draft for "Canonical Processes" Use Case and updates to the UC and Req document

Hi everyone!

Following my Action Item, here is a draft of a Use case that would  
correspond to the "canonical processes" applied to a media document,  
as discussed in the last teleconference (). All comments are welcome!

I also updated the current Use Case and Requirement document according  
to the list's comments and reactions.

Best regards,

Title: Canonical Processes Use Case

Summary: The life cycle of a media document undergoes different  
processes, which have all different canonical metadata properties and  
schemas. It is not trivial to pass on valuable metadata, generated  
during one process, to the next process. The Media Ontology could  
enhance the transmission of metadata in this chain that has been  
identified as the "Canonical Processes" [1]

Related Requirements:
Requirement r01: Providing methods for getting structured or  
unstructured metadata out of media objects in different formats
Requirement r05: Providing the ontology as a simple set of properties

Description / Example:
As described in [1]:
"Creating compelling multimedia presentations is a complex
task. It involves the capture of media assets, then editing
and authoring these into one or more final presentations.
Tools tend to concentrate on a single aspect to reduce the
complexity of the interface. While these tools are tailored to
support a specific task, very often there is no consideration
for input requirements for the next tool down the line. Each
tool has the potential for adding semantic annotations to the
media asset, describing relevant aspects of the asset and why
it is being used for a particular purpose. These annotations
need to be included in the information handed on to the
next tool."
The Media Ontology would help the information transfer or access  
between these different processes.
