Hi All,
As discussed on the yesterday's call, I committed to CVS the WARP spec with the section about local network (required for UPnP use cases) at:
http://dev.w3.org/2006/waf/widgets-access-upnp/
Handling of local network is based on my proposal from [1].
Thanks,
Marcin

AB: let's make sure we are all on the same page re these comments
... what's the plan to populate the CT doc?
MC: I'll start tomorrow
... Benoit's is open
<scribe> ACTION: benoit close the loop on your P&C comment [recorded
in [23]http://www.w3.org/2009/11/19-wam-minutes.html#action01]
<trackbot> Created ACTION-458 - Close the loop on your P&C comment
[on Benoit Suzanne - due 2009-11-26].
AB: it appears Ola is OK with your response Marcos?
MC: yes
AB: we need closure on Scott's comment
<scribe> ACTION: wilson close the loop on the author element
discussion [recorded in
[24]http://www.w3.org/2009/11/19-wam-minutes.html#action02]
<trackbot> Sorry, amibiguous username (more than one match) - wilson
<trackbot> Try using a different identifier, such as family name or
username (eg. awilson2, swilson3, ChrisWilson)

AB: Scott proposes support for multipe authors?
MC: no, he was just asking how to do that
... I don't think it was a spec comment
<scribe> ACTION: marcos seek clarification with Scott Wilson re his
intent for multiple authors [recorded in
[26]http://www.w3.org/2009/11/19-wam-minutes.html#action03]
<trackbot> Created ACTION-459 - Seek clarification with Scott Wilson
re his intent for multiple authors [on Marcos Caceres - due
2009-11-26].
AB: re Marcin, his comment #1 was bug fixes and editorial, right?
MC: yes
MH: yes
AB: then we have closure on that
... what about MH comment #2?
MC: param ambiguity at the end of a mime type decl
... e.g. charset
... can also use <content> to declare mime type
... not sure which one wins
AB: will this require a new LC to fix?
MC: it should not
... break any impls
... I've clarified the behavior
MH: I don't think we need another LC
... I do think it is a bug
... I think we can resolve this over email shortly
... think the registration is also a bit buggy
<Marcos> 1. kill the parameter bit - using the ABNF you suggest
below.
<Marcos> 2. say that it is allowed, but left up to the
implementation.
<Marcos> 3. say that parameter is allowed, but if it includes an
encoding
<Marcos> parameter, then @encoding beats it (or the other way
around).
AB: does anyone have any additional comments on MH's comments?
<Marcos> <content src = "start.php"
<Marcos> type = "text/html;charset=Windows-1252"
<Marcos> encoding = "ISO-8859-1" />
AB: is the WG being asked to choose one of these opts?
RB: I think #3 is the most logical
MC: yes, I agree with #3
<marcin> +1 for 3, but I - as author - would be kind of crazy
putting two different values there :). Maybe I would like to crack
the WUA?
AB: any other opinions?
... I think we need some time to review the proposals
... not sure we can agree on this call
Arve: agree we need some time
... what are the security implications of these opts?
MH: think we should continue on email
RB: don't think we are adding new security concerns (that are
already there)
... I don't think this is a big issue
... want to decide now
AB: I heard MC, MH and RB voice support for #3
Arve: if I have to choose now, I'd say #3
DS: no opinion
AB: is #3 a bug fix or a substantive change
... I'm hearing that MH, MC, and RB say it is a bug fix
... is that correct?
<marcin> yes
MC: yes
RB: yes
MH: yes
DS: would it change impls?
MC: no, don't think so
DS: based on MC's description, this would be a class #2 change thus
would not require going back to LC
AB: draft proposal to accept proposal #3 above
... any objections?
[ None ]
RESOLUTION: group agrees to proposal #3 in MC's response to MH's
comment #2 email re P&C LC#3
AB: are there any other LC#3 comments?
MC: there is something else in MH's email
... re references to media type RFCs
MH: W3C media type reg says use RFC 2046 should be used for regis
... but 2046 says use 2048
... I think this is a W3C and IETF process issue
MC: let's see what IETF says about our registration
AB: are there any other comments from MH we need to discuss today?
