20:32:46 [IanYVR]
TBray: Should XSLT that transforms RDDL to RDF be included in an appendix of RDDL Note? Should we say anything about standing of that RDF?

DaveO has joined #tagmem
20:37:39 [IanYVR]
TBray: I have not yet created modular DTD.
20:38:05 [IanYVR]
SW: There's an issue about whether we should use XLink or not (per our other discussions about linking).
20:38:41 [IanYVR]
TBray: Original version of RDDL used XLink, but that seemed like a bad use of markup. There are well-known distinguished semantics in RDDL that would be stretching XLink semantics.
20:38:57 [IanYVR]
TBray: Also, this is the smallest possible solution, which I thought would be the best.
20:39:03 [IanYVR]
Action PC 2003/04/07: Prepare finding to answer this issue, pointing to the RDDL Note. See comments from Paul regarding TB theses.

[Comments from PC]
20:40:19 [IanYVR]
TBray: My recollection is that the finding was going to (1) outline how we got here (2) say that it's a good idea to have a namespace doc and (3) RDDL is a candidate.

Theses: http://www.textuality.com/tag/Issue8.html
20:40:59 [Stuart]
Stuart has joined #tagmem
20:41:20 [IanYVR]
PC: There was a sticky point in the original theses about the use of URNs.
20:41:56 [IanYVR]
PC: There is no record of the TAG agreeing with all of the theses.
20:42:02 [IanYVR]
DC: We don't have to agree with all of them.
20:42:21 [IanYVR]
TBray: I think there was broad consensus about most of them except the last couple, #5, and #6.
20:42:45 [IanYVR]
TBray: I propose that we:
20:42:58 [IanYVR]
1) With the blessing of the TAG, revise the Note to provide a more obvious example.
20:43:06 [IanYVR]
2) Dig up XSLT-to-RDF transform and put in appendix.
20:43:29 [IanYVR]
3) PC writes a finding that says namespace docs can be useful and here's a Note that defines a format specific to this application.
20:43:57 [IanYVR]
TBray: I don't think we need to address all of the theses for us to finish this issue.

