Hi Davy,

Thank for summarsing the semantics, that will help me answering the question... (I hope :-)

[[ Therefore, we should first look at the definition of a media resource [1] and I believe that a media fragment
falls under that definition (if not, please clarify why not):
" A media resource is any physical or logical Resource that can be identified using a Uniform Resource Identifier (URI), as defined
by [RFC 3986]) , which has or is related to one or more media content types."  More specifically, a media fragment is a physical
resource, with a media content type (i.e., the same as its parent resource) and can be identified using a URI (i.e., a Media
Fragments URI).]]
This is effectively the key question and I would inviote the whole MAWG to consider this question.

My first intention would have been to have media fragment as a subclass of media resource composed of audio and video tracks. If we all adopt and recognise more specifically that a fragment is a media resource which is iodentified by a MFURI I am happy with this but the group needs to confirm what the mediaFragment is. Then we could name (namedFragment, itself a subclass of fragment) and keyword a fragment and give him a URI. That would be 'clean'. 

Then  if the question arises of whether a media fragment is a subclass of media resource, I would answer that any media resource is an atomic media fragment.

In other words, I personally can agree with what you suggest but would like to hear from the group.

Tobias and team, what do you think?
