3. Items
[A] Action items:

[B] If we have a quorum, discuss the set of changes to the (abstract) Ontology, summarized here by Jean-Pierre:

- It is proposed to add track as a sub-class of fragment to help aligning with MFWG
- It is proposed to add videoTrack and audioTrack to which currently existing specialised properties like frameRate or sampleRate will be more specifically linked as well as a better use of the compression property
- It is proposed to add captioningTrack to better align with MFWG and also to address subtitling more properly

- It is proposed to change createDate (or creationDate) as "date" and list createDate (or creationDate) at the same level as releaseDate, etc.  This allows better hierarchical representation of dates in the RDF ontology as, for example, releaseDate cannot be considered as a subclass of createDate?

- RatingValue should be float but it should now have been corrected in the API following today review of actions.

- language and compression should allow string but also anyURI values, which would allow using SKOS concepts from classification schemes

[C] Follow up on Implementation of LC comments

1- Media Ontology spec

-- LC Comment -2393 : NOT reviewed
-- LC Comment -2405:  JP Evain:
-          Note to implementers, content authors - not really explicit, maybe these roles should be mentioned saying things like "it is expected that implementers will do."  ". to the benefit of content providers", etc.

-          There is no section 1.1 on the purpose of the specification (yet)

Section 4.1 core property definitions -> now section 5.1
-          The ma: prefix still appears in the table but since the comment was made Pierre Antoine, while working on the mapping table suggested that the prefix should only be used with the ma-ont namespace in the RDF -> reconsider position?

Section 4.2.2 - no change as explained in previous response - tables in line -> now 5.2.2

Joakim: "our specification" is replaced by "this specification" (OK), But "our Ontology" (two occurrences in section 1)

Other comments from JP review

The abstract and introduction should mention the definition of the RDF ontology and the mapping table that will come with it.

[D] reminder : Metadata examples needed!

During the F2F in Lyon, we decided to verify our mapping ontology by
having metadata in each format
