Thank you, John. As one who was not present at the meeting, the minutes
now seem to be very good, but of course I don't know what I'm missing. I
would prefer that someone who was there would take a look before we
approve on Thurs. Thank you in any case for the formatting corrections,
which are a significant improvment.

Convene
DC: Can you scribe next week, Henry?
HT: OK
<DanC> minutes ok? http://www.w3.org/2001/tag/2010/01/28-minutes
<DanC> "DKA: As a member of that WG, not sure I can concur "
I can't understand DKA very much at all...
<DanC> PROPOSED: to approve http://www.w3.org/2001/tag/2010/01/28-minutes
ammended to note that "DKA: As a member of that WG, not sure I can concur"
should read "DKA: As a former member..."
<DanC> DKA, is it enough to note the correction in today's minutes?
<DKA> fine
<DanC> PROPOSED: to approve http://www.w3.org/2001/tag/2010/01/28-minutes
ammended to note that "DKA: As a member of that WG, not sure I can concur"
should read "DKA: As a former member..." and to note that the security
stuff is unclear
JK: I found the 'security' section unclear
<masinter> if there are errors in the minutes, send the errors to me and
i'll update
<DKA> It should be "when I sat in on the first working group meeting as an
observer"
JK: Happy to just note that and move on
<DanC> ACTION: DanC to take approval of minutes 28 Jan offline [recorded
in http://www.w3.org/2010/02/04-tagmem-minutes.html#action01]
<trackbot> Created ACTION-385 - Take approval of minutes 28 Jan offline
[on Dan Connolly - due 2010-02-11].
TVR: Take discussion offline
ISSUE-53: ACTION-231 & ACTION-232 conneg, generic resources
<DanC> close ACTION-232
<trackbot> ACTION-232 Follow-up to Hausenblas once there's a draft of
HTTPbis which has advice on conneg closed
LM: Sent a note to requestor - should close the item
ISSUE-53: ACTION-231 & ACTION-232
LM: Propose to close the actions
HT: Why did we (re-) open this?
... Conneg text hasn't changed, has it?
LM: In editors draft
http://lists.w3.org/Archives/Public/ietf-http-wg/2010JanMar/0033.html
<DanC> I propose that HTTPbis changeset 745 section.4.p.5, along
<DanC> with the Nov 2006 finding, addresses our ISSUE-53, Generic
Resources.
<DanC> http://trac.tools.ietf.org/wg/httpbis/trac/changeset/745
<jar> ht, description of http://www.w3.org/2001/tag/group/track/issues/53

<DanC> close action-326
<trackbot> ACTION-326 track HTML WG progress on their bug 8154 on polyglot

LM: We still have an issue around polyglot documents
<masinter> agree to close action
DC: Interested in XML well-formed
HT: There might be other issues, but not under this action
ISSUE-51 & ACTION-308: Propose updates to Authoritative Metadata and
Self-Describing Web to acknowledge the reality of sniffing
JK: Ball is with the group

draft
... draft is inadequate
<masinter> http://tools.ietf.org/html/draft-abarth-mime-sniff-04
<DanC> tx
<masinter> dated January 26, 2010
<DanC> ("the issue"? which?)
HT: there is another action on sniffing not linked from the sniffing issue

<DanC> "Such 'sniffing' SHOULD NOT be done unless there is evidence that
the
<DanC> specified media type is in error"
HT: Barth said OK
HT: However, change was rejected by editor
HT: We were asked whether we co-ordinated with HTML WG
<masinter> I am considering offering to rewrite barth-mime-sniff
<DanC> action-370?
<trackbot> ACTION-370 -- Henry S. Thompson to hST to send a

<DanC> (arbitrarily; feel free to choose another date)
LM: I don't like the sniffing document
<DanC> (henry, "the rest of us liked it" doesn't speak for me)
<ht> HST would need to look at the f2f minutes

