Figure 2 of ISO 8000-100 gives the architecture for master data as a set of relationships: master data carry information on their provenance, accuracy and completeness; they are coded with concepts taken from a data dictionary; they meet a data specification and a formal syntax. A data specification sets the requirements for coding master data with dictionary concepts, sets the preferred terms for those concepts and requires a formal syntax to be used. Data dictionaries, data specifications and master data all take their identifiers from an identification scheme. The standard notes that the architecture may apply more widely and that a general version was meant for ISO/TS 8000-1.
