JSE: The technique that Farrukh refers to can also be thought of as applying a
"template": for an artifact of a particular "type", instantiate a record of
pre-defined structure as specified by the template (or schema). This might
include both manual and automatically-generated data elements, the later
(perhaps) derived from some transformation of the submitted artifact.

Clearly, the distinction between content and metadata is an application-level
concern; this must be up to the interpreting application. A given data element
might be useful as "metadata" to one class of interpreter, but as "content" to
another...

This also ties back to the observations about application profiles made
earlier in the week...
