What is the difference between a catalogue and a dataset?

A Catalogue can have two definitions, comprising: 1. data or 2. metadata.

  1. A data Catalogue (or Catalog) is a curated collection of datasets and data services that are managed and published by an organisation or entity.

  2. A data catalogue is a curated collection of metadata about datasets that are managed and published by an organisation or entity.

A Dataset is a collection of data, published or curated by a single source, and available for access or download in one or more formats.

Within the context of the EHDS (European Health Data Space) Regulation proposal [EUR-Lex 52022PC0197 (Art.44)], access to such datasets must adhere to principles of data minimisation and purpose limitation. This ensures that only the data relevant and necessary for specific processing purposes is provided. This data can be in either anonymised or pseudonymised format depending on the feasibility of achieving the processing objectives.
