Which Article 33 metadata and semantic assets must a data space participant publish under the EU Data Act?
Under the Data Act, an Article 33 participant offering data or data services must describe dataset content, use restrictions, licences, collection methodology, data quality, and uncertainty in machine-readable form, and describe data structures, formats, vocabularies, taxonomies, and code lists in a public and consistent way where available. These descriptions are what make a data-space offer interoperable.
A participant should also document technical access means such as APIs, terms of use, and quality of service, so another participant can consume the data without bespoke negotiation.