MC: our use of SNIFF spec is questioned by MH
... I think we are using it OK
... but need to hear from Marcin
AB: Marcin, can we live with what is in the spec now?
MH: yes
... SNIFF spec is still a WIP
MC: my proposal is to work with Adam Barth to make sure we are
aligned with SNIFF
... on the P&C side, I don't think the proc model will change
MH: yes, I agree
... we may need to ask Adam to make some changes/additions
AB: any other issues from Marcin?
MC: no
MH: no
AB: you two, MC and MH, please get closure on your emails so we have
public record of agreement
MC: I've already changed to the spec
<Marcos> [27]http://dev.w3.org/2006/waf/widgets/
[27] http://dev.w3.org/2006/waf/widgets/
AB: anything else re LC#3 comments?
... the deadline is today
P&C spec: CfC to publish CR#2
AB: on November 23 we have a call scheduled with the Director but
that will be postponed if comments/issues are still open.
... I think we the best we can do now is to record a resolution to
publish CR but with a proviso
... Proposed Resolution: the group agrees to publish CR#2 of the P&C
spec provided no substantive and unresolved issues are raised on Nov
19
... any comments?
MC: we've addressed all comments submitted
... we have made no substantive changes since LC#3 was published
... think we are ready to go to CR
RB: I agree with Marcos
AB: anyone else have comments on CR#2 readiness?
... any objections to the proposed resolution above?
[ None ]
RESOLUTION: the group agrees to publish CR#2 of the P&C spec
provided no substantive and unresolved issues are raised on Nov 19
WARP spec: Patent exclusions by Apple ; PAG & Next steps ..
AB: last week Apple excluded two of the patent applications from the
W3C's Royalty-Free Licensing Requirements for the WARP spec (
[28]http://www.w3.org/2004/01/pp-impl/p73 )
... this presumably means a new PAG will be created
... Doug and/or Steven, do you have any information to share?
[28] http://www.w3.org/2004/01/pp-impl/p73
SP: PLH will talk to Rigo today; want to start the PAG in about
1-weeks time
AB: wow; that would be excellent
RB: indeed
DR: these are patent applications, not patents
... anyone can go to USPTO and present prior art
DS: does anyone know if there is precedence for excluding patent
apps
AB: I am not aware of that, in the context of patent apps
DS: wondering if one could take someone to court for infringing on a
patent app
<scribe> ACTION: doug I will follow-up with the IE we had for the
Updates PAG [recorded in
[29]http://www.w3.org/2009/11/19-wam-minutes.html#action04]
<trackbot> Created ACTION-460 - I will follow-up with the IE we had
for the Updates PAG [on Doug Schepers - due 2009-11-26].
AB: Rigo reported to me "Participants in the Webapps WG are free to
contact the USPTO to oppose the application if they are aware of
prior art."
... as we already know, we may continue to work on the WARP spec
i.e. work do not need to pause nor stop our work on WARP
RB: I think we should insist on continuing
DS: re USPTO, does it have to be prior art or can "obvious" be
included
DR: need to ask Rigo
AB: thanks DS and SP for your info
WARP spec: comments
AB: several discussion re WARP are continuing on the mail list:
Robin (
[30]http://lists.w3.org/Archives/Public/public-webapps/2009OctDec/07
45.html ) and Bryan (
[31]http://lists.w3.org/Archives/Public/public-webapps/2009OctDec/07
57.html ).
... and yesterday, RIM started a new thread (
[32]http://lists.w3.org/Archives/Public/public-webapps/2009OctDec/07
74.html ). Implementing that proposal could affect the P&C such that
a new LC would need to be published.
... my short summary re WARP is the main tension is if the
intentionally simplistic model as reflected in the latest ED (
[33]http://dev.w3.org/2006/waf/widgets-access/ ) is sufficient or do
we accept some set of the additional features/proposals e.g. UPnP
addresses, RIM's proposal, Bryan's proposal, etc.
