DOIs will be used in addition to Handles. This implementation does not replace Handles with DOIs in DSpace. That means that DSpace will continue to generate Handles for every item, every collection and every community, and will use those Handles as part of the URL of items, collections and communities.

Currently, the EZIDIndentifierProvider EZIDIdentifierProvider has a known issue where it stores its DOIs in the dc.identifier field, instead of using the dc.identifier.uri field (which is the one used by DataCite DOIs and Handles).  See DS-2199 for more details. This will be corrected in a future version of DSpace.

DSpace currently generates DOIs for items only. There is no support to generate DOIs for Communities and collections Collections yet.
