3. SPECIFICATION


RE: ACTION-134: Erik to mark up the spec with normative and informative
classes

raphael: thinks it's too early for such markup
... should be last thing we do
... still subject to lots of discussions
... could start marking up on the parts that are major

silvia:
http://lists.w3.org/Archives/Public/public-media-fragment/2010Feb/0007.html
... has a list of things that could be marked up already
... not possible for everything of course

raphael: would rather want to get implementations

mhausenblas: agree, statements are too early
... could change still

raphael: support the path that silvia mentions

<mhausenblas> Michael: we should flag stable vs. unstable sections rather
than normative vs. informative

raphael: just marking some sections as "ready for implementation"

<raphael> Section:
http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#npt-time

<raphael> is stable providing the correction of the npt bug

<mhausenblas> Michael: this is IMO, what implementers are primarily
interested in

<raphael>
http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#processin
g-protocol-UA-mapped

raphael: correct npt scheme
... no action yet
... should include diagrams that Erik sent

<mhausenblas> ACTION-126?

<trackbot> ACTION-126 -- Yves Lafon to follow up on error in ABFN for npt --
due 2009-12-23 -- OPEN

<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/126

silvia: Yves said he would do the changes by next week

raphael: make sure Yves completes by next week

erik: first job on diagrams
... only includes main headers, not all headers

michael: should include all headers

silvia: haven't looked at the diagrams indepth

michael: a decision for who marks it up to include what is most important

erik: will look at it again

silvia: we could also rely on implementers to give us feedback

raphael: suggest to give action to somebody to integrate diagrams into
document

5. TEST CASES: (Michael)


michael hasn't had the time to spend on test cases

raphael: need another volunteer to keep this going

michael: I will not be able to drive this
... need a volunteer to take over

erik: we can do it but not before april

<raphael> Silvia: I'm not sure we need a responsible person, no stress on
someone in particular

<raphael> ... it could be a collective effort

<raphael> Michael: I think you're right, but getting a person setting up the
policy for external reviews is important

<raphael> ... for that, it is good to have a face

silvia: could be part of the natural sequence of (1) defining use case, (2)
defining solution, (3) defining error and test cases

raphael: during f2f we could collectively discuss test cases that are well
enough defined

<mhausenblas> Michael: the 'collective approach' actually made me
propose/implement http://ld2sd.deri.org/corrib/

raphael: we should do all of the above :)
... define test cases during f2f
... have a person responsible from April to follow up

michael: main motivation is to get the implementation report in just one
click
... this is what corrib has been set up for

<tmichel> A Method for Writing Testable Conformance Requirements

michael: should be decided at f2f

<tmichel>  <http://www.w3.org/TR/2010/NOTE-test-methodology-20100128/>
http://www.w3.org/TR/2010/NOTE-test-methodology-20100128/

erik: I like the one-click approach to report

<tmichel> document presents a method for writing, marking-up, and analyzing
conformance requirements in technical specifications.

silvia: agree to having somebody responsible to look after corrib for
checking implementation conformance

micheal: implementation report is part of our charter

+1

erik: exit criteria we will write in CR document

raphael: should we look at test cases now?

michael: can show what I've done so far
... classification of test cases
... move into wiki

<mhausenblas> ACTION-115?

<trackbot> ACTION-115 -- Michael Hausenblas to come up with categorization
of test cases wrt empty, undefined, etc -- due 2009-09-30 -- CLOSED

<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/115

michael: uploaded an rdf document that defined all the cases

<mhausenblas> http://www.w3.org/2008/WebVideo/Fragments/TC/mftc

silvia: is that out of corrib?

erik: can we get a more readable version?

<mhausenblas> ACTION: mhausenb to create a more readable version of the TC
classification at http://www.w3.org/2008/WebVideo/Fragments/TC/mftc
[recorded in http://www.w3.org/2010/02/10-mediafrag-minutes.html#action03]

<trackbot> Created ACTION-140 - Create a more readable version of the TC
classification at http://www.w3.org/2008/WebVideo/Fragments/TC/mftc [on
Michael Hausenblas - due 2010-02-17].

silvia: for me it's not about readability, but about how to edit

michael: you have access to the file - it's in cvs
... will create a readable html page out of it

silvia: question whether we should address the test case for time dimension

michael: what differences did you have

silvia: only one major difference to before

michael: would need to work through the list
... prefer to delay to next week

erik: any other topic?
