2.5 Web Architecture Document Last Call

2.5.1 Last Call Issues

Review open issues starting with nottingham1.

Chair proposes a two-pass review: first to determine if any of these issues have been overtaken by events. Then to determine which we need to resolve.

If we get through the list, we’ll go back and begin discussing the issues we selected as being on the critical path for a second Last Call draft.

[Zakim]
DanC, you wanted to speak to XML Schema action
[DanC]
DanC: I asked the XML Schema WG for telcon time; haven't heard back yet...
PaulC: shall I call the chair?
PaulC is excused to call the XML Schema WG chair for a few minutes...
----- Web Architecture Document Last Call
NW: let's continue sorting into OBE, LC-critical, open
-- nottingham1: Second bullet doesn't make sense 1.2.1. Orthogonal Specifications
NW: doesn't look OBE
... relevant text is still there, though moved
[Chris]
I agree thatperformance is the reason in practice (parsing all content to look for headers)
[DanC]
PaulC reached Ezell, who has now seen the request and intends to answer presently, after consulting some XML Schema WG members.
NW: I'd like to be available Thu, but I see that I'm not. so I still prefer Fri.
[Norm]
http://www.w3.org/2001/tag/2003/lc1209/issues.html?view=wg&closed=1&expert=1&editorial=1&clarification=1&stateAgreed=1&stateDeclined=1&stateSubsumed=1
http://www.w3.org/TR/webarch/#orthogonal-specs
perhaps
[DanC]
CL: suggest open. webarch makes a good point here.
... commentor says "it's not deployed because of performance"; perhaps so, but it's also a problem w.r.t. architecture
NW: so... nottingham1 open?
NW: so... nottingham1 open.
[Roy]
oops, was trying to say it was not a bad idea -- there is a lot more history involved
[DanC]
roy, is that re nottingham1?
[Roy]
yes
[Norm]
You've fallen off the phone, will you be able to come back, Roy?
[DanC]
do you want the TAG to discuss nottingham1 further?
[Roy]
later
[DanC]
we can stick it in LC-critical for now if you like.
i.e. schedule it for discussion later
[Chris]
we are saying that even if perfrmance was great, its still a level-breaking architecture problem
[Roy]
yes
[DanC]
ok, nottingham1 is LC-critical
-- klyne7 Use other schema than mailto as example
ACTION NW: take klyne7 as editorial.
-- klyne9: Add stronger language on not permitting unregistered URI schemes
CL: yeah... "is discouraged" isn't clear enough. "should not"
ACTION NW: treat klyne9 as editorial
PC: yeah, that text is still ther.
s/ther/there/
-- klyne12: Proposal to drop paragraph on inconsistent frag ids
http://www.w3.org/TR/webarch/#fragid
http://www.w3.org/TR/webarch/#media-type-fragid
NW: odd; greek letters are still in 3.3.1. CL: yes, see proposed text from my action. NW: good!
NW: we've re-written this; it's now in 3.3.2
(CL, you're welcome to write him individually)
NW: klyne9 is OBE.
[Chris]
yeah okay
[DanC]
NW: klyne12 is OBE. [rather than klyne9]
-- klyne17: Worth pointing out value of RDF descriptions depends on URI persistence?
CL: commentor not sure or something... NW: open, at least; we've re-written some.
NW: klyne17 open.
-- klyne20: Say something about relationship between Hypertext Web and Semantic Web?
NW: Ian 8Jun rev seems to deal with this. DC: yes, 4.6.
NW: klyne20 OBE.
-- klyne21: Add statement about scalability concerns
CL: fair point; hmm... I have an action
NW: klyne21 is LC-critical, to review CL's action
ACTION CL: Draft text to explain that there's a tradeoff in this situation. continues from 14 May 2004
