IOOS is presently developing and adopting shared vocabularies for terminology such as names of observed properties, units of measure, coordinate reference systems, animal species, etc.
- Ontologies and Controlled Vocabularies: IOOS partners are expected to follow the IOOS Instructions and Guidelines for use of Controlled Vocabularies in IOOS-compliant data services in their implementations. For example, for the US IOOS Biological Data Projects, IOOS has adopted the IOOS Biological Data Ontology.
- Observing Asset Identifiers: In addition, IOOS is defining the IOOS Conventions for Observing Asset Identifiers for sensors, platforms, cruises, models, etc.
IOOS data partners are encouraged to implement, and to help expand, such vocabularies and identifiers, as well as develop cross-walks (i.e., semantic mediation) between IOOS® and existing local or community-of-interest vocabularies and identifiers.
