According to TOGAF, the recommended dimensions used to define the scope of an architecture include all the following, except:

Architecture Domains (Business, Data, Application, Technology) are a fundamental dimension for defining what parts of the architecture are in scope.

Enterprise Focus defines which parts of the enterprise (e.g., a specific division, the whole enterprise) are included in the architecture scope.

Level of Detail specifies the granularity at which the architecture is described, from high-level conceptual to detailed logical or physical.

TOGAF explicitly defines the dimensions for scoping an architecture as: Time Period, Architecture Domains (Business, Data, Application, Technology), Level of Detail, and Enterprise Focus. 'Subject Matter' is a broad term that would encompass aspects of the other domains but is not listed as a formal, distinct scoping dimension in TOGAF.

Time Period defines whether the architecture pertains to the baseline (current) state, the target (future) state, or transition architectures.
