Convene
noah: I am probably not available next week
Ashok: could you create the agenda?
<masinter> i volunteer to chair if Noah can't make it
Ashok: I could then chair if you weren't available
noah: the meeting will be going ahead 10th May
Approve minutes of prior meeting(s)

[11] http://www.w3.org/2001/tag/2012/04/26-minutes
noah: these are noted as being a draft
masinter: I was using the minutes as a privacy example
noah: Larry, please look at actual text if you want it to be
changed
masinter: that text is fine
<masinter> did anyone else care?
<noah> ACTION: Noah to put health warning in "Booth Script" for
formatting minutes [recorded in
[12]http://www.w3.org/2001/tag/2012/05/03-minutes#action01]
[12] http://www.w3.org/2001/tag/2012/05/03-minutes#action01
<trackbot> Created ACTION-703 - Put health warning in "Booth
Script" for formatting minutes [on Noah Mendelsohn - due
2012-05-10].
RESOLUTION: Minutes of 2012-04-26 --
[13]http://www.w3.org/2001/tag/2012/04/26-minutes -- are
approved
[13] http://www.w3.org/2001/tag/2012/04/26-minutes
<jar> as a use case, the interesting thing is what the health
warning should say, to set an example for other health warnings
<jar> based on what I know of TAMI etc. I think it could say a
different thing; will follow up in email
Administrative items
noah: we should review the DANE work
<masinter> i've been talking to Philip Hallem-Baker (sp?)
noah: Larry had suggested getting invited experts
masinter: I've been talking to Philip, who has a paper on an
alternative method, and is critical of DANE
noah: we'd need someone in addition to him, to be an advocate
for DANE, right?
... Larry, would you sort out who should come and talk to us?
masinter: yes
Ashok: I've been following this, and it's still ongoing
... it looks like there's hardly any agreement on direction
... I'm wondering if it's too early to look at this
<masinter> push date of action-697 out a couple more weeks
<jar> action-697 due 2012-05-16
<trackbot> ACTION-697 prepare overview of DANE for TAG
consideration due date now 2012-05-16
masinter: it is early to come to conclusions
... but even so, if it's chaos it's not unreasonable for us to
see if we could contribute to resolving it
Ashok: then you would ask a couple of people?
masinter: yes, I think so, I haven't yet understood enough to
know how to bring it to the TAG
... so let's (Ashok and I) meet this week and see if we can
make sense of it together
Ashok: ok
noah: ok, Larry will take next step with ACTION-697
Close pending Actions without discussion
noah: ACTION-636
<masinter> I did move the document I was working on to the WIki
noah: updating product page which closes out Mime and the Web
work for now
no objections
agreed noah can close ACTION-636
<noah> ACTION-670?
<trackbot> ACTION-670 -- Noah Mendelsohn to update product
priority list to mark MIMEWeb completed after final product
page available -- due 2012-05-08 -- OPEN

gs-06
[16] http://tools.ietf.org/html/draft-ietf-appsawg-media-type-regs-06
<masinter> i think -06 made changes in response to our comments
masinter: I think they have responded to our comments
... the changes between -05 and -06 were the edits in response
to our suggestions
<noah> Could we briefly list the things they did in response to
our requests?
masinter: we need to publish Jeni's document as an RFC or an
Architectural Recommendation on best practices for media type
registrations
noah: this (media type regs) is a IETF document that will
become a RFC or BCP, right?
masinter: yes, right
noah: do we need to do something else?
masinter: we started on best practices to fragment identifiers
... we wanted them to refer to that normatively, but there
wasn't time
... but we still need to finish that document
<noah> ACTION-690?
<trackbot> ACTION-690 -- Jeni Tennison to sort next steps on
Fragment Identifiers and Mime Types -- due 2012-04-17 -- OPEN
<trackbot>
[17]http://www.w3.org/2001/tag/group/track/actions/690
[17] http://www.w3.org/2001/tag/group/track/actions/690
noah: right
... Jeni has the action on what we should do
masinter: my opinion is we should finish it
<masinter> and get it published as an architectural
recommendation or else an IETF BCP
<masinter> i also had two other items with regard to media
types which aren't currently covered
<masinter> a) file extensions, which *are* a part of web
architecture, mentioned in MIME reigistrations, but the
registration process isnt currently useful
<masinter> b) 'magic numbers', since sniffing is part of web
architecture, but the MIME registry of magic numbers isn't
JeniT: The discussion for item 6 on the agenda is about how to
take that forward, and what its scope should be.
