Abstract
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.

OOI Instrument & Data Relationships
OOI Subsite Sample Record in RUcore
Inconsistency with source terms
Unclear data definitions
Discrepancies with descriptive metadata
Complex data/instrument relationship
Incomplete data preservation plan
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.
