Report on the EIFFEL Ontology

The deliverable makes a thorough analysis of the EO domain, related semantics, and projects and implements an EIFFEL ontology (EIFF-O) in a modular way by combining various aspects:

• The ECV taxonomy focuses on the Essential Climate Variables (ECVs) specified by the GCOS (Global Climate Observing System) community. 
• The SDG taxonomy focuses on the Sustainable Development Goals as defined by the United Nations (UN). 
• The EO taxonomy mainly focuses on the two different EO perspectives: (i) the market perspective as perceived by users, and: (i) the thematic perspective as perceived by the (data) providers. 
• The EIFF-O ontology acts as a wrapper from the previous ontologies and provides a way of defining and discovering EO applications, datasets providers, and documents to users.
