namespace with a hash on the end
... but we should move away from the idea that these are namespaces
... so we are not talking about changing the XHTML namespace, but defining the prefix
... but there is a problem with overlap with the role attribute
... they are so close, they ought to use the same system

Shane: There can't be multiple default prefixes for CURIES

Ben: But rel can have a magic property using reserved words

Steven: I would be happy if we could avoid special rules and magic

Ben: I think it is a special case because of backwards compatibility
... rel="foobar" is not even allowed

Mark: It is if you have a @profile
... so there are docs with a profile, with non-HTML rels
... and quite valid therefore

Ben: So the specific issue
... we do need a default prefix URL, alsoi that ends in a hash or slash

Steven: Why does it matter?

Mark: Because of round-tripping, which strictly RDF doesn't support
... but is a sort of standard practice
... in one case we would have the concept of xhtmlnext, as opposed to xhtml:next
... it is only convention

Ralph: I like the idea of Shane's to use Apache redirecting to redirect xhtmlnext to something else

Mark: Why do we care; we can add a hash without a problem
... We can add the relations to their own subnamespace
... otherwise just straight to the XHTML namespace

<benadida> example http://creativecommons.org/ns#

Ben: That is the CC namesapce

<RalphS> Shane: XHTML already has things under xhtml/ so I would expect objections to the simple concatenation xhtmlnext

<benadida> /1999/xhtml/ns#

Mark: In the Modularization schemas we have 1999/xhtml/datatypes

<benadida> /1999/xhtml/vocab#

<benadida> /1999/xhtml/?#

Mark: so we could have 1999/xhtml/vocab# or something

Ben: I like the word vocab as being general
... anyone object?

Shane: Mostly harmless

<benadida> PROPOSE that we use 1999/xhtml/vocab# as the prefix for next, prev, etc...

Ben: Deciding about nofollow is another issue

Ralph: Second

Ben: Opposed?

Mark: We can't speak for the whole XHTML2 WG, but I think it is the best option
... +1 to it

RESOLUTION: that we use 1999/xhtml/vocab# as the prefix for next, prev, etc..

<ShaneM> New draft of rdfa-syntax is at http://www.w3.org/MarkUp/2007/ED-rdfa-syntax-20070927/

Ben: This doesn't solve the issue of whether we should special-case the the legacy rels
... we'll treat that another week
