Metadata Architecture
<noah>
[19]http://lists.w3.org/Archives/Public/www-tag/2010Sep/0016.html
[19] http://lists.w3.org/Archives/Public/www-tag/2010Sep/0016.html
Noah: Jonathan would like to pass this on to someone else
jar: I cannot think about anything non-trivial to say ...
<jar> masinter: survey what w3c is doing?
Larry: Can we survey what W3C does about metadata and problems
thereon
Noah: Should we follow the links from the action
jar: I cannot do this ... would be better if we got some fresh eyes
looking at it
... or postpone to January
Noah: We could close it but wait till Tim is around
... or someone follow the links
<jar> agenda: [20]http://www.w3.org/2001/tag/2010/09/16-agenda
[20] http://www.w3.org/2001/tag/2010/09/16-agenda
<noah> Take a look at email:
[21]http://lists.w3.org/Archives/Public/www-tag/2009Nov/0028.html
[21] http://lists.w3.org/Archives/Public/www-tag/2009Nov/0028.html
<noah> Tracker, this discussion is about ACTION-282
Ashok: That's about metadata access ... this issue is about metadata
architecture
<noah> I think Larry is proposing: "Draft a finding on which
metadata technologies (RDFa, photo EXIF, etc.) do I use when?"
<noah> Maybe we should retitle the action?
Larry: People don't know how to write metadata ... lots of confusion
<jar> masinter: A success criterion for this activity. RDFa,
microdata, XIF, XMP, GPS, privacy policy. People are confused about
what to use when. It's a confusing mess. What happens when they
conflict? When I want to change it? Operational issues among W3C and
other specs.
<noah> NM: I think we also discovered that the advice in
[22]http://lists.w3.org/Archives/Public/www-tag/2009Nov/0028.html is
misleading; ACTION-282 is mostly NOT about metadata access.
[22] http://lists.w3.org/Archives/Public/www-tag/2009Nov/0028.html
<noah> LM: I'd like an architecture which is a framework into which
these specific mechanisms can be placed.
Larry: We need a framework into which these mechanisms can fit
jar: That matches my memory of how this came up
<noah> jar: F2F discussion would be good...we're ready
jar: Perhaps duscuss at f2f
Larry: Perhaps create an outline
noah: I can put on an agenda
Larry: May be good to have a reading list
... I will send mail
<noah> . ACTION: Noah to schedule discussion of ACTION-282, which
metadata mechanisms to use when. Get reading list from Larry and
www-tag.

Generic fragment id processing
Noah: There is inconsistency in 3023bis and frag-id processing for
RDF+XML
... disagreement about what should be done
... TAG recommended that 3023bis back off but we got strong pushback
saying that generic processing was desirable
<noah> Larry's email:
[24]http://lists.w3.org/Archives/Public/www-tag/2010Aug/0034.html
[24] http://lists.w3.org/Archives/Public/www-tag/2010Aug/0034.html
Larry: Is there usecase for putting XPointer in the frag-id?
Noah: Recaps the generic processing argument
Yves: Issue is not have XPointer supported but all media types must
have a syntax compatible with XPointer

<noah> Norm writes:
<noah> >> I find that unsatisfactory. It leaves generic XML
processors out in
<noah> >> the cold once again by expecting them to be aware of all
of the media
<noah> >> type registrations for all +xml formats.
Henry: By using +xml they buy into XML and thus folks expect XML
processing
<Zakim> noah, you wanted to go back to talking about conneg
Noah: So, people can read different documents and process the
content differently
Larry: You want frag-id processing be generic
<jar> ht, noah: the URIref 'identifies' one thing when the processor
has read the rdf+xml spec, a different thing when it reads 3023bis.
maybe that's ok?
<jar> ... a single document, same media type in both cases
<jar> masinter: I want to push back on Norm's and Roy's use cases
Larry: I want to push back on their usecases ... don't understand
why frag-id processing has to be generic
<noah> HT: XSL stylesheets that format rdf+xml
<jar> I don't buy that one. It would be meaningless (almost always)
in the RDF interpretation
<ht_home> Note that XInclude is _not_ an example, because it does
not allow the use of FragIDs
Larry: I will ask Norm or Roy for concrete example
<noah> ACTION: Larry to ask Norm, Roy and Martin for concrete use
cases where generic processing of fragment ids is important

<trackbot> Created ACTION-466 - Ask Norm, Roy and Martin for
concrete use cases where generic processing of fragment ids is
important [on Larry Masinter - due 2010-09-23].
<ht_home> jar, the example I have in mind preserves the RDF
semantics but restructures the RDF XML
<jar> grumph. need details.
AWWW and the Web interaction model
<noah> ACTION-355?
<trackbot> ACTION-355 -- John Kemp to explore the degree to which
AWWW and associated findings tell the interaction story for Web
Applications -- due 2010-06-07 -- PENDINGREVIEW
<trackbot> [29]http://www.w3.org/2001/tag/group/track/actions/355
[29] http://www.w3.org/2001/tag/group/track/actions/355
<noah> John did some writing:

[30] http://lists.w3.org/Archives/Public/www-tag/2010Jun/0034.html
Discussion of John's document
<noah> AWWW section on "Interaction":
[31]http://www.w3.org/TR/webarch/#interaction
[31] http://www.w3.org/TR/webarch/#interaction
Noah: AWWW slices into 3 themes, identification, interaction, data
formats
John: How does client know it can use a particular URI ...
client/server agreement
... update of state w/o user interaction e.g. web sockets
... need to define 'user agent' ... may be more than a browser
... acts on behalf of server also
Larry: Web apps break our model of knowledge ... downloaded code
knows stuff client does not know
... client runs downloaded code on behalf of server
<noah> Larry: what's interesting is the client is executing code not
(just) on behalf of the client, but rather downloading code that
acts on behalf of the server
<noah> I think that's a really useful way to put it.
John: Clients act like servers and servers like clients
Larry: Client has to know security boundaries not the semantics
Noah: John, can you write a document ... maybe a sketch
John: Yes
<noah> LM: Be careful about terminology about "client", "server" and
"knowing"
<noah> What I asked John to do was an early draft of either an
updated version of [32]http://www.w3.org/TR/webarch/#interaction, or
else perhaps a finding that would be the start of a complementary
section in some TAG publication.
[32] http://www.w3.org/TR/webarch/#interaction
Larry: ... only need URIs for states you need to come back to
<noah> AM: Larry, you commented on my writeup saying that, and I
agree with you. Raman came back and pushed back, but I've forgotten
what his point was.
<noah> AM: Do you know?
<noah> LM: No.
MIME and the Web
Larry: I wrote a blog post on use of MIME and how it could be
aligned better with Web Architecture.
... suggested some improvements to MIME registry
<noah> LM: Thinking of splitting into two documents.
Larry: may be easier to get agreement on status and history than the
improvements
<noah> We are discussing:
[33]http://lists.w3.org/Archives/Public/www-tag/2010Sep/0027.html
[33] http://lists.w3.org/Archives/Public/www-tag/2010Sep/0027.html
<noah> LM: Also might relate to versioning issues
Larry: also about sniffing
... probably separate versions from variants
... finally about distrbuted extensibility
... I want to bring learning from other MIME types to HTML
... Pehaps descriptive expositions of what has happened
Noah: Can you do some work on this
Larry: I will have another document in a week