20:44:10 [Zakim]
DanC_jam, you wanted to test the queue and to play thru some scenairos: RDFS, XHTML, some namespace 'defined' with an XML Schema, some WSDL example
20:44:22 [IanYVR]
DC: I'd like to (1) See three examples of RDDL since it has costs and benefits and (2) I'd like the finding to say that xml schema is another opportunity.
20:44:32 [IanYVR]
s/opportunity/option
20:44:49 [IanYVR]
DC: I'd like examples with RDFS, XHTML, XML Schema, WSDL.
20:45:54 [IanYVR]
TBray: I think that it would be useful to put a RDDL document at the end of an RDFS namespace; for improved understanding of RDF Schema terms.
20:46:48 [IanYVR]
DC: Suppose we have http://www.w3.org/1999/.../rdf-schema@subClassOf as a namespace name.
20:46:57 [IanYVR]
DC: What would my browser show?
20:47:23 [IanYVR]
DC: How do I find RDF triple for subClassOf?
20:47:59 [IanYVR]
TBray: RDDL would point to a directory....
20:48:20 [IanYVR]
[DC draws RDDL document that links to another document with RDF assertions associated with subClassOf]
20:49:09 [IanYVR]
DC: Will the files (.rddl and .rdf) have the same names? I want to use content negotiation.
20:50:10 [IanYVR]
TBray: I think that in some cases you would want to use content negotiation (especially RDF case).
20:50:34 [IanYVR]
[Examine case where file names are different]
20:50:38 [IanYVR]
[I.e., conneg not used]
20:50:53 [IanYVR]
[Chris joins meeting]
20:51:53 [IanYVR]
TBray: So in this example, use nature"= "...rdf-syntax" and purpose = "formalDescription"
20:52:39 [IanYVR]
TBray: You could have another document in .n3, with nature="n3" and purpose="formalDescription"
20:52:47 [IanYVR]
DC: What is content type of .rddl document?
20:53:34 [IanYVR]
TBray: application/rddl+xml or application/xhtml+xml
20:54:03 [IanYVR]
TBray: Most (modern) browsers will handle application/xhtml+xml
20:54:11 [IanYVR]
DC: I get a "save as dialog".
20:54:19 [IanYVR]
TBray: Then you might have to serve as text/html...
20:54:44 [IanYVR]
DC: If we use "text/html" we have to put the HTML WG in the critical path and they'll say no.
20:56:06 [IanYVR]
[See xhtml 1.0 for guidelines on usage of text/html and application/xhtml+xml]
20:56:29 [IanYVR]
DC: I don't have any problem with rddl+xml.
20:57:29 [IanYVR]
DC: I think the RDDL spec needs at least a finding on content type.
20:57:39 [IanYVR]
[agreement]
20:59:04 [IanYVR]
TBray: The RDDL drafts come with a list of canonical natures and purposes
21:00:09 [IanYVR]
TBL: You should be able to get machine readable data without redirection (e.g., through conneg, by embedding RDF in RDDL, or by using RDF in place of RDDL).
21:00:19 [IanYVR]
DO: Another solution - put metadata in the URI...
21:00:40 [Norm]
q+
21:01:44 [IanYVR]
TBray: TBL can put RDF at end of namespace URI if he wants. I would argue with TBL but we have no business forbidding that.
21:02:13 [IanYVR]
NW: What is compelling reason for having RDF right off the bat?
21:02:23 [IanYVR]
TBL: If you can get data in time t, why take it in time t2?
21:02:27 [IanYVR]
DC: It works todya.
21:03:47 [IanYVR]
TBray: TBL's applications are untypical, in my opinion. The most common uses of namespaces is to compare namespace URIs as strings.
21:04:28 [IanYVR]
TBL: It is a core design item of the sem web to be able to get info with only one link, not an indirection.
21:04:41 [IanYVR]
TBray: In my opinion, benefits of indirection are so high you'll end up doing this anyway.
21:06:02 [IanYVR]
PC: Why write a finding if there's no preferred format?
21:06:23 [Norm]
q-
21:06:23 [IanYVR]
TBL: It's good to write a finding that says "It's good to put info at the end of a namespace URI."
21:07:39 [IanYVR]
CL: I don't see the point of a finding that doesn't make any recommendation about a format. Machines have no guarantee of what they'll finding.
21:07:57 [IanYVR]
DC: I think it's good to say "Here are some issues, they are approached different ways with different formats."
21:07:59 [Chris]
Chris has joined #tagmem
21:08:21 [IanYVR]
NW: I have found over last year that I would really like an indirection, and content negotiation is inadequate.
21:09:02 [IanYVR]
NW: It's a chicken and egg problem. APIs won't give indirection if there's no format out their they can know about.
21:09:21 [IanYVR]
NW: "May" use RDDL is good enough for me in a finding.
21:09:40 [IanYVR]
q?
21:11:08 [IanYVR]
Straw poll: (1) Finding says that namespace docs are useful, enumerates some issues, points to RDDL. (2) RDDL Note published.
21:11:54 [IanYVR]
TBray: And in the finding, say that RDF has been useful for RDF applications.
21:12:23 [IanYVR]
Comfortable with that: NW, DC, TBL, CL, TB
21:12:39 [IanYVR]
PC: I want the finding to say that whatever is there should be human readable. We don't seem to be discussing that particular point.
21:12:58 [IanYVR]
q+ TBL, DC
21:13:24 [IanYVR]
TBL: I think that we agree that it's useful to have something human readable. But in a sem web application, the machine readable information is primary.
21:13:25 [DaveO]
q+ DaveO
21:13:46 [IanYVR]
TBL: There are other ways to make the data human readable (e.g., through a style sheet). Don't say "human readable as opposed to machine readable".

q- DC
21:14:20 [IanYVR]

[Grumbling about level of human-readability of http://www.w3.org/2000/10/swap/pim/email]

21:17:18 [IanYVR]
DO: I'd like the finding to say "SHOULD be human-readable" and MAY for RDDL.
21:18:13 [Stuart]
q?
21:18:38 [IanYVR]
DC: My point is that an RDF document can be human-readable when displayed with style sheets.
21:19:07 [IanYVR]

CL: What's the test for human-readable?

q+ to suggest a finding part saying taht machine-readable files can be made (more) human readable using various techniques.
21:19:48 [IanYVR]
PC: In many cases, a title at the top, "This doc defines the meanign of the namespace FOO. How it's used...what additional resources are available...purpose of namespace"
21:20:07 [IanYVR]
PC: Also include why someone might want to use the additional resources.

21:29:49 [DaveO]
Is this "Namespace document Best Practices?"
21:30:02 [IanYVR]
PC: If you have multiple schemas for the same thing, RDDL gives you advantages.
21:30:38 [IanYVR]
PC: If you only have one format and it's absolutely a characteristic of the application that performance is important, ok to use single format, but cost to losing human-readability and indirection.