... I think at present it's got description, but the "best
practices" aren't pitched right.
... I was going to propose to refocus on what should be put
into mime type registrations relating especially to fragment
identifiers
<Zakim> ht, you wanted to say yes, but don't lose back-story
noah: ok, let's talk about TAG work, and then jump back to mime
draft
ht: yes, I think what Jeni volunteered to do would be great
... but don't lose the back story, put it in another document
and reference it from the Best Practices document
noah: I agree, keeping the back story is good
<masinter> i would be glad to help
noah: Do we need to set priorities relative your other work,
Jeni?
JeniT: How to prioritize relative to copyright and linking
<jar> copyright + linking more important
masinter: they're both important, I'm willing to help on mime
draft, but I'll want direction
ht: since Ned won't reference the fragment identifier document,
it takes the time pressure off
noah: he's reluctant to reference it because it's not there
<masinter> what's the shortest time we could publish this?
noah: the more we do things slowly, the more we're not good
partners
... this feels like something we could get something concrete
out rapidly
<masinter> I think the fragment identifier document is nearly
done
<ht> I'm OK either way
JeniT: feels to me like we could do something moderately
rapidly, good timing with media type reg. document
noah: any objections?
<Ashok> +1
noah: none heard, so do fragid / media type higher priority
... please bring product pages up to date
... especially if I can put it in the report
JeniT: I will try to do that in next couple of days
masinter: do we need to push back on media fragments group?
... at the web conference, I talked to Thomas, and they were
saying it was a mistake when the group was chartered
... we have a draft from a WG that the folks from the IETF
thought was laughable
... there's a disconnect there
noah: what's the concern with what they've done?
masinter: they propose that fragids have a meaning that applies
to all registrations of a top-level type
... and that idea doesn't jibe with the folks who run the media
type registries, and what they could enforce
<masinter> it relates to item 7, in that if we expect all
future registrations of image/* to use the media fragments
fragmentID scheme, the mime registration document should say so
<masinter> at one point, the rtsp scheme wanted to define
fragment identifiers for URIs for that scheme
<Zakim> noah, you wanted to talk about XML vs. image
noah: we might have something to say here, which is analogous
to the generic processing debate
... we could say that there's a choice for the media type
registrations to reference that spec
... but if you do that, you can't have generic processors that
understand all images
... with XML, which is a +xml type which is slightly different,
we wanted to share specs, but also have generic processing
... with specific understanding of the subtype
... that story, that trade-off, without choosing sides, might
be useful
... to point out that if it's just buy-in of media types
one-by-one, you lose generic processing
... because other media types might choose differently
ht: Yves story as Jeni described it is not consistent with the
remarks in the current version of Jeni's document
... about the possibility of inheritance from the top
... the fact that Yves doesn't think it means that, and it's
clear that it caused an aversion reaction from the IETF
community
... I think it's worth keeping in view the possibility of
inheritance 'from the top' as in principle a coherent position
noah: it's interesting to talk about this in terms of the major
type and the +ext syntax
... certainly there's generic processing you could do on text
for example

noah: the media fragment spec made some statements about web
architecture that I found surprising
... sent in email earlier
<masinter> fragments don't have media types
noah: they said fragments have the same media type as the
original representation
... I'd welcome getting comments back on this
masinter: fragments don't have media types
<masinter> fragments aren't "retrieved"
noah: that spec says they do!
<noah> Quoting media types draft: A further requirement put on
a URI fragment is that the media type of the
<noah> retrieved fragment should be the same as the media type
of the primary
<noah> resource.
<masinter> "retrieved fragment" doesn't have a media type
<ht> Fragments _could_ have media types, if the parent media
type registration specifies that they do
noah: I agree with Larry that they don't have a media type
... it might be worth going through the spec to look at these
<masinter> we went through this with http Range
<masinter> byte range retrieval... (need to look up)
JeniT: I could have a look as part of the fragid & media type
work

noah: anything else on the media type registration draft?
masinter: there are two things in my original analysis that
aren't within this
... one is file extensions, which aren't part of the web,
they're mentioned in several specifications
<noah> What do you think we/they should say about file
extensions?
masinter: a recent thing in HTML5 in file upload that talks
about file extensions
... the media type registration lists extensions, but the lists
don't correspond to what people use
... this is a gap that neither W3C or IETF is working on
<jar> 4.12. Additional Information
<jar> SHOULD File name extension(s) commonly used on one or
more platforms to
<jar> indicate that some file contains a given media type.
