I agree that adding techMD to the METS is architecturally the right thing, but there is already a better (or at least, adequate..) technical metadata standard format in PREMIS. There is already a PREMIS crosswalk for the import/export METS packager which you can cannibalize, see org.dspace.content.crosswalk.PREMISCrosswalk
You could put the format name in the element: objectCharacteristics/format/formatDesignation/formatName The crosswalk puts the MIME type there right now, but it would make more sense to use it for the name. (At the time I wrote the crosswalk, I didn't feel it was correct to dignify the chaos that is MIME types by calling it a "registry" of format identifiers, although we currently use it as such.) Then you can use PREMIS for other bits of technical metadata of use to Manakin, instead of perverting DIM. DIM was never supposed to escape beyond the internal use in XSLT-driven packager crosswalks! There's more about PREMIS here: http://www.loc.gov/standards/premis/ -- Larry > The METS <file> element lets you have an "admid" attribute that points > to administrative metadata about the file elsewhere in the METS > document.
