What is EDAM?

EDAM is a comprehensive ontology of well-established, familiar concepts that are prevalent within bioinformatics and computational biology, including types of data and data identifiers, data formats, operations and topics. EDAM provides a set of concepts with preferred terms and synonyms, definitions, and other information - organised into a simple and intuitive hierarchy for convenient use (see figure).
