OOI Instrument & Data Relationships
The Ocean Observatories Initiative (OOI) is a 25 year project to monitor the world's major oceans through seven equipment arrays in the Atlantic and Pacific oceans. Petabytes of data will be collected annually. The NSF has asked the OOI Cyberinfrastructure Team, a collaboration of Rutgers Computer Science and Marine and Coastal Sciences, to assign DOIs to datastreams collected from 700+ sensors and instruments so that the data may be cited and archived.
The Rutgers University Libraries are consulted by the OOI Cyberinfrastruture Team, led by the Principal Investigator, Manish Parashar, to develop metadata and DOI assignment for the management, discovery and long-term accessibility of the data.
This poster describes the data model for OOI data, the major decisions that had to be decided, such as when is a data stream changed enough to require a new version and how should data streams be titled, and explain how the application works to assign DOIs to large and complex data sets that are continuously updated.

Project Challenges
Data Versioning
• Inconsistency with source terms• Unclear data definitions• Discrepancies with descriptive metadata• Complex data/instrument relationship• Incomplete data preservation plan
Workflow to Resolve DOIs
Computing platforms, software applications, storage, and high speed network equipment. CyberPoints of Presence (CyberPoPs) include acquisition and distribution points. The Integrated Observatory Network – OOI Net is a redundant computing environment.
