Subject Area

Subject areas are topics or domains of knowledge that are important to the organization. Typically, they cover data that is widely shared across the organization and there is business value in maintaining consistency in the data values in each copy.

The role of a subject area definition is to act as a collection point for all the subject area materials. This includes:

The materials that are part of the subject area are classified as such using the SubjectArea classification.

Each subject area has an owner (see SubjectAreaOwner) who is responsible for the materials relating to the subject area. Often the subject area owner is a senior person in the organization with expertise in the subject area. He/she coordinates other subject-matter experts to author and maintain the materials.

The SubjectAreaDefinition and appointment of a SubjectAreaOwner helps to coordinate the efforts to build the materials for each subject area.

Subject Area Content

The effort required to author and maintain these definitions, plus the governance process required to ensure they are used wherever appropriate is offset by the savings in managing and using the shared data associated with the subject area.

Subject Area Domain

Assets that are managed using the subject area's materials are said to be part of the subject area's domain. This is called the Subject Area Domain and is synonymous with Data Domain - although a subject area domain may manage assets that are not data assets (such as systems and infrastructure) which is why open metadata uses a more generic name.
