Eric: I'm not a Fedora developer, so this is more descriptive than prescriptive: The DC datastream has more format restrictions than are immediately obvious. I believe this is because the Fedora developers intend for that datastream to function as a tool for administrative identification of digital objects in the repository, rather than discovery per se (that's a personal assessment, so caveat emptor).
You can get a listing of the DC fields that get processed by reviewing the source for fedora/server/utilities.DCFields.java: dc:creator dc:subject dc:description dc:publisher dc:contributor dc:date dc:type dc:format dc:identifier dc:source dc:language dc:relation dc:coverage dc:rights These properties are indexed in the triplestore, which is probably why your attributes are dropped. The DefaultDOManager class also sets the content of the DC datastream as the serialization of the post-process DC data (not the original). If you want to change these behaviors, you could use a local DOManager implementation. I'm sure the developers would also welcome new feature requests related to specific changes in this process, if you have a JIRA account. regards, Benjamin Armintor On Tue, Jun 2, 2009 at 9:41 AM, Eric Coopey <[email protected]> wrote: > Fedora is stripping out namespaces and the associated attributes in the > Dublin core file.
