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
