ACTION-88: Check on whether the proposed generic license request/response protocol is in scope of the current html wg charter

http://lists.w3.org/Archives/Public/public-html-media/2015May/0017.html

paulc: Paul spoke to plh about the proposed generic license request/response protocol and plh felt it was NOT in scope for the HTML WG and thus NOT is scope for the TF
... Mark then counterproposed splitting the work as per 0017.html

plh: 2 items to distinguish: a) technical work b) how to fit it in W3C
... on the first item plh encourages the TF to continue the technical work

<plh> http://www.w3.org/2013/09/html-charter.html

<plh> [[

<plh> continue the development of APIs for interacting with in-memory representations of resources that use the HTML language, as well as extensions to those APIs ]

plh: on the second part two items determine what is in scope

<plh> [[

plh: see above quote

<plh> [[

<plh> additions to the HTMLMediaElement element interface, to support use cases such as live events or premium content

<plh> ]]

plh: and there is a second part of the charter which mentions work on extensions to the HTMLMediaElement interface
... see above quote
... I have a hard time squeezing the proposed work into either of the above items
... but if we cannot fit it in currently then we have to figure out how to do the work in W3C

markw: This new work in support for the work of playback of "premium content"
... the connection is tenuous
... If our existing work falls under the two scope items since they fall under the playback of premium content then maybe this work does too

plh: There might be a patent policy complaint here since the "lawyers" might say we are expanding the scope to something new

markw: The charter appears to be much broader than the existing EME and MSE work or the work at the state when the charter was updated to describe the EME and MSE work at that time

plh: I agree the charter is somewhat broader in the statement of work
... If the TF wants to work on this then plh suggests we go ahead

markw: Would it help to keep the work separated in another document?

plh: The good news is that there is discussion going on to create a Media WG and we might very well have a new charter later this year
... maybe at that time we would be more specific
... maybe it will be murky for several months and then will get clarified

<markw__> Sounds good to me

plh: we definitely will not finish even the existing work and will defintiely will need another charter even to cover that existing MSE and EME work

paulc: The F2F meeting suggested that it would be good to have CDMs involved in this new work.
... It might be that this is when we would have the "lawyers" involved and questioning the broadening scope

plh: Yes, and if we need a new charter earlier to handle that then this is a possibility as well.

paulc: paulc: did plh have any thoughts about splitting the work as per 0017.html

plh: The phase 1 proposed by Mark makes sense given what is in EME. What is the difference between Mark's proposed phase 1 and phase 2?

mark2: My proposal was based on speculationg of the rationale for the material being out of scope.
... I will trying to keep the "dragons" into Phase 2

plh: I think it makes sense to work on both parts if we are going to do the work in the TF

paulc: Chair: To summarize then plh recommends that we continue to do the technical work

plh: And we can consider this based on the protocol that is in the EME spec already.

Issue 56 - Examples incorrectly use single quotes for codecs

https://github.com/w3c/encrypted-media/issues/56

Editorial and on the "to be implemented list"

Issue 57 - Clarify behavior for denied user consent

https://github.com/w3c/encrypted-media/issues/57

Related to Issue-51

https://github.com/w3c/encrypted-media/issues/51

markw: My response may have not been on target and I will need to make another issue
... Perhaps a lighter weight approach other than "user consent prompt" would be better

ddorwin: Implementations can do what they want for security matters
... "prompt" only occurs 3 times in the EME document
... and it occurs in a case that we want to remove

markw: For cookies sites usually inform the user that cookies are being used
... it is the "recommendation" that I cannot remember us agreeing to

markw; I will raise another issue to focus on my concerns

<markw__> https://github.com/w3c/encrypted-media/issues/45

Issue-45 - Remove "persistent-release-message" MediaKeySessionType

https://github.com/w3c/encrypted-media/issues/45

Pull request is in https://github.com/w3c/encrypted-media/pull/54

ddorwin: We are looking at implementation impact of pull request 54. Did not have a chance to finish before today's meeting.

jdsmith: I will take a look as well before Jun 2 TF meeting

<ddorwin> "MarkVicksers:… what's being suggested is we put an issue box in the spec, and we (Comcast) will get in touch with WebAppSec WG about the "privileged context" which is more generic than saying HTTPS, etc."
