2.1 Findings, Architecture Document

See also: findings.

  1. Findings in progress:
    1. deepLinking-25
      1. TB 2002/09/09: Revise "Deep Linking" in light of 9 Sep minutes. Status of finding?

        TB: Pending; I still have to incorporate comments from people.

  2. Findings versioning
    1. SW 2002/09/09: Discuss with IJ versioning of findings. Pending. SW and IJ have discussed latest accepted v. latest draft; need to draft written proposal for TAG.
  3. Architecture document
    1. Finish discussion of feedback on arch document. Action IJ: Summarize remaining review comments:
      1. Summary of comments
      2. Comments from Graham Klyne
      3. Comments from Daniel Dardailler

      Action IJ 2002/10/17 (from Chair): Summarize these comments for the TAG.

    2. Action RF 2002/09/25: Propose a rewrite of a principle (rationale -> principle -> constraint) to see whether the TAG prefers this approach. It was suggested that the example be about HTTP/REST, as part of section 4.
    3. Action TBL 2002/09/25: Propose text on information hiding. (From 24-25 Sep TAG ftf: "The principle of information-hiding is contrary to global identifiers....Shall we put in the document something about information hiding/independent design of orthogonal specs? You should should not be able to write an xpath to peek into http headers....")
    4. Action CL 2002/09/25: Redraft section 3, incorporating CL's existing text and TB's structural proposal (see minutes of 25 Sep ftf meeting on formats).
    5. Action NW 2002/09/25: Write some text for a section on namespaces (docs at namespace URIs, use of RDDL-like thing).

2.2 xlinkScope-23

See xlinkScope-23.


TB, PC: Please wait until we comment on this before linking to it.

DC: HTML WG has no obligation to participate on www-tag. We can certainly invite them to participate as a WG. Our original email went to the HTML WG; we are awaiting a reply from the HTML WG. SW can talk to the Chair and ask for a reply; or continued discussion on www-tag.

PC: I think we need to ask whether we still hold the same opinion having seen the input. I expect this to be back on our agenda. I don't disagree with DC - getting more consolidated input on different perspectives would be useful.
TB: I'm not sure what the appropriate path forward is, process-wise.
[TAG notes that relevant threads have slowed down here and on xml-dev.]
thanks, Tim Bray, for reading all this email.
TB: I think most of the substantive talk on xml-dev was also sent to www-tag (prompted by TB).
PC: The summary should include some of what we discussed at the FTF meeting. Otherwise, the summary is disconnected.
DC: E.g., my reasons for using XLink are not in SW's summary.: PC's document ("why we decided what we did, who (dis)agrees and why") is interesting.
TB: I did this:
TB: I think that some of the rationale is in that email.
[DC notes that this is cited from SW's summary.]
PC: I think we can engage in more useful discussion and debate by demonstrating where agreement/differences are.
My position at the ftf meeting was mostly: let's share technology where we can; one linking technology is likely better than 2, unless the 1 is 1000% worse than either of the 2.
DC: I agree that PC's document would be handy.
[Support for SW adding more on TAG rationale to summary.]
IJ: These are called "findings."
DC: An interesting place to start this summary is when this was raised in the TAG. It would have been an abuse of process to squash the HLink WD. I'd like this to go back to the genesis of the issue; reported journalistic style. This started because the Director observed a disconnect; this was not at the request of the WGs involved.
TB: SW tried to cite the arguments and to summarize them. That's tricky, but if done well, that's a service to the community. Perhaps we could revise the summary along these lines:
  1. We were asked to consider this.
  2. We said yes (reference).
  3. People disagreed (references, reasons).
  4. etc.
TB: Perhaps point/counter-point can be dropped, and follow along historical lines.
DC: I'm conflicted. This was a huge time-saver. I think the summary is interesting of the discussion (even if not connected to our decision). It would be a shame to lose what SW has done.
TB: The imposition of point/counter-point approach might grate some. But I would be satisfied with SW approach and more connection to our decision.
SW: I will gladly take input on mailing list for the next couple of days.
DC: If SW and any other TAG participant say ok to go public, ok by me.
[Support for DC's suggestion from TB and NW.]

Action SW 2002/10/21: Starting from email from SW to TAG, develop a summary of technical discussion and send to www-tag. Include more rationale for original TAG email to HTML WG.

2.3 Other technical issues and actions

  1. namespaceDocument-8
    1. Action TB 2002/09/24: Revise the RDDL document to use RDF rather than XLink. Goal of publication as W3C Note.

      TB: This turns out to be harder than I thought. I am still working on this.

  2. rdfmsQnameUriMapping-6
    1. Completed Action DC 2002/09/24: Write to Schema WG to say that TAG is interested in progress on this issue. Copy Jonathan Borden and Brian McBride.

      DC: The Schema WG is making progress; they will get back to us when they're done. See XML Schema thread on this topic.

  3. uriMediaType-9:

2.4 New issues?

2.5 Postponed

  1. contentPresentation-26
    1. Action CL 2002/09/24: Draft text on the principle of separation of content and presentation for the Arch Doc.
  2. Status of URIEquivalence-15. Relation to Character Model of the Web (chapter 4)? See text from TimBL on URI canonicalization and email from Martin in particular. See more comments from Martin.
    1. CL 2002/08/30: Ask Martin Duerst for suggestions for good practice regarding URI canonicalization issues, such as %7E v. &7e and suggested use of lower case. At 16 Sep meeting, CL reports pending; action to send URI to message to TAG.
    2. IRIs everywhere (including XML namespaces) from Jonathan Marsh. Is this part of this issue or a new issue?
  3. Status of discussions with WSA WG about SOAP/WSDL/GET/Query strings?
