  2. TB will attend, but not Monday.


SW: Please send email reviews to list to drive the agenda.
IJ: Will we talk about formal model be part of mtg agenda?
TBray: You need to sell this first. Are you planning for this to appear in the appendix?
IJ: Ideally, yes.
TBray: Then you're going to have to sell it. Secondly, we'd need some toolware. We'd need discussion on what the benefits are. Also, the priority is to go to last call; I'd be nervous about introducing a major element so late.

IJ: I will see to it that the diagram gets done before the ftf meeting.

  1. Review of 3023-related actions
  2. Review of Architecture Document writing assignments

2.1 Review of 3023-related actions

Action CL 2003/10/27: Draft XML mime type thingy with Murata-san.


CL: Murata-san indicated that he would work on a revision. There was some discussion about where this should take place (presumably IETF process). The bone of contention is around charset. We are working on reaching consensus around that.
TBray: I think fragments are the big bone of contention. Plus you have to coordinate with XML Core.
[CL discusses various issues regarding handling of fragments.]
TBray: I would expect you have work for a few months.
SW: Any strong prefs on where discussed?
CL, TB: I'm ok with ietf-xml-mime.
SW: Me too
CL: I'd like to keep the TAG in the loop.
TBray: I'm on the list, too. The more we have to deal with fragments, the longer this will take.

Completed actions 2003/10/08:

  1. NW to liaise with Paul Grosso and the XML Core WG
  2. TBL and DC to liaise with the IETF regarding obsoleting RFC 3023.
  3. TB to talk to authors of 3023 about inclusion as appendix in xml 1.1.

Open action 2003/10/08:

  1. TBL and DC will talk to the Architecture Domain Lead.

2.2 Review of Architecture Document writing assignments

Comments on 27 Oct 2003 WD of the Arch Doc?

Recent action items:

  1. Completed action TB 2003/10/08: Write up a paragraph for section 3 on syntax-based interoperability. (done). See also comments from Mike Champion.

    TB: I'd be more comfortable with DC's two-paragraph text than what's in 27 Oct draft.
    CL: Syntax is a major contributor to interoperability, not sufficient of itself.

  2. Completed action TB 2003/10/08: Write a paragraph of rationale for why error handling good in the context of the Web. (done)
    TB: I am troubled that we lost a statement that one reason the web works well is that error handling was part of web from early on. Say that "Our experience shows that specified error handling has enabled the Web to grow."
  3. Completed action TB 2003/10/08: Propose a revised paragraph to replace the "Furthermore" sentence in section 2.3 (done)
    TB: I'm OK with Ian's handling of my text
  1. Completed action IJ 2003/10/08: Add ed note to abstract that the abstract will be rewritten.
  2. Action IJ 2003/10/08: Starting from DO's diagram, create a diagram where the relationships and terms are linked back to the context where defined. Ensure that the relationships are in fact used in the narrative; any gaps identified? With DO, work on term relationship diagram.
  3. Completed action IJ 2003/10/08: Draft good practice note for 4.4.
  4. Completed action IJ 2003/10/08: In 2.4, add story that shows how two classes of error can arise (inconsistency v. no frag id semantics defined). Frame story in terms of secondary resources.
  5. Completed action IJ 2003/10/08: Split persistency section into two and move http redirection para there, with appropriate rewrites.
  6. Completed action IJ 2003/10/08: Update OWL ref since in CR
  7. Completed action IJ 2003/10/08: Add a future work section for identifiers that the TAG expects to summarize various URI schemes and what agents can infer from the scheme.
  1. Completed action DO,NW 2003/10/08: Make the summary to replace 4.5 Extensibility and Versioning in the arch doc (done).
  1. Action CL 2003/07/21: Discuss and propose improved wording of language regarding SVG spec in bulleted list in 2.5.1.
  1. Completed action NW 2003/10/08: Write up text on information hiding/abstraction respect for before 2/3/4. (done)
  2. Action NW 2003/10/08: Revise QName finding. We will also add those two good practice notes to section 2:
    1. If you use Qnames, provide a mapping to URIs.
    2. Don't define an attribute that can take either a URI or a Qname since they are not syntactically distinguishable."

    NW: I expect I'll revise the finding some time today.

  3. Completed action NW 2003/10/08: Rewrite the last paragraph of 4.9.2 to be less inflammatory about DTDs (done)
  4. Completed action NW 2003/10/08: Massage three paragraphs following good practice note about persistency at beginning of 2.6. (done)
  1. Action RF 2003/10/08: Explain "identifies" in RFC 2396.

    RF: I'm working on that this week.

  1. Action TBL 2003/07/14: Suggest changes to section about extensibility related to "when to tunnel".
  1. Action DC 2003/07/21: Propose language for section 2.8.5 showing examples of freenet and other systems. Progress; see URISchemes/freenet

2.3 XML Versioning

Current draft is 3 Oct 2003 finding

  1. Proposed: Add an issue to the TAG issues list: XMLVersioning-41 to help track this.
  2. Publication of which draft as draft finding?


NW: There's been discussion, pushback on certain sections. I've been working on terminology and definitions. I am starting to feel like we should either get more feedback or put into arch doc to review in situ.
SW: I sent comments to NW and DO (off list)
I thought the latest plan was to incorporate the latest version (which norm sent out last week) into the arch doc as-is...
TBray: It's really long; it would increase the arch doc by 25%.
NW: At this point, I would appreciate a fresh set of eyeballs to cut it down.
TBray: I can't take a position on inclusion until I've read it.
I'll point out that about 1/8 is overhead for boilerplate, abstract, etc.
IJ: I can read it. I also propose to write a precis of 4-5 paragraphs for inclusion in the arch doc.
[Support for that proposal.]
IJ: I will liaise with DO on this, of course.
NW: I won't have time to revise finding before ftf meeting.
DO: Are concerns about lengthy material (1) hard to read (2) adds too much late in the game (3) needs editing.

TBray: I think that this text goes into much more detail than other parts of the arch doc. The question is whether the proposed text is too heavy. I need to review it before making more comments.

NW: I'm willing to help IJ work on reducing amount of text.
DO: I want to push back on removing some of the good practices. I think they are all worthwhile; some editing may be appropriate.
Action IJ: Review XML Versioning text, propose a shortened form to DO and NW for their consideration, including good practice notes.
Resolved: Add an issue to the TAG issues list: XMLVersioning-41 to help track

Action IJ: Add this issue to TAG issues list.

DO: Can we do a quickie update of the status section that our thinking may have changed?

NW: I can do a properly dated finding out with some status info.

IJ: Please chat with me about URIs.

2.4 Syntax-based interoperability

  1. Long thread starting with proposal from TB
  2. See tentative text in section 1.2.4 of 27 Oct draft. Needs review
