Ben: I've revived discussion of hGRDDL on the GRDDL WG list; see "Re: Review of testlist1#rdfa"
... the idea was that given lots of deployed microformats, perhaps it would be good to use GRDDL to transform them to RDFa to preserve rendering characteristics rather than directly to RDF

Michael: I like the idea

Michael: the Wiki seems to be dropping some updates in the RecentChanges report
... I've edited http://www.w3.org/2006/07/SWD/wiki/RDFa_Use_Cases_and_Requirements 5-6 times but only the most recent appears

<mhausenblas> http://www.w3.org/2006/07/SWD/wiki/RDFa_Use_Cases_and_Requirements?action=info

Michael: the final version does show all the changes
... but the recent changes page doesn't show all the changes

ACTION: Ben to look into Science Commons use case [recorded in http://www.w3.org/2006/12/11-htmltf-minutes.html#action04] [CONTINUES]

Ben: I'm talking with Science Commons. Their use cases tend to be quite long so I'm working on distilling something down to the core

ACTION: [DONE] Ben update the issues list [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action03]

Ben: shall we move the issues list to the wiki?

Michael: I'll volunteer to move it

ACTION: Michael move the issues list to the wiki [recorded in http://www.w3.org/2006/12/18-htmltf-minutes.html#action03]

<mhausenblas> http://www.w3.org/2001/sw/BestPractices/HTML/2005-current-issues

ACTION: Ben add a forwarding pointer to http://www.w3.org/2001/sw/BestPractices/HTML/2005-current-issues when the new wiki issues list page is done [recorded in http://www.w3.org/2006/12/18-htmltf-minutes.html#action04]

ACTION: [DONE] Mark to report on schema progress [recorded in http://www.w3.org/2006/12/11-htmltf-minutes.html#action05]

Mark: I've talked with Shane and we're going to move forward using some templates we already have

ACTION: Mark produce RDFa XHTML 1.1 module and spec [recorded in http://www.w3.org/2006/12/18-htmltf-minutes.html#action06]

Mark: the module is already complete. I've enlisted Shane because of his understanding of XHTML modularization and his ability to write specs quickly

Ben: does your current module have the latest striping and class decisions incorporated?

Mark: no, not yet
... but it won't take long to bring it into line

<benadida> looking at --> http://www.w3.org/2006/12/04-htmltf-minutes.html#ActionSummary

ACTION: Elias to send by email examples of HTML markup that could be problematic with reification [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action05] [WITHDRAWN]

ACTION: Elias to send email to list with use case from IBM [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action10] [CONTINUES]

ACTION: Elias start an FAQ [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action04] [CONTINUES]

ACTION: Mark produce more examples of applicability of n-ary relations from IPTC documents [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action08] [CONTINUES]

Mark: I have to reproduce these from memory

ACTION: Mark write examples/tests of striping support [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action07] [CONTINUES]

ACTION: Steven to put together sample XHTML2 doc with all mime type, etc.. [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action09] [CONTINUES]

Use Cases

ACTION: Michael to research extended usages of RDFa in Wikis [recorded in http://www.w3.org/2006/12/11-htmltf-minutes.html#action03] [DONE]

Michael: I added several
... I tried to separate system metadata from others

-> Semantic Wiki use cases

Michael: does 8.1 capture what you were thinking, Ben?

Ben: begins to capture
... in a semantic wiki there are triples all over the place; every link has a relationship

Michael: I could go into more detail but I really wanted to show that without any user action there is already metadata there and RDFa could be provided

Ben: can point out that all the triples from the semantic wiki can be included in the HTML

Michael: I'm not so deep into semantic wikis to know if they want to go into client-side RDFa
... they're currently constructing RDF on the server side from the raw page source

Ben: I need to resync on this; I've talked with Stefano Mazocchi

ACTION: Ben look at Semantic Media Wiki use case [recorded in http://www.w3.org/2006/12/18-htmltf-minutes.html#action15]

Michael: PDF use case
... converting PDF to HTML can preserve the metadata using RDFa
... Mobile Device use case; I looked quickly at DELI and it seems feasible to create this on the fly

Mark: doesn't seem quite the right way around; CC/PP is delivered by the client to the server

Ralph: that is my understanding as well; the server does some processing based on the client describing its capabilities

Mark: role attribute is used now a lot in the mobile community
... to describe, e.g. that a div is a navigation bar or a footer
... with CC/PP you know what the device can do so the server can optimize the placement of such things for the device

Michael: Publishing use case
... to emphasize use in blogging community

<MarkB_> On blogging: http://chem-bla-ics.blogspot.com/2006_12_01_chem-bla-ics_archive.html

<MarkB_> This guy is talking about using RDFa for chemistry.

Michael: might be nice to approach del.icio.us

ACTION: Michael review Mobile Device use case [recorded in http://www.w3.org/2006/12/18-htmltf-minutes.html#action16]

Mark: chem-bla-ics is an example of a focussed blog that is more than simply a personal page

Ben: chemisty example might be better to go with Science Commons use case rather than just blogging

ACTION: Ben add chem-bla-ics use case to a science use case [recorded in http://www.w3.org/2006/12/18-htmltf-minutes.html#action17]

Mark: this also shows a need for namespaces

Ben: copy-and-paste use case is Mark's

Mark: yep, I'll work on it this week

Ben: I've received suggestions that the use cases be more consumer-focussed and less publisher-focussed
... add more story lines, as the use cases are never just one-way
... next 2 Mondays are holidays. Are we able to meet later during the week of 1 January?

Mark: I'll be working off and on, but perhaps we can communicate more by email

Ben: next telecon will be 8 Jan then; we'll need to have a complete document by then to send to the WG for the 9th

Ralph: I'd like to see more detail in story lines in the use case document. Most of the detail is currently buried in the markup. This works for us but not for the general reader.

Ben: yes, I hope to flesh out the story lines following the GRDDL example

Ralph: from the use cases, we should be able to distill out requirements
... summarized in a "list of requirements."

<mhausenblas> http://www.w3.org/TR/webont-req/

Michael: where are our requirements? they should be called out specifically, as in the OWL UCR document

Ralph: I agree but I'm pessimistic about the available time

Michael: so we shouldn't claim that this document has requirements yet

XHTML 1.1 module status

Ben: we have Mark's update
... is it likely to be ready by 8 Jan?

<benadida> --> http://www.w3.org/2001/sw/BestPractices/HTML/2005-current-issues

Mark: I hope so -- I'm keeping an eye out for Shane

Issues

Ben: I want to particularly highlight issues 4&7 role & class)

-> Role Attribute

Mark: I'm happy with the proposal

Michael: whatever we decide needs to go into the RDFa syntax document soon

Ralph: I'm generally persuaded by Mark's arguments

Ben: we should confirm Steven's agreement
... issue 12 - CURIEs in predicate attributes
... I'm of the opinion that these should be CURIE/QName only, and not try to add [] syntax

Ralph: the further we get from current HTML practice the harder we make our lives

Ben: sounds like we have consensus for just CURIE only

Ralph: I need to raise red flags about presuming a CURIE solution, especially for XHTML 1.1

Mark: we don't need to drop CURIEs just because of XHTML 1.1

Ben: issue 18 nested meta and link
... proposed resolution is to look up the tree for a meta containing @about
... in Bob Ducharme's example in the use case, do we agree that the interpretation is as Bob suggests? Making statements about the same subject

Michael: I have a problem with reification in general. I doubt it's wise to include it in the first version.

Mark: this isn't reification
... we don't get reification until we put meta inside non-meta
