Hi Christian,  

Thanks for posting the list of sorts of capabilities you were thinking about.

You're right that some of these might be considered out of scope for the DDWG itself, but I think most are actually potentially in-scope for parts of the ontology that might be used by other folks.

Network capabilities (bearer, bandwidth etc...) are of interest to the OMA group that is also involved in work associated with the ontology. In fact it's one of their major use cases, so I'd expect to see those characteristics appear in the ontology. It remains to be seen whether DDWG wants these too.

Adaptation capabilities, transcoding ability etc. is an area we've not looked at in any of the groups involved with the ontology as far as I can recall. That's probably just because, historically, browsers and devices haven't been able to do this. That is changing and I can see this being an area of potential interest going forward. 

Thanks for bringing these up. 

Best wishes
Rhys

Thanks Jo, Rhys for clarification.

[Christian Timmerer (ITEC)] ... network capabilities (e.g., avail. bw), de-/encoding (e.g., JPEG, MPEG-4, etc.) capabilities, and adaptation capabilities in general (e.g., transcoding from MPEG-2 to MPEG.4, grayscaling, temporal/spatial scaling).

This might be useful for providing adaptation services within the delivery path enabling device independence at the end user device. However, I agree with you that this might be out of scope of this WG.

Thanks anyway...
Best regards,
 -Christian