<johnk__> minutes from f2f where we created ACTION-308
<DanC> tx
LM: Notion that the file has a "correct type" is wrong
LM: You're making guesses about what the author intended
LM: language of "correctness" is wrong
<Zakim> DanC, you wanted to ask lmm about the status quo which relies on
something other than what's in the content-type header
LM: if someone tells you it's text/plain and you guess something else,
this is your peril
DC: community standard is that web content providers rely somewhat that
the consumer will consult more than content-type
LM: Not sure that's true
DC: I know they didn't consider it, but if you took it away they'll be
shocked
<jar> http://trac.tools.ietf.org/wg/httpbis/trac/ticket/155 was closed 6
months ago... adam's 1st draft was july 13 ... not clear whether the
httpwg talked about it (trying to understand whether there's new
information for httpwg)
DC: Is it more cost-effective to specify what's going on, or to move the
community away fromthis reliance?
DC: The latter seems expensive, perhaps not possible
LM: value of reverse engineering decays over time
DC: Would be happy to see an alternative draft
LM: Happy to propose alternatives
LM: Recommend that the TAG does not update our findings to reference the
current sniffing draft
LM: needs to be opt-in mech as well as uniform and secure
LM: set of criteria need to be met
<DanC> (can anybody write down the criteria lmm said?)
LM: reluctant to recommend sniffing until we have a good algorithm
LM: "fine-grained opt-in"
LM: happy to review barth sniffing draft 4 and suggest any necessary
follow-up to TAG

<trackbot> ACTION-278 Draft changes to 2.7 of Metadata in URIs to cover
the "Google Calendar" case due date now 2010-02-09
LM: Thinking about this a lot
LM: What distinguishes capability-based system and what is proposed here
is...
LM: If you have a resource, you should have just one URI
<DanC> (indeed, there's a tension with aliasing)
LM: Capability URI is not usable for an "access control system"
LM: If you combine the key with the URI, you can't do lots of things
(expire the key without expiring the URI for example)
LM: Confidential in the finding means something really quite strong
LM: Another use pattern where the information is not confidential, but not
widely known
LM: I don't really care if people can read my calendar
LM: Not really confidential
DC: No sharp distinction between that and passwords
DC: Counting on you not to pass it (password) around
LM: I can change the password without changing the calendar URI
LM It's the address as well as the capability
DC: Large random numbers can be revoked
DC: Rethink "don't make aliases"
LM: That _is_ one of the conflicts
LM: The other is that infrastructure of the web assumes it's ok to make
easily available URIs (in logs etc.)
TVR Not a useful question to answer
<Zakim> ht, you wanted to gloss larry's point as revocation is willfully
breaking a URI
HT: if you put a large random number in a uri, it says that URI identifies
a resource
HT: you shouldn't ever revoke that capability
HT:& so you can't easily say that a URI can be revoked
DC: 403/410 them, not 404
HT: It seems you're "cheating" - if you name a resource, and then remove
access to the resource at that URI
DC: I'm persuaded that capability URIs are OK...
<DanC> ("actual access control method" is needlessly pejorative...
closed-minded, even.)
<jar> lm: Three cases (a) public, (b) obscure, (c) confidential
LM: I see that use of capability URIs are for non-confidential cases
JAR: Not sure what Tyler thinks of Larry's distinction
JAR: Would like to write up the "unsubscribe" case
<raman> have a hard stop, need to bale.
DC: we did write that up
DC: GET/POST finding
ACTION-354: Client side storage APIs
<DanC> action-354?

about -- due 2010-01-21 -- PENDINGREVIEW
<trackbot> http://www.w3.org/2001/tag/group/track/actions/354
AM:AM: Two client-side storage API specs.
<DanC> TAG Action-354 Review client-side storage API’s
AM: should have a better story than "cookies"
AM: name/value pairs should be made more useful
AM: I only looked at two possible cookie storage replacements
DC: Just talking about different use-cases?
AM: there's also a caching API spec and a web storage spec.
AM: I've not yet looked at these
DC: Would like to know about all these APIs and how they compare
AM: Many documents seem to explore this client-side storage case
AM: reviewed 'index' API, 'web SQL' API
<jar> indexed api and web sql api
<johnk__> WebSQLDatabase and Indexed Database API
AM: WebSQL API is not really a spec...
AM: Based on SQLLite database

DC: Is there room in webarch for all of these?
