Introductions and Request for New Agenda Items

DanC: I'm your W3C team contact. If the web site is broken or whatever, write to sysreq@w3.org and copy me, connolly@w3.org. I also do TAG and some research stuff.

IanD: work for talis; author of Embedded RDF

Chime: working at cleveland clinic; using XML, RDF, and XSLT for clinical research data

Ben: finishing up a PhD at MIT on [mostly] unrelated stuff. more relevant to this group, I chair the RDF/XHTML task force, where we're developing RDFa, which is closely related

Rachael: working on imaging technologies in Citigroup.

Fabien: I'm researcher at INRIA in France... knowledge representation, conceptual graphs. We've been looking at RDF in wikis.

DannyA: I'm a freelance developer/writer, mostly in semantic web stuff. I'm quite interested in Atom and microformats; interested to see where this GRDDL stuff goes

Harry: I'm your chair; working at Univ. Edinburgh with Henry Thompson... interesting in XML mapping

Brian: I've been working on microformats; I developed the XSLT to convert hCard to vCard, bit it could be converted to RDF just as well

Finding Best Time for Re-occuring Meetings

HH asks about this time (1930Z) vs 3 hours earlier (1630Z)

<HarryH> Conflict 3 hours earlier

scribe: vs 4 hours earlier (1530Z)

<HarryH> No objections?

Wednesday, August 16, 2006 at 15:00:00 UTC time

Chicago * Wed 10:00 AM

PROPOSED: to meet again Weds, August 16, 2006 at 15:00:00 UTC time

so RESOLVED.

HH: so let's try this for a week and see if it sticks as the regular time

Concerns and issues with GRDDL submission

<Zakim> DanC, you wanted to note a list of issues in the author's draft http://www.w3.org/2004/01/rdxh/spec

DanC: The current spec is a mix of teaching document and specification. Many times I have had people read the document and yet not understand various parts of GRDDL, so it's evidently not very well presented. Perhaps better to have separate specification and Primer?

IanD: Different sections for implementers and authors, perhaps...

<iand> http://www.w3.org/2003/g/data-view

<iand> the document at that uri is more like what I imagine the author part of the spec to be

DannyA: how about just one document?

Danc: well, we need one in /TR/ and I'd like the namespace/profile document to stay at http://www.w3.org/2003/g/data-view

IanD: the profile document can reuse content from the specification

DanC: yes, that seems ideal

Brainstorming and solidifying use-cases

Chime: a use case: extracting RDF from XForms [?]
... e.g. a guy building an XForm thing to edit data on his weblog engine
... so data like media types, posting address, etc. can be extracted from the XForm
... see also Baker's RDF Forms

<chimezie> xforms:submission documentation http://www.w3.org/TR/xforms/slice3.html#structure-model-submission

-> http://lists.w3.org/Archives/Public/public-grddl-wg/2006Jul/0014.html * Re: use case: semantic wikis (some pointers) Fabien

Fabien: we've been looking at encoding wiki structure in RDF. tagging, too.
... we're using XHTML with RDFa to persist the data

(DanC hopes wikipedia will go this way)

<FabienGandon> SweetWiki (http://www-sop.inria.fr/acacia/soft/sweetwiki.html ) is a wiki that stores its pages directly in XHTML and RDF annotations are used to represent the wiki structure and are embedded in the wiki pages themselves using the RDFa ( http://www.w3.org/2001/sw/BestPractices/HTML/2005-rdfa-syntax ). This embedded RDF is extracted using a GRDDL XSLT stylesheet to provide semantic annotations dir

<FabienGandon> ectly to the semantic search engine. Therefore, if someone sends a wiki page to someone else the annotations follow it, and if an application crawls the wiki site it can extract the metadata and reuse them. The RDF structure allows refactoring the wiki structure by editing the RDF annotations and the RDFS schemas they are based on it.

Danny: consider somebody buying a guitar...
... suppose there's a service with aggregated instrument review data...
... the data could be aggregated from microformatted data using GRDDL
... using hReview
... you might be able to mix with hCards of your contacts
... and the aggregator should offer a SPARQL interface too
... this raises the issue that profile URIs aren't widely deployed in microformat documents

<iand> sparql querying of html pages: http://xmlarmyknife.org/blog/archives/000285.html

<briansuda> http://kitchen.technorati.com/review/search/

IanD: a couple use cases: (1) using SPARQL to query HTML pages; cf work by Leigh Dodds [sp?]

<Zakim> DanC, you wanted to note our publication obligation and my hope to use a tutorial/use case document to meet it

-> http://lists.w3.org/Archives/Public/www-archive/2006Aug/0010.html W3C Heartbeat requirement in SPARQL Bjoern Hoehrmann (Wednesday, 9 August)

http://www.w3.org/2001/sw/grddl-wg/weekly-agenda

There was some discussion of using the ESW wiki, and setting expecatations appropriately.

<iand> http://esw.w3.org/topic/GrddlResources

<iand> http://esw.w3.org/topic/MicroModels

I see http://esw.w3.org/topic/MicroModels

ah... there's the one I was looking for http://esw.w3.org/topic/EmbeddingRDFinHTML

<Zakim> benadida, you wanted to bring up the use case of outputing RDFa from GRDDL

BenA: another use case: putting the RDF inline, so you get, for example, a calendar icon next to calendar items...
... one way to do that would be if GRDDL transformations would output XHTML with RDFa
... suppose I want just one meeting from a schedule of meetings; this suggests a way to get the RDF data that corresponds to just one part of the page.

Editorial work, short term assignments

<Zakim> FabienGandon, you wanted to ask if we will have three docs: a scenario gallery, a primer and a a tech spec.

Fabien offered to do some writing [missed which part]

was Chime the 2nd offer?

Ian Davis offered to help re-structuring

<HarryH> HarryH: Fabien offered to help with use-case gallery and primer

<HarryH> HarryH: Chime offered to help use case and primer as well.

<HarryH> HarryH: DanC fine with continuing to be lead on tech specs.

Fabien: the SemWeb Best Practices WG, we had an applications/demos task force task forces.. using DOAP. Should se use DOAP/hDOAP in our use cases?

DanC: that would make sense in some cases

Harry: the microformat use cases are interesting to me too; I'm interested to work on those