... an additional consideration is, given related patents in this
area, is it wise to increase the scope and hence attack surface for
"non-friendly" patents.

[33] http://dev.w3.org/2006/waf/widgets-access/
MH: re UPnP, I think it needs to be addressed
... it would be bad to exclude the UPnP use cases
... if we don't address these UCs, the spec is dead for UPnP usage
... the WARP spec could say local net traffic is out of scope;
doesn't say it is excluded though
<Zakim> darobin, you wanted to propose a general approach
AB: MH says UPnP needs to be supported
... what do others think?
RB: I think the door for new features is already closed
... a lot of people like JIL are waiting for it
... I propose no new features for WARP
... we can make some changes e.g. some refinements
... If there is a need for additional features, they can be done in
a branched spec e.g. WARP 2.0
SC: being a newcomer, I'm not sure about the scope
... we think it is vauable to have our proposed feature in the
standard
... don't feel too strongly about 1.0 vs 2.0
... we should try to address the high priority features
RB: I'm fine with the new features, just want them in 2.0
SC: what is the impact on the features being added
... will it really add a bunch of time versus starting with a new
2.0 spec
... concerned about the review cycles
RB: can get a 2.0 spec started rather quickly
SC: I think what I proposed is useful
RB: would you be willing to edit 2.0 spec if group agrees?
SC: I'd consider it
... If we want new features, then we need to assign an Editor?
RB: yes
AB: yes, that is the case
MH: re UPnP, I proposed a special value of local
... I also proposed that local nets are out of the scope
<Marcos> +q
MH: I don't think there any objections to my local networks proposal
... think the BBC use case should be in 1.0
<arve> what about the current incarnation _prevents_ uPnP from
working?
RB: I think it should be in a separate spec
MC: the main use case is using HTTP to get stuff from the web
... My proposal is we create a new Doc like "widget access for UPnP"
<darobin> +1 to WARP4U
MC: and we do something like that for other protocols
<Suresh> If we are talking about just a few weeks or so and see good
use cases, I would encourage inluding the new features in 1.0
Arve: I agree with MC
... UPnP belongs in a separate spec
... there a other things to consider re UPnP in the context of
widgets
... think UPnP needs its own spec
AB: MH, are you interested in driving a UPnP + WARP spec?
MH: maybe; but think WARP should explicitly say UPnP is out of scope
Arve: but there's a bunch of stuff out of scope
AB: we could add a ref to a WARP4U spec
Arve: would that require a re-charter?
AB: I had not thought about the Charter implications; good point;
... that is something we need to consider
<arve> [Clarification: we need to consider whether re-chartering is
necessary, I'm not saying it is so]
SC: if there is a way to proceed without changing the Charter and
referencing Editor's Drafts even if informative, seems like a good
way forward
<darobin> RB: I don't think it would imply a re-charter
<darobin> MH: me neither
SC: want to make sure though that we can get things out quickly
DS: what is the time scale for WARP v2?
RB: as soon as an ED is ready
AB: first need to know if anyone is willing to commit to driving a
WARP4U spec
DS: we will re-Charter in June
... but may need to re-Charter earlier
... and at that time, could add the UPnP+WARP then
... but the work could proceed before the Charter
<Marcos> AB: lots of poeple agreed in the summer that we are feature
complete
<Marcos> AB: the market is adopting our specs already
<Marcos> AB: we agree that that new features are important but
should be added to a new docuemnt
<Marcos> AB: To have new features
<darobin> AB: in order for us to go down the path of a new spec, we
need an editor
SC: what is the next pub plan for WARP?
RB: LC#2
<Marcos> SC: can we have a summary?
<Marcos> SC: I might be able to commit
<Marcos> SC: I have a question. Right now it's an editor's draft?
