FACategory

FACategory is a formal classification scheme used to organize items, capabilities, or actions by function within a system. It is designed to support software architecture, data governance, and knowledge management by grouping related features into a stable taxonomy that can be cited in design documents and metadata.

Structure: A FACategory model typically comprises top-level categories that describe broad functional domains, followed by subcategories that specify more precise activities. Each category may include attributes such as scope, prerequisites, permissions, input and output data, and invariants. The model favors functional granularity and reusability, enabling consistent tagging across modules and datasets.

Applications: In software development, FACategory facilitates API design, component discovery, and feature tagging. In data governance, it supports access control, auditing, and policy enforcement by making functional capabilities explicit. User interfaces may use FACategory to organize controls and help content.

Examples: A top-level category could be "User Management" with subcategories such as "Create User," "Update User," "Delete User," "Assign Role." Another top-level could be "Reporting" with subcategories like "Generate Report," "Export Data."

Relation to other concepts: FACategory often intersects with ontologies, taxonomy management, and role-based access control. It is typically implemented as metadata alongside code or data, and can be extended as new capabilities arise. Critics note that lack of universal standards can hamper interoperability; proponents argue it reduces ambiguity and speeds integration.