-- klyne25 klyne25: Add reference to RFC3117, section 5.1?
"On the Design of Application Protocols" http://www.ietf.org/rfc/rfc3117.txt
sec 5.1 Framing and Encoding
DC: I'm interested to look at it
NW: klyne25 LC-critical.
ACTION DanC: report on study of RFC3117, section 5.1
PC: note BXXP is in the same design space as SOAP... CL: yes, there are probably lots of things written about "Why we did X with XML".
[Chris]
The pain of recreating this social infrastructure
far outweighs any benefits of devising a new representation. So, if
the "make" option is too expensive, is there something else we can
"buy" besides XML? Well, there's ASN.1/BER (just kidding).
[DanC]
-- manola17: "Agent" that includes "people" source of confusion
DC: I think this is OBE
NW: manola17 is OBE.
-- manola27: Provide examples of mistaken attempts to restrict URI usage
CL: yes, fair point... e.g. "we assume HTTP" in a format spec would be bad.
NW: manola27 is LC-critical
ACTION CL: draft example ala manola27: Provide examples of mistaken attempts to restrict URI usage
-- i18nwg5: Discussion of content-type header hint
PC: looks like nottingham1
DC/scribe: it's LC-critical.
NW: i18nwg5 is LC-critical, like nottingham1
-- i18nwg8
PC: looks worth discussion. CL: yup
RF: Ian's dealt with this, yes?
PC: yes, but let's look again.
NW: yes, let's look again
NW: i18nwg8 is LC-critical
-- i18nwg16: Good practice on URI opacity impossible to follow for humans.
[Norm]
zakim, who's talking?
[Zakim]
Norm, listening for 10 seconds I heard sound from the following: Norm (9%), Roy (9%)
[DanC]
NW: we've changed to "SHOULD NOT"... OBE?
DC: either way...
NW: i18nwg16 is OBE
-- i18nwg19: text/foo+xml considered useless?
CL notes recent Internet Draft relevant to this.
... deprecates this.
[Chris]
rfc3023 revision: http://lists.w3.org/Archives/Public/www-tag/2004Jul/0016.html
[DanC]
DC: worth reflecting in webarch? NW: I think we do already. OBE.
NW: i18nwg19 is OBE
[Chris]
http://www.ietf.org/internet-drafts/draft-murata-kohn-lilley-xml-00.txt
Major differences from [RFC3023] are deprecation of text/xml and
text/xml-external-parsed-entity, the addition of XPointer and XML
Base as fragment identifiers and base URIs, respectively.
[DanC]
-- i18nwg20
NW: hmm... same slug as 19...
CL: I can see how readers could come to wrong conclusions...
ACTION CL: propose text based on i18nwg20
NW: i18nwg20 is LC-critical
-- rosenberg3: Reuse appropriate URI schemes (and protocols)
"On the use of HTTP as a Substrate" http://rfc.net/rfc3205.html
NW: we have an issue on that...
[Roy]
/me I'll check the status of 3205 at next week's IETF
[Chris]
http://rfc.net/rfc3205.html
Says its a BCP
[DanC]
DC: ah; IJ did this.
NW: rosenberg3 is OBE
[Chris]
http://rfc.net/rfc3688.html
[DanC]
ACTION NW: incorporate reference to RFC 3688 per rosenberg
NW: and perhaps bump httpSubstrate up in priority for ftf discussion
[Chris]
If the registrant wishes to
have a URI assigned, then a URN of the form
urn:ietf:params:xml:<class>:<id>
will be assigned where <class> is the type of the document being
registered (see below). <id> is a unique id generated by the IANA
based on any means the IANA deems necessary to maintain uniqueness
and persistence.
[DanC]
-- rosenberg5: Proposed reference to IANA registry for namespaces and RFC 3688
NW: rosenberg5 is LC-critical. [cf action above]
--------- TRIAGE DONE! -------------
-- schema12: [3.6.1] [3.6.1] Good practice: Available representation. Too preferential to dereferencable URIs
DC: note telcon negotiations in progress.
