As Elizabeth has suggested, METS seems to be a much better fit for
what you are trying to achieve. METS is an extremely generic xml
schema coming out of the library world, but it's much less geared
towards a specific type of community practice or type of content than
the EAD. A METS document encodes one single Digital Object, which may
comprise many multimedia files (image, audio, video). The object
typically contains a hierarchical structure (such as the chapter /
page structure of a book) pointing toward the surrogates. METS
objects may also carry extensive descriptive metadata about the
original (often physical) object described, used for discovery; as
well as extensive administrative metadata such as technical metadata
about the multimedia files, or rights metadata etc. It looks like
METS will find wide adoption as a file exchange format, as a means to
manage archival digital files and as a way to present digital
Museums, libraries and archives probably will wind up using METS as
an extension of the EAD. While the EAD will be used to describe and
structure collections, METS may be used to deliver extremely granular
digital surrogates of the objects in the collections. The Online
Archive of California (OAC) has adopted a strategy to use METS that
way, and we've just started developing a best practise guide for METS
as implemented in the OAC.
