I re-read the current draft of the Ontology document, and I think that  
it shapes up nicely, good job! I still have a set of comments though,  
sorry to send them late to the mailing list, but it looked like the  
ontology document was updated on an hourly basis, so I was waiting for  
a stable version to be accessible :)
Below, my list of comments.


1/"This vocabulary describes a mapping between different schemas  
containing this property."
-> this is not what we do, but we do what is described later in the  
same section: define a set of mappings between the values/properties  
of a set of schemas and the porperties of our own name space.

2/ "More importantly, the Dublin Core properties have been created  
with a set of restrictions, although loose, and we might want to apply  
other restrictions to our properties."
-> to change to "we want", not might want

3/ "A list of properties by a cross validation between the member's  
opinion and the popularity of the properties across the vocabularies  
has been selected in order to get some level of objectiveness."
-> A list of properties has been selected by a cross validation..., in  
order to...

4/ I do not understand the meaning of the namespaces in the Datatype  
column of the media ontology (ma core properties) definition table

5/ ma:identifier for example has something that looks like a pair as  
Datatype, but the textual description does not mention the fact that  
the value is a pair, unlike some other properties which have pairs as  
values: is the value a pair or not? If it is one, this should be  
mentioned in the description.

6/ "4.2.1 Rationale regarding the mapping table"
the namespace ma is introduced here only, although it is used in the  
previous table. Generally, this paragraph does not integrate well with  
the introduction to the previous table and should be rewritten to fit  
the document better, and focus on the transition: the above listed  
properties are the ones to which the selected set of metadata schemas  
has been mapped. The rationale for selecting formats has already been  
described before.
