Dataset Metadata Model (DATMM)

DATMM is a linked data or semantic metadata model developed by NLM to provide information about biomedical datasets. DATMM leverages existing RDF (resource descriptive framework) ontologies and schemas to facilitate metadata harvesting and promote wide adoption. DATMM is designed to be a minimalist approach: defining individual research objects (the dataset, documentation, contributors, etc.), while relying on semantic relationships to both drive search and provide deliberate and serendipitous discovery. DATMM’s minimalist model will drive adoption and harmonization across repositories.
