A Content Information Type Specification is a mechanism used to extend the scope of the CSIP?

[jmaferreira]

I disagree with this sentence:

A Content Information Type Specification is a mechanism used to extend the scope of the CSIP by defining additional requirements for specific Content Information Types. The OAIS Reference Model defines Content Information as “A set of information that is the original target of preservation, or that includes part or all of that information. It is an Information Object composed of its Content Data Object and its Representation Information”.

A CITS does not extend the scope of the CSIP, it narrows it by specifying what particular formats and information should be place where. The CITS is always a subset of the CSIP, therefore it does not extend the scope. It narrows the scope.

Do you agree?

Thats is seen both ways depending on who you ask, thats the tricky part. I'll see if I can make it clearer.
