Default Dublin Core Metadata Registry (DC)

The default DSpace Dublin Core Metadata Registry was originally derived from the 15 Dublin Core elements. This registry initializes the default schema, where dc is used to identify the namespace. As this registry is meant to track the Dublin Core standard, it's recommended that the local DSpace administrator not add/remove metadata fields from this namespace; the "local" namespace should be used instead (see below).

Dublin Core Terms Registry (DCTERMS)

The Dublin Core Terms (DCTERMS) registry was introduced in DSpace 4. This registry initializes an optional metadata schema, where dcterms is used to identify the namespace. In DSpace 4, none of these fields are used by any of the system functionality out of the box. The registry and schema were added as a first step to facilitate the future migration of the DSpace specific DC schema, to this schema that complies to current Dublin Core standards.

The main advantage of the DCTERMS schema is that no field name details gets lost during harvesting, as opposed to harvesting of so called "simple" dublin core, where the qualifiers from the above schema are omitted during harvesting.

As this registry is meant to track the Dublin Core Terms standard, it's recommended that the local DSpace administrator not add/remove metadata fields from this namespace; the "local" namespace should be used instead (see below).

Local Metadata Registry (local)

Editing the DC and DCTERMS schemas is recommended against because it may complicate the upgrade path in case a newer version of DSpace needs to make changes or migrations in these standard metadata fields. Therefore, an empty metadata schema called "local" is provided (since DSpace 6), which can be used by the DSpace administrator as a namespace for custom local metadata fields. Such custom fields would be anything that does not fit into DC or DCTERMS. Future DSpace migrations will not touch fields in the "local" namespace.
