data dictionary Collection of descriptions of the data objects or items in a data model. After each data object or item is given a descriptive name, its relationship is described (or it becomes part of some structure that implicitly describes relationship), the type of data (such as text or image or binary value) is described, possible predefined values are listed, and a brief textual description is provided. This collection can be organised for reference into a data dictionary. https://orcid.org/0000-0002-5214-4466 https://orcid.org/0000-0003-2687-1982 data stewardship technical concept