<jar> (quoting the draft)
noah: do you have a concrete suggestion about what should be
done?
masinter: I've been worried about this for years, and I'm
trying to see if anyone else on the TAG is interested in
pursuing this?
<masinter> that the MIME registry for file extensions is
incomplete, not useful, etc. but W3C specs use file extensions,
and they're getting *more* used in specs
noah: it's part of the work we just closed out on Mime and the
Web
<masinter> another thing in the same category are the 'magic
numbers'
jar: is there a registry of file extensions?
masinter: there's no official registry of file extensions in
IETF or W3C
... the packaging spec includes file extensions for use within
packaged documents
<noah> (and of course, different OS's have at least somewhat
different constraints on extensions, e.g. 3 char vs unbounded.)
masinter: we have a best practice that HTTP URIs with file
extensions shouldn't mean anything
... the media type registrations should include extensions
jar: would this be an IANA considerations thing? a request to
make a registry?
masinter: we could make a registry
ht: there already is a registry, a hugely complex registry
... in linux
<masinter> there are multiple registries, apache filetypes
noah: that's not cross-OS
ht: there's an enormous degree of overlap, except with Windows
... all the unix variants buy into it, including the Macs
noah: Windows has its own, and people hack it
ht: there is a registry, it's just not an IANA one
<masinter> [22]http://filext.com/
[22] http://filext.com/
<masinter> is a web site dedicated to registering file
extension
noah: the IETF has a loose form, in that media type
registrations can list extensions
... I just wonder if they might be checked for consistency with
others
jar: that's not going to happen
noah: you mean if I gave a file extension of 'jpeg' then they
wouldn't object?
masinter: there's a website [23]http://filext.com/
[23] http://filext.com/
<noah> FILExt is a database of file extensions and the various
programs that use them. I
<masinter> i'm just pointing out that this is a part of "how
the web works" that isn't standardized, and that disagreements
about cause problems
<masinter> and that use from W3C specs is increasing
jar: the way I see these registraties is that the truth comes
from IETF and IANA just does administration
... we could under IANA considerations ask them to start
keeping a registry
... I'm not saying it's a good idea, just it might logically
make sense
... but if the information is in other places, maybe it doesn't
noah: what should we do about this as the TAG?
<masinter> put it on our list of "things we should do later" ?
masinter: maybe we need a list of things that webarch doesn't
talk about
noah: what was the other one you had, Larry?
masinter: magic numbers and sniffing
... I'm bringing these up because they are both in the media
type reg document as something you could say
jar: they have a SHOULD, you have to justify not saying them
masinter: but it doesn't tell you why you would say it, or what
the best practice is
noah: does the TAG need to engage on this?
... couldn't an individual make comments on the draft?
... what do you want them to do, and does it involve the TAG to
get there?
masinter: I see people building things that don't work well
because of inconsistencies in these areas
noah: but what should we do?
masinter: I'm ok with moving on
<masinter> I don't know what else to do with those
<masinter> At one point in an AC meeting I argued for more
"fixing the potholes" vs. "building bridges to nowhere" and
that file extensions and magic numbers are potholes in the web
architecture
<ht> For the record, [24]http://mx.gw.com/mailman/listinfo/file
is the mailing list which manages the magicnumbers/extensions
'registry'---there is no website for this, the closest there is
is the README file from the 'file' package, e.g.

Ashok: Jonathan, I have a small quibble. I'm tempted to look at
3rd row, see 1 fail, and say "ah ah". Then I go to the
proposals and see nothing matching the left hand column entry
"New status code"
jar: Good point.
... That's an omission. Wasn't formatted as a change proposal,
but we did get the proposal. I'll put on my "to do list" to
document. The proposal is for something like an HTTP 209 status
code meaning "what I'm giving you is a description, not a
representation"
<masinter> I'm still talking to jonathan about the scenarios
and the underlying assumptions that they seem to make (to me)
noah: have you got feedback on the matrix from the community?
jar: I only really asked the TAG, and haven't really got
feedback except from a couple of TAG members
Ashok: could you put in the left column a reference indicating
the section in the other document?
jar: yes, I will try
... if there are questions that people on this call have about
the matrix, this might be a time to surface them, but email
would also work
... I'm not sure how to review this
noah: ideally this should lead to making a proposal
... it might be that not all failures are equally bad for the
community
... so you might push forward to narrow discussion to just two
or three
jar: we talked about forming a task group, and one has emerged
... Henry, Jeni and I have been exchanging email for the past
couple of weeks
... we're working on a narrative for the issue behind the
scenes
... I have strong opinions about how to go at this
... I'm trying to get support from Jeni and Henry on these
ideas
... they have strong opinions too, so we're going to try to get
something between us
noah: the other thing I missed in the matrix, I wondered if
there were things that it doesn't cover
... for example, aside from use case J, I was looking for
something that would break if there was a new status code
... are all these deployable to some degree?
