How the catalog describes a dataset

Every record in the catalog is described with the DATaset Metadata Model (DATMM). It connects a dataset to where it lives, who made it, what funded it and what it is about — so you can search across repositories in one place.

datmm:Dataset
A single catalogued dataset — the record everything else describes.
datmm:Repository
The archive the dataset lives in, such as ClinicalTrials.gov.
schema:Grant
The award that funded the work behind the dataset.
datmm:Documentation
Articles and readme files that describe the dataset.
bf:Contribution
A contributor paired with the role they played.
skos:Concept
A subject term, drawn from vocabularies such as MeSH.
foaf:Agent
The person or organisation behind a contribution.
dcmitype:Collection
A grouping of related datasets, which may nest inside another.
