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

EDAM is particularly suitable for semantic annotations and categorisation of diverse resources related to bioscientific data analysis: e.g. tools, workflows, or training materials. EDAM is also useful in data management, for recording provenance metadata of processed bioscientific data.

EDAM can be browsed online at the NCBO BioPortal, at OLS, and in the EDAM Browser.

The all-newest unstable version can be browsed and commented at the NCBO BioPortal and WebProtégé (free registration required).

The latest stable version is always downloable from http://edamontology.org/EDAM.owl | tsv | csv. For older versions, see http://edamontology.org/page#Download or /releases.

Comprehensive documentation and guidelines are available via readthedocs (maintained here).

A quick overview is at the https://edamontology.org home page.