<masinter> "deployable" has a scope.
jar: the question is who do we give veto power to
noah: what do proxies do if they see a status code they haven't
seen before?
jar: I think it's specified in the HTTP spec
noah: doing some due diligence on what running code actually
does would be a good idea
... to see if the options are actually viable
... many of these have fallen down when we look at what ISPs
can do
jar: I don't know how to do that in the matrix
noah: I'm not saying how to format it, I'm saying do analysis
early enough
jar: almost no one will accept a new status code
noah: but why? we need to capture that
... it makes architectural sense to me, you say it fails only
one use case
Ashok: browsers would have to implement it, right?
jar: they might treat it the same as a 200
... one of the big complaints about the 303 is you have to do a
song and dance around your server configuration, and that's
what use case J is saying
... maybe we should talk about the other goal
... we have to think about how to generalise this
... if this is an RDF-specific problem, we need to hand it off
to people who care about RDF
... draw some line to say what we think is good practice
... there are some things that are TAG business, and others
that are RDF business, and a lot of the proposals look like RDF
business
... we've been talking about use case M, HTTP consistency,
which seems like a TAG issue
... I have a proposal for how to do the hand off, but I want to
wait for Henry and Jeni to agree or disagree about that
... unless we want to talk about this on the call, maybe we
should put it out to committee
Ashok: is this really a RDF problem?
jar: it depends on what you think the problem is
... to me, it's a serious issue whether HTTP and RDF diverge
... maybe it's ok if they diverge, but that suggests they
should be careful in the language they use
... so there isn't confusion about how web architecture works
Ashok: suppose we took RDF off the table, here
... what would we still have?
masinter: I don't think there would be things left
<masinter> i think this is a 'use of RDF' problem
<masinter> RDF doesn't have a problem, URIs don't have a
problem
<masinter> it's people who want to turn "statements in RDF
using URIs" into "statements about the real world" who want to
take a URI and have it identify something in the real world
<jar> absolutely
<masinter> and the problem is that URIs were never intended as
a general mechanism for identifying things in the real world
ht: there definitely would
... there are definitely things left that would matter
... the language that the TAG and TAG members such as TimBL
have used for years
... is self-contradictory
... if we care about clearing up a mess that we created, we
have to fix that
... and that would be true even if RDF didn't exist
noah: I think on general principles, and given the TAG had this
resolution years ago
... I think it would be helpful to explain why it's not our
business, if it isn't
... for example, Larry and I didnt immedately agree about what
HTTP status codes are used for
... explaining what that answer is is very much in TAG's scope
... especially as our last solution was to use a status code
... I'd like to explain what the limits are of web architecture
and their applicability to this problem
<masinter> people building ontologies think an ontology is a
mechanism for turning idnetifiers for web resources into
identifiers of concepts
<ht> I also don't think we could just profer a new status code
as a solution without a story behind it
jar: it would be nice to get any bit of consensus we can on
what's TAG business and what isn't
noah: if there are useful back-channel discussions happening,
maybe we should hang loose for a while
ht: I think we have to work a bit longer towards convergence
... I'm the major bottleneck, probably, but I'd like another
week
<noah> We're hearing that Jonathan, Henry and Jeni are working
in the background to get some more clarity. Should we just hold
off a couple of weeks and await progress?
Ashok: Henry, you've spoken about the language around content
negotiation and so on being self-contradictory
... do you have an idea how to fix that?
ht: no, I don't
... I mentioned it because it's something I use to test
proposed solutions
... because I think 'it better solve this problem too'
... the cardinality problem: how many resources are there?
<Zakim> masinter, you wanted to talk about another approach
masinter: I've been trying to pursue a different direction,
where we have a mechanism for making statements in RDF
... and an implicit assumption where you can use URIs to ground
a statement in the real world
... and the problem is the nature of the grounding is ambiguous
... and we have given conflicting advice, using status codes
and so on
... the problems that we really want to talk about wrt
publishing, linking, copyright, security, trust
... are not easy to explain in a world where we presume that
there is a common understanding about how a URI identifies
something
... and if you move to a different model, where you don't think
about the truth of statement or their meaning
... as something that's disembodied from the agent that is
saying it or reading it...
