Re: EXTERNAL: Re: Proposal for an additional term: mediaType

Laura,

The basic problem at hand that we are trying to solve is exactly the
problem that Jean Godby at OCLC describes in that crosswalk research
paper:
http://www.oclc.org/resources/research/publications/library/2012/2012-04.pdf


that: " But a physical description is problematic because critical
information is coded in many elements in a MARC record, which necessitates
a complex mapping from ONIX and record-level validation of the MARC target
to ensure that the description is internally consistent. "

Physical descriptions
Format descriptions
 ..etc

There is no doubt that we need a MediaType.

The question is to what LEVEL and what PROPERTIES are needed to define a
MediaType that can be easily expanded on for future needs.
We all know that each new Hardware device that debuts each year, sometimes
compounds the problem of Physical descriptions, and Format descriptions.

Never ending change is never ending in this particular problem space.  But
we have to start somewhere.
