I-ADOPT aims to facilitate data interoperability by offering a common framework to describe variables and connect terminologies used to name variables based on an ontology.
The I-ADOPT recommendations, endorsed by RDA, are now a candidate extension for the OGC OMS (OGC Observations, Measurements, and Samples/ISO 19156) standard. I-ADOPT could be implemented as an OMS extension for the observable property concept, providing richer and FAIRer representation of what is observed in an observation event.
