Implementation Report

<benadida>implementation-report

<danbri> (i wonder if 2008.xtech.org/public/schedule/detail/528 is an implementation report; if implementors include publishers, and not only parser-writers)

Shane: remember, we don't need the implementation report to _start_ CR

Ralph: yes, but we're hoping for a short CR so let's not let it slip

Manu: does every implementation have to pass every test?

Ralph: no, but every feature should be implemented by at least two
... and ideally there will be at least two implementations that do pass everything

Ben: we can include every implementation in the report unless we lose touch with a developer and can't get responses to a test failure
... I do think there should be at least one javascript implementation in the report
... Elias is working on a javascript API for the test harness

Test Cases

Ben: status of tests?

Manu: there are only two pending; let's defer this to next telecon

Manu: I'm not aware of any new tests entering the pipeline

Mark: change made in Shane's CVS repository, will be in the next editors' draft he publishes

ISSUE-113

<benadida> issue 113

-> previous discussion

Manu: the resolution boiled down to "we don't specify this"
... Shane pointed out that the meaning of a fragment may change entirely when put into another document

Ben: it's possible to write a chunk of XHTML+RDFa that will preserve its meaning across documents

Shane: I disagree; in the context of this document we have no formal definition of the behaviour

Ben: in Creative Commons use case we specify a fragment that means what the author _intends_ it to mean when pasted into any document

<danbri> (blogged/syndicated markup is another common scenario)

Ralph: but the subject of the triple changes

Ben: yes, that's why I said "intended to mean"
... in the Use Case document we do talk about fragments, e.g. of widgets
... how should we acknowledge this?

Manu: in the wiki perhaps?

Mark: at the top of the processing rules section there's something that talks about _usually_ starting at the root
... we could make this explicit

Ralph: I disagree that we should specify the interpretation of a parsed fragment

Mark: it's very easy to say "here is the context, begin parsing"
... not saying we need to spell out how to do it
... just that it's possible to answer Micah's point

Ben: I'll try to craft a short non-normative paragraph

<danbri> (NOTE-webarch-extlang#Local articulates something like this requirement)

Mark: the searchmonkey documentation mentions "dataRSS"
... in there you'll find @resource and a statement that "this is RDFa inside dataRSS"
... I hope Ben's paragraph will be sympathetic to this

<msporny> +1 to draft small paragraph

ACTION: Ben draft a non-normative paragraph on RDFa fragments for review [recorded in http://www.w3.org/2008/05/01-rdfa-minutes.html#action13]

Ralph: but issue 113 asks for processing rules that apply when there is no <head> nor <body> and we're _not_ going to do that

Mark: Micah also asks that we "mention the possibility"
... we can mention the possibility without describing normative behaviour

ISSUE-115

-> issue 115; @content

Ben: PFWG's concern is that any markup in the element content is lost when @content is added

<benadida> my response

<benadida> "I like the idea of emphasizing this point, that @content should be used

<benadida> as a "last resort," and we'll discuss it in the group."

Ralph: the point of @content was to override element content when it's necessary to do so
... if the author mis-uses this, then, well ...

Ben: but should we change anything in the spec?

Mark: we have discussed having multiple versions; could have two objects
... we don't have this multiple value approach anywhere else and shouldn't have it here

<ShaneM> "Note that the use of @content prohibits the inclusion of rich markup in your content. It is a tool of last resort. If the inline content of an element is meaningful, then documents should rely upon that rather than duplicating that content using the @content attribute."

Mark: this feature also allows a distinction between XMLLiteral and plain literal

<msporny> +1 for Shane's wording...

Shane: I think we could put guidance such as the above in the document

Mark: I object to "tool of last resort". There are use cases where the thing you want in the human-readable part is different from what you want in the machine-readable part

Ben: the point is that if the value can be rendered on screen, then don't use @content
... Bob Ducharme used to show examples where everything in the HEAD was hidden on-screen and I think we want to discourage this practice

<ShaneM> "Note that the use of @content prohibits the inclusion of rich markup in your content. If the inline content of an element is what you are trying to convey, then documents should rely upon that rather than duplicating that content using the @content attribute."

Ralph: I'd be satisfied with Shane's paragraph with the "tool of last resort" sentence dropped.

<markbirbeck> oops...just remembered that Steven asked me to give his apologies!

<markbirbeck> Very sorry... :)

<benadida> PROPOSE to resolve ISSUE-115 by adding a short non-normative paragraph approximately as follows "Note that the use of @content prohibits the inclusion of rich markup in your content. If the inline content of an element is what you are trying to convey, then documents should rely upon that rather than duplicating that content using the @content attribute."

<Ralph:> +1

<msporny> +1

<markbirbeck> +1

RESOLUTION: ISSUE-115 closed by adding a short non-normative paragraph approximately as follows "Note that the use of @content prohibits the inclusion of rich markup in your content. If the inline content of an element is what you are trying to convey, then documents should rely upon that rather than duplicating that content using the @content attribute."

ACTION: Shane update editors' draft with the resolution to issue 115 [recorded in http://www.w3.org/2008/05/01-rdfa-minutes.html#action14]

ACTION: Ben respond to the commenters on issue 115 [recorded in http://www.w3.org/2008/05/01-rdfa-minutes.html#action15]

ISSUE-104

<benadida> issue 104

PROPOSE propose to copy the datatype definition from WD-curie-20080402/#s_schema

<msporny> +1

RESOLUTION: Copy the CURIE datatype definition from WD-curie-20080402/#s_schema

Shane: the XHTML2 WG had a comment that the correct name is URIorSafeCURIE, not URIorCURIE

Ben: with '[]' it's a SafeCURIE so it's just a wording change

RESOLUTION: change the wording from URIorCURIE to URIorSafeCURIE

<markbirbeck> http://www.w3.org/TR/rdfa-syntax/#sec_6.3.1.

Mark: back on @content ...
... should we use inline markup everywhere whenever we can and minimize use of @content?
... e.g. use something other than META?

Ralph: some of the @content examples have other pedagogical uses and I wouldn't want to do a wholesale replacement
... and about the "small" changes to the processing rules for keeping "useless" nodes?

Mark: they're in the CVS and will be in the next editors' draft

ACTION: Ben send announcement of @instanceof change and diffs to processing rules [recorded in http://www.w3.org/2008/05/01-rdfa-minutes.html#action16]

Ben: I'll take a look at the timeline in the wiki
... the SWD timeline sent on Tuesday should be easy for us to meet

Ralph: regrets for next week

Mark: also regrets for next week

<markbirbeck> There is only one use of @content that should use inline text, and it's in Appendix A.

<ShaneM> Appendix A? really? Appendix A is the DTD implementation isn't it?

<markbirbeck> (I mention that to save people doing a scan.)

<ShaneM> oh.... that appendix A. didn't we remove that?

<ShaneM> we voted to remove that appendix. It is no longer in the source.

<ShaneM> Sorry - fell off the call and can't call back in. conference is restricted.

<Ralph> yeah, in fact Appendix A should use <h1 about="" property="dc:title">Internet Applications</h1>

[adjourned]

<Ralph> (thanks, Mark; I'm happy with your conclusion :)

<ShaneM> I have to go anyway. Ben, do you want me to publish right now, or wait until you have reviewed Mark's mail from last night?

<ShaneM> I have made the changes you requested during the call already.

<benadida> no publish right now.

<benadida> no, COMMA, publish right now :)_
