Data Catalog
Definition
Data catalogs act as an index of datasets, using metadata to describe the content and location of data. As opposed to a repository that stores the data in one place, a data catalog describes data wherever it is stored. Data catalogs may also describe restricted data, outlining how a person can apply for access to data that is restricted due to ethical or legal reasons.
Examples
NYU Data Catalog describes datasets, their location, and any access restrictions: https://datacatalog.med.nyu.edu
Health Data Gateway is a data catalog for biomedical data generated in the United Kingdom: https://www.healthdatagateway.org
