Agenda+ Santa Clara F2F October (TPAC)


Our TPAC2014 wiki page is at [1]. Draft Agenda and attendees section now added.

Any more agenda items?

Does anyone want to use the 1100-1500 period for meeting time or for ad hoc meetings? See TPAC2014 ad hoc meeting wiki page at [2].

We have been asked to tell other groups if we can free up our room in the ad hoc meeting period.

Lunch can be scheduled any time between 12:00-14:00. 

Morning breaks can be scheduled any time between 10:00-11:00.

Afternoon breaks can be scheduled any time between 15:00-16:00.


Attendees who have not yet registered may do so on the day (USD150 per day), however some (other) groups are now at capacity.



Agenda+ IMSC CR Exit criteria


What questions do we need to answer to derive the appropriate exit criteria for IMSC CR? 

Note that we have a session for this in the F2F agenda, so this agendum is for understanding the problem space.


Considerations I have gathered from other CR exit criteria:

*	Do we want to require a minimum number of interoperable implementations for each feature?
*	Do we want to test only the features with feature or extension designations? What about conformance requirements that do not have designations?
*	How do we define interoperability?
*	What levels of maturity, completion and availability do we require for each implementation to consider it?
*	What types of implementation do we want to see? Any? At least n document validators and at least m presentation processors?
*	Do we require any particular implementation approach? 
*	Does it matter if implementations can process standalone documents, or do they need to process documents and associated video objects simultaneously?
*	What is the minimum duration of the CR period?
*	What commitment does the TTWG want to give to responding to issues raised during the CR period?


Agenda+ WebVTT publication


Carried over from last week: can we resolve to publish [3] as an FPWD?


We decided to use  <http://www.w3.org/TR/webvtt1/> http://www.w3.org/TR/webvtt1/ for the short name.
