The Common Data Model (CDM) is the formal description of the EU institution's official documents, legislative decision-making process, and its related publications.
More specifically, the CDM describes documents in the legal domain (e.g., the Official Journal, case law, consolidated legislation, preparatory acts, etc.), general publications (e.g., reports, periodical serials, books, brochures, etc.), the different entities related to their creation (e.g., the agent who wrote the document, the procedure and event of which it is the result, etc.), and their relations.
The model is based on the FRBR methodology which is well suited to describe multilingual and multiformat publications.
This model is continually refined in collaboration with the business units to guarantee its quality with regards to the institutions’ needs for the structure of their metadata.
