RE: Proposal to modify Classifications in ebRIM

["Breininger, Kathryn R" <Kathryn.Breininger@PSS.Boeing.com>]

Len,
I have reviewed the proposal you submitted, and do have a few comments.

I agree with your scenarios and requirements for Use Cases 1, 3, 4, and 5.  I can see a real need (and we have had requests already for our registry) to register a classification scheme in a registry.  This makes sense, and provides a place where a user can find classification schemes that they may want to use as well. 

I have serious concerns about Use Case 2 and the associated requirements.  This use case assumes that all users will want to retrieve the entire classification scheme as an XML document.  Requirement 2a makes sense - it should be possible to register the entire classification scheme with its own metadata.  The first part of requirement 2b makes sense as well - the RIM should treat a classification scheme as a repository item with its own registry entry, and the registry entry should provide a web link to the registered classification scheme (I would add, "if available").  However, invocation of that URL should not necessarily return the entire classification scheme as an XML document.  Not all users will want to retrieve an XML document if all they want to do is look at a specific classification scheme.  In addition, there are numerous classification schemes that are public, and are used and available for use by anyone in any company (Dewey Decimal Classification comes to mind!
, as well as the Universal Decimal Classification, SIC, MESH, RCC, LC, etc. (I gave up providing the full names, but can translate all the acronyms if you want!)).  Any of these classification schemes may be used by anyone to classify their registered items, and requiring that these be translated into XML documents does not seem reasonable, nor do I see a use case to support this.  It may be something to consider as an option, especially if someone is creating a small, home grown classification scheme.  However, requiring conversion of all classification schemes into XML documents does not add value that I can see, nor do I see a need for it.
