## Goals

"DASH/CDL/IA/Dat importer"
    => start with local dat clone w/ discovery key; releases that have DOI
        => but may need to create release if datacite
    => enumerate and hash all the files under 'data/'
    => process metadata from cdl_dash_metadata.json
    => construct fileset entity
    => set extra['ark_id']
    => set extra['related_works'] = [] (?)
        => or group under the work?
    => add: rel=dweb url=dat://.../files/
    => add CDL... repo-bundle?
        https://merritt.cdlib.org/u/ark%3A%2Fb5068%2Fd1rp49/2
    => add CDL... repo-dir?
        https://merritt.cdlib.org/d/ark%3A%2Fb5068%2Fd1rp49/2/021611_H929.txt

Unfortunately, looks like these ARKs don't result (get a tombstone, "Object in
restricted Merritt collection"): http://n2t.net/ark:/13030/m53r5pzm
