Abstract
|
The ontology structures observatories across three main hierarchical levels:
Regional Facilities – large-scale marine areas under long-term observation,
Sites – specific geographic locations within a Regional Facility where observations take place,
Platforms – physical structures (e.g., cabled observatories, moorings, landers) deployed at a site to carry scientific instruments.
Two additional levels are planned for future development:
Measured Parameters – describing the observed phenomena (e.g., temperature, pressure, biogeochemical indicators),
Datasets and PIDs – linking observations and parameters to their corresponding published datasets (with persistent identifiers such as DOI).

Accrual method
|
Manual and community-driven curation, based on expert contributions and the progressive formalisation of domain knowledge. Updates are proposed through real-world use cases and validated by the ontology editors.

Accrual policy
|
New content is added based on expert consensus and validation by the core ontology team (e.g., the EMSO Data Management Service Group). Updates follow a controlled process to ensure semantic consistency, alignment with external references, and sustainable reuse.

Developed in the context of the EMSO-ERIC, the OSO ontology supports the FAIR principles (Findable, Accessible, Interoperable, Reusable) by enabling semantic integration of marine observation data. It also facilitates:
Links to organisations responsible for the facilities,
Association with relevant geographical areas,
Connection to scientific projects and oceanographic cruises.
