Out of scope: External identifiers not recognized by the system or stored in explicit metadata properties.
REQUIRED FOR ALL REPOSITORY OBJECTS
UUIDs (id): Internal identifiers created by the DDR application. These will change with system migrations. UUIDs are generally not visible to end users, except that they are used to construct URLs for all DDR objects that aren't assigned a Local ID (see below).
...
Handles: Created automatically for all objects by the DSpace system (dukespace.lib.duke.edu), handles function as the permanent URLs to those objects, and are included in the public interface as citation links.
Example: http://hdl.handle.net/10161/14575
REQUIRED IF APPLICABLE OR OPTIONAL
DOIs (doi): DOIs are unique identifiers widely recognized as the standard way to cite digital academic materials. DOIs will be assigned only to objects ingested and preserved in the RDR per our agreement with CrossRef, our DOI provider. DOIs are currently minted through CrossRef by the ingester via a feature in the RDR UI.. DOIs are reserved for scholarly works that expect to be cited, are issued only to objects for which there is a commitment to persistent access, and impose a minimum metadata requirement to ensure the integrity of the DOI system. Currently, the Research Data Repository is the only platform using DOIs, and DOIs are minted at the collection level for every collection at time of ingest unless the data collection has already been assigned a DOI from an external service or repository.