... and look at a speech act model
... then you stop asking what the triple means, you look at
intention
... a speaker utters an RDF assertion using URIs, a receiver
reads an interprets it, as a speech act
... this is a different model, which is better suited to
talking about the difference between copying something and
linking to it
... that you don't try to interpret statements independently of
the context in which they are stated
... this leaves httpRange-14 behind, because we're taking on a
more complicated, less trusting model for communication
... I've been trying to think about how to express the
copyright & linking document we've been working on
... if we were stating these things in RDF
... and that gets you beyond the status code
<jar> This is the "choose based on context" proposal in the
chart
noah: how much in RDF would have to be deprecated or turned off
to use that new model?
masinter: we have systems that assume trust between
communicators
... you can't do induction unless you assume that everything is
true
noah: so all the statements from DBPedia remain equally useful
if we go down this path?
masinter: you have to put them into context that DBPedia is
using, where maybe they intended you to look at 303 codes and
maybe used something else
... it's part of a larger framework
noah: I'd be interested to see how far you could get on getting
Tim to agree to this
masinter: I think I'm making some progress on him
jar: we have to figure out what problem we're trying to solve
... we've had a hard time getting focus
... these are all fine things to work on, but it's not what we
started with
... this isn't an issue for the linked data community
masinter: I think when you get to linked data in the real world
... with government agencies publishing data
... we will need a better model
jar: but is that the TAG's problem?
... that's a problem for linked data, and they will figure it
out for themselves
... right now we're doing design for nobody if we take this on
noah: maybe if you change the ground rules, the solutions are
different
masinter: I think the question being asked isn't interesting
jar: this is why I want to get it out of the TAG
masinter: we can say we're working on something else which is
more important
<masinter> i think we should drop 'findings' more than 2 years
old if we can't bring them to community consensus
noah: we have to be careful about how we do this after 8 or 2
years
... we could look really stupid, beating our heads on this for
ages, and finally to say it's not our problem
... I would have a problem with that
... why did this appear to be a problem for so long?
... we should have figured out a long time ago that this wasn't
our problem, if it's not
... I think the answer is about how to use HTTP "properly"
... and that is the TAG's problem
timbl: sorry for arriving late
... having discussed this with jar just yesterday
... I think the hope has been, for me, that the TAG would be
able to describe an architecture that included linked data
... the original architecture didn't: it was a hypertext
system, it didn't include RDF
... the problem has been partly that there's a small overlap
between the TAG and the RDF community
... a relatively small overlap in general between linked data
and people doing things with HTTP
... I think RDF should use HTTP properly
... it may be that the niceties of how RDF works can't be
discussed with non-RDF people
... so we end up with an architecture that is consistent with
HTTP, but is more detailed and refined
noah: one of the proposals that seems to have a low number of
downsides is to use a new status code
... I would have thought that the TAG should explain whether
that's architecturally appropriate
... the RDF community might separately settle on whether they
want to do that
... do you think that's more than what the TAG should be doing?
timbl: if the TAG can solve this, great, write it up
... I regard httpRange-14 and the 303 header as a compromise
noah: we're discussing jar's matrix
... one of the proposals is to use a new status code
<jar> 207, 208, 209
<jar> refresh the page
noah: I'm just probing because you seemed to be saying the TAG
should back off because the communities were separate
... I would say the TAG has a role to play to say whether it's
an appropriate to use a status code for this
timbl: there are a lot of issues here where it's only the TAG
who are chartered to do this
... but I think it would also be reasonable to just make this
work for linked data
... if we had a new status code, we would have to explain how
to do so, maybe push towards hash more strongly
... still have to deal with simple OGP as well
... there's valuable work to be done here
noah: we're at time
... Jonathan, Henry and Jeni have been talking behind the
scenes to move towards more clarity
... I'm inclined to wait a week or two and see what happens
jar: agreed
timbl: I'd be happy to be brought up to date offline
masinter: when they come to a conclusion, they should bring it
to us

<trackbot> Created ACTION-704 - with help from Jeni and Henry
to try to identify next steps for moving forward on
httpRange-14 [on Jonathan Rees - due 2012-05-15].
masinter: come back with at most the number of rows as the
number of people in the subgroup
<masinter> I don't like any of the proposals, because I don't
like the question
<masinter> but at least if you're going to continue to ask the
same question, come back with at most N rows, where N is the
size of the subgroup
<noah> We are ADJOURNED. Informal discussion can continue.
