Fedora Enhanced Content Models

Warning This page is no longer updated. The project is moved to http://ecm.sourceforge.net

Fedora is at the core of the new DOMS (Digital Object Management System) being developed at the State and University Library. For this system,
we needed more powerful content models. More specifically, we needed content models the describe the xml schema for datastreams, cardinality
restrictions on relations and allowed types for the target of relations. In addition, we needed to retain compability with the original fedora
system.

...

• Active: The object is published and available. The object has been validated against the content models that describes it.
• Inactive: The object is not publicly available. It is not guaranteed to be valid in regards to the content models that describes it.
• Deleted: The object is deleted, and should not be available to anyone. It is in no way guaranteed to be valid. It is still in the repository, and special administration tools should be able to resurrect it.