<Marcos> DB: it's in last call
<Marcos> SC: it it progressing to CR
AB: yes, that's correct
SC: I'm willing to take an approach where we create new Drafts for
new Features
<Suresh> and having informative references from the WARP 1.0
MH: I already proposed text to handle local traffic
... I could put that in a new ED
... and then ED I create WARP4U
... could then in WARP spec, refer to WARP4U
RB: ok, we could do that i.e. add an Informative Ref to WARP4U
if/when it exists
MH: that's not acceptable
... want to have an explicit statement that UPnP is not in scope for
WARP and it is defined in WARP4U
... I can create an ED of WARP4U
... let's discuss over e-mail
RB: need to discuss Bryan's email
<darobin> RB: we should discuss Bryan's suggestion that by default
instead of excluding everything we should allow the same sutff that
browsers do, e.g. images from anywhere
RB: if we do what browsers do, we don't need WARP at all
... but I don't think that's what people want
MC: we do need it for cross-origin access because a widget doesn't
have an orgin like a browser's web page
... HTML5 defines behavior if have HTTP origin but is silent on
Widget origin
RB: that would require a bunch of mapping
MC: right; that's why we have the WARP spec
RB: need to be careful with white-lists
<Suresh> WARP = whitelist,
MC: need to align with Web security model
AB: have recent changes been made?
RB: not since the call for review
... propose we reject Bryan's proposal and move to LC#2
AB: any comments on Robin's proposal?
RB: if someone wants to implement BS' model, they could define it in
a new spec
SC: do we need a resolution on how to handle new features via new
specs?
... I get the sense new features aren't acceptable
... Given this, should we capture the process for new features e.g.
as a resolution?
RB: I'm OK with that
... but would be concerned about adding Informative Refs to the new
drafts
SC: right, Informative for now but eventually could become Normative
... would like a resolution
AB: draft resolution: new features for WARP will be handled via new
documents
<darobin> +1
<marcin> -1 for this text, refinement is needed
<Suresh> new features for WARP will be handled via new documents
SC: want to add something about references
<Suresh> New features for WARP will be handled via new documents and
informatively referenced from WARP 1.0
AB: any objections to SC's modified resolution?
RB: yes, want to say "Informatively Referenced when the docs are
published"
AB: IOW, FPWD is an entrance block
... SC, is that qualification acceptable?
<marcin> this delays the other specs allowing WARP to block the
other texts
<marcin> therefore the scope of WARP must be precisely defined
SC: so EDs cannot be referenced?
RB: they shouldn't be
DS: that's not true
RB: well, I think they shouldn't be
SC: I want to address the LC comments and keep the work going
<Marcos> -q
RB: I can live with Informative refs to EDs if the group agrees to
move those specs fwd
<marcin> it is still not clear what the relation is between WARP and
the other texts
AB: the maturity level for Informative refs is quite low, correct
Doug?
DS: yes
AB: proposed resolution: New features for WARP will be handled via
new documents and informatively referenced from WARP 1.0
RB: that's OK "as long as the group agrees they are mature enough"
AB: any objections?
<Suresh> world is not perfect:-)
MH: yes
... unclear about relationship to WARP and new text
RB: that's up to the new spec
MH: WARP must state what it is about
AB: what specifically do you object to re the wording of the
proposed resolution
MH: I object because you think UPnP must be part of WARP 1.0
... no, that's not quite right
Arve: I do not think we have agreement yet on the definition of
"local"
BS: may be able to find a defn in UPnP
Arve: UPnP's defn of local is only good for IPv4
... thus we don't have agreement on local
AB: unable to reach consensus; must stop for today
URI Scheme spec
AB: earlier today Robin began responding to Larry Masinter's
comments (
[34]http://lists.w3.org/Archives/Public/public-webapps/2009OctDec/01
31.html ) . I believe LM was only person to submit comments for the
LC ( [35]http://www.w3.org/TR/2009/WD-widgets-uri-20091008/ ).

[35] http://www.w3.org/TR/2009/WD-widgets-uri-20091008/
AOB
RB: I want to start a CfC on WARP LC#2
AB: I think we need to try again to get consensus before we make a
CfC for LC#2
... Next call will be December 3 - NO CALL ON NOVEMBER 26!
... meeting adjourned
... please continue WARP discussions on the mail list
