Metadata "about" resources: basic and curation metadata (id, name, title,
contact, location, etc)

Metadata "contained by" resources: metadata contained in the data archive,
data processor, data storage, etc.  This is the dreaded "metadataFormat".
If the resource were a star catalogue, the "contained by" metadata would
be ramax, coordinates, wavelength, magnitude, etc.  I would really like a
better way to express this concept.
