I like the suggestion but I think there is only ONE SACM Information model, but there could be more than one data model.  Also, I am not sure what you mean by "Component Identification".  The abstract architecture has components to "provide", "consume", "manage" or "broker"....however, the interfaces who actually allow the components to interact must allow for the interaction to communicate the data model in use, is that what you mean? Or perhaps what you are calling out is a requirement for the information model, whereby the information model "component" that defines the interfaces must have the means to identify each data model uniquely, much to what you have.

So how about:

IM-004: Data Model Identification: The Information model MUST provide a means to uniquely identify each Data Model uniquely. The identifier MUST contain both an identifier of the model and a version indicator for the model. The identifiers SHOULD be decomposable so that a customer can query for any version of a specific model and compare returned values for older or newer than a desired version.

Thanks, Nancy.
