<trackbot> ACTION-123 Come up with ABNF for header syntax closed

Raphael: Frank Denoual has commented on Silvia's work and Silvia has addressed the comments
... I'm all for giving an action to Yves for reviewing the ABNF

<erik> +1

<scribe>ACTION: yves to review the ABNF syntax of the HTTP headers introduced by the Media Fragment URI spec [recorded in http://www.w3.org/2010/05/26-mediafrag-minutes.html#action03]

<trackbot> Created ACTION-166 - Review the ABNF syntax of the HTTP headers introduced by the Media Fragment URI spec [on Yves Lafon - due 2010-06-02].

Raphael: rendering of fragment in UA ... how far should we go

Davy: we should discuss possibilities, but not provide recommendations

3. Test Cases

ACTION-164?

<trackbot> ACTION-164 -- Erik Mannens to report to the group whether such an approach from RDFa test suite can be used for automatically testing the media fragment specification -- due 2010-05-26 -- OPEN

<trackbot> ACTION-164 Report to the group whether such an approach from RDFa test suite can be used for automatically testing the media fragment specification closed

Michael: ok with the extension, but my problem is that we do not rely only on the HTTP status code
... there is also the need for a user assessment that the visual rendering is correct

Raphael: really? if we do not recommend the rendering of a fragment, then no need ... for the automatic test suite
... and there are 2 kind of evaluations, server side and UA side
... for me there is test suite for the UA (correct parsing of the media fragment URI syntax + correct rendering of the fragment?) and the test suite for the server (the automatic test suite from Davy we are talking about)

Davy: we have done our own implementation, JSON files, no DB, but we would like to link it to corrib now

Michael: is there some pointers I can have a look to to better understand what you have done

Raphael: can we say that mftc:expectedHTTPStatusCode
... returns a 2xx ?

<mhausenblas> http://tools.ietf.org/html/draft-ietf-httpbis-p2-semantics-08#section-8.2.1

Raphael: for a 206 or a 200

<mhausenblas> http://tools.ietf.org/html/rfc2616#section-10.2.1

Raphael: I like this ontology:http://www.w3.org/2008/http-statusCodes
... My other concern is do we want a litteral for the property mftc:expectedVisualResults ?
... or do we want controlled values ?

<mhausenblas> http://www.w3.org/TR/HTTP-in-RDF10/

Michael: do we really need this property if we test the server?

Davy: no automatic evaluation for this one, not trivial
... we actually test more than the HTTP headers, for example that the bytes sent in the body of the response correspond to the original bytes in the media

Michael: I would suggest to remove this property if we don't see how it will be used

Davy: I'm thinking of using corrib for testing also the UA side
... so I might need it later on
... then we need to think now about the test framework for the UA side!
... because we will NOT edit again and again the test suite

Michael: I agree with you

Raphael: how we should proceed then ?

Erik: should we have test movies ? How many ?

Raphael: we can use the one Silvia is using (the cartoon, need to find the title) used by Mozilla demos
... we don't need many, perhaps 5 in different formats, would be good

<silvia> Elephant Dreams

Raphael: Silvia, if you're reading, could we give you an ACTION to find 4-5 movies, licence free, we could use in our test cases ?
... Elephant Dreams is one of them
... what else ?

<silvia> very hard indeed

<silvia> I go to creative commons and download from there

<mhausenblas> Michael: Server-Test Suite would consist of: corrib-output (RDF): manifest, media files, driver (takes manifest and applies to each set of media files and generates EARL)

<scribe>ACTION: Erik to find licence free movies for the automatic test suite ... starting with Elephant Dreams and the creative commons [recorded in http://www.w3.org/2010/05/26-mediafrag-minutes.html#action04]

<trackbot> Created ACTION-167 - Find licence free movies for the automatic test suite ... starting with Elephant Dreams and the creative commons [on Erik Mannens - due 2010-06-02].

<silvia> http://creativecommons.org/videos

<scribe>ACTION: Davy to investigate how the automatic test suite could also be done for evaluating the UA behavior [recorded in http://www.w3.org/2010/05/26-mediafrag-minutes.html#action05]

<trackbot> Created ACTION-168 - Investigate how the automatic test suite could also be done for evaluating the UA behavior [on Davy Van Deursen - due 2010-06-02].

<silvia> just get videos from there

Raphael: we are waiting for the output of this action before asking Michael to extend corrib

4. AOB ?
