RE: updated profile registry

Yes, understood – saw that.  I just misremembered that it had been codified there.

 

Perhaps TTML2 doesn’t need the shorthand (tokens or operators) at all.  

 

FYI, we are trying to decouple the registry from both TTM2’s publication schedule and any substantive technical provisions such that it can be approved for publication as a Note by TTWG consensus. This forces an informative suggestion in the registry since the details are not codified elsewhere.

I’ve updated the profile registry based on comments received.  Note that the URL has changed:

FYI, a redirect survives at the “…CodecsRegistry” URL.

 

I addressed the comments (I think) as agreed except for one – after further thought I decided to delete the example rather than try to further explain 14496-30 informatively.

 

I thought the combination syntax was in TTML2, but it is not (should be).  So, I left in an informative suggestion for applications using the registry to enable it.

 

TTML2 uses a more verbose, less compact syntax for expressing conjunctive and disjunctive combination, about which see [1], which employs any() and all() functions. We abbreviated these in the proposed syntax in the registry to accommodate the desire for an abridged representation.

 

IMO, we do not need the abridged syntax in TTML2 itself.

I vaguely recall a 2nd update email on the EBU URN’s but I can’t find it.  If my memory is in fact better than my email filing, then apologies and please send me the changes again.