21:38:41 [IanYVR]
[TB to summarize points for PC's finding]
21:38:50 [TBray]
Finding should say:
21:38:56 [TBray]
1. human-readability good
21:39:07 [TBray]
2. indirection good
21:39:20 [IanYVR]
3. Namespace doc good
21:39:44 [IanYVR]
PC: Usage scenario v. design scenario.
21:39:59 [TBray]
4. some risk in betting on some format being the One & Only Format
21:40:04 [IanYVR]
PC: There are advantages of indirectoin to have multiple different resources for human wnating to use the namespace.
21:40:42 [TimBL-YVR]
Point out the ability of RDDL to carry indirection.
21:40:59 [TimBL-YVR]
Point out the ability of RDF to contain arbitrary eg dublin core metadata.
21:41:29 [IanYVR]
TBL: Useful to have an example using RDDL and an example using RDF?
21:42:07 [IanYVR]
PC: I think the finding will give some examples of namespace docs.
21:42:30 [IanYVR]
TBray: For the Note, I've agreed to put some examples in, to include xslt script in appendix.
21:42:37 [IanYVR]
TBray: And say a few words on content type.
21:42:54 [IanYVR]
NW: You need to inline natures and purposes (i.e., put the list in the spec)
21:43:15 [IanYVR]
DC: Put some examples showing their usage.
21:43:31 [IanYVR]
NW: One of the natures should be "RDDL Document" (forward versioning)
21:43:48 [IanYVR]
q?
21:43:56 [IanYVR]
q- TBray
21:45:02 [IanYVR]
PC: I think that reasons for publishing Note have slipped by.
21:45:12 [IanYVR]
PC: There might be other technical issues, we might want to register content type.
21:45:28 [IanYVR]
TBray: I think if we publish Note we've done our job.
21:45:51 [IanYVR]
PC: We should also send email to the AC explaining our position.
21:46:24 [TimBL-YVR]
q?
21:46:26 [IanYVR]
IJ: I heard from AC meeting "Publish as Note first, then we'll figure out what to do."

TBray: I think happy medium between minimal approach (DC) and SW's current finding.
22:17:58 [IanYVR]
[Roy joins meeting]
22:18:42 [IanYVR]
1) When you are processing a URI, there are normative specs (starting with [URI], then scheme specs); it's fine to peek inside URIs and interpret per normative specs.
22:19:01 [IanYVR]
2) Beyond that it's inappropriate to make other assumptions by peeking in URI UNLESS you have private agreements.

q+ to ask for a summary of any substantial points made on the thread not compatible with the finding as is.
22:20:53 [IanYVR]
DO: I think that we need to describe when it's ok to peek inside a URI. And when it's ok to write a spec that says it's ok to peek inside a URI.
22:21:07 [IanYVR]
DO: I had an action item to talk to WSDL folks about why they want to peek inside their URIs.
22:21:30 [IanYVR]
DO: They have created a number of symbol spaces. Names are not unique across symbol spaces. They want to use the symbol space to differentiate items.
22:21:36 [IanYVR]
DO: (Issue 37)
22:21:55 [IanYVR]
DO: They want to have metadata in a well-defined format so that software can have predictability for how to process URIs in WSDL docs.
22:22:07 [IanYVR]
DO: So the WSDL spec would be a normative spec for how to interpret the URIs in WSDL docs.
22:22:24 [TimBL-YVR]
q+ to aska determining question of DO as to whther a non-WSDL-sware agent could be able to determine what is denote dby one of these URIs in the WSDL URIs.
22:22:29 [IanYVR]

23:04:11 [TimBL-YVR]
The server writer and the server administrator own teh URI space on a server. As WSDL spec writer, you can't put constraints on that space, or there will be horrible clashes. The URIs on web servers are generated from exposed foreign systems, databases, etc.

23:39:07 [IanYVR]
DC, TBL: I don't agree with 6.
23:39:15 [Chris]
I can extract a type (dateTime) from that URI or rather, I can use that URI to identify dateTime type
23:39:16 [IanYVR]
TBL: Req 6 is architecturally harmful.

DC: Issue 28 related - do frag ids refer to syntactic element or can they refer to abstractions?
23:42:32 [IanYVR]

23:49:56 [IanYVR]

23:50:37 [IanYVR]
RF: Lots of human error possible in generation in individual names.
23:50:45 [IanYVR]
[option 3]
23:50:57 [IanYVR]
Require Unique NCNames.
23:51:05 [IanYVR]
DO: You combine the symbol spaces into one.
23:51:33 [IanYVR]
DO: You combine the symbol spaces into a single space, within a particular WSDL document.
23:52:08 [IanYVR]
TBray: This is identical to choosing an id.
23:52:17 [IanYVR]
TBray: 3 is a flavor of 2
23:52:40 [IanYVR]
Option 4
23:52:43 [IanYVR]
Use XPointer
23:52:54 [DanC_jam]
(perhaps ask who prefers this option when asking who could live with it)
23:53:21 [IanYVR]

q+ to ask about qnames
00:04:40 [IanYVR]
TBray: RFC2396bis still says that the format and resolution of frag ids depends on media type.
00:05:15 [IanYVR]
TBray: Option 8 is at odds with this.
00:05:37 [IanYVR]
DC: If the guy doesn't fetch the resource, it's not that RFC2396bis has been violated, but person who has dereferenced is taking a risk.
00:07:32 [IanYVR]
DO: If one follows option 8, it will lead people to put WSDL docs at end of their namespace URIs, and if they don't they incur risk that frag ids will not make sense.

yes, figures please
00:19:21 [DanC_jam]
yes, well, Ian, I think it's useful for the TAG to let those authors know that they're fighting the medium. There's a time and a place for that, but we can and should be clear that it's not usually good.
