EZID: long-term identifiers made easy
take control of the management
and distribution of your research,
share and get credit for it, and
build your reputation through its
collection and documentation
Primary Functions1. Create persistent identifiers2. Manage identifiers over time3. Manage associated metadata over time

• Small required set = citation elements• Optional descriptive set:– extendable lists– can refer to other standards, schemes– domain-neutral– rich ability to describe relationships to other
digital objects• Metadata Search (MDS) is full-text indexed
