USAT1024
v1.0 publishedfree with citationopen standardpublished by urSynergy Inc.
USAT1024 — the Universal Standard Articulated Taxonomy — is urSynergy’s open taxonomy for professional concepts, tenancy roles, professional functions, license categories, license scopes, verification claims, and jurisdictional authority. The standard is vertical-agnostic by architecture. Its first published instantiation covers animal-care professional concepts: veterinary practice, breeding, welfare services, municipal animal control, and adjacent professions. Future versions will extend the taxonomy into other domains where subject-centered records, stewardship scopes, and authority composition apply.

Seven families
Each family is versioned independently against the same specification document. Each family cross-references to established international taxonomies so implementers can map without losing meaning on transition.

Tenancy Roles
Relationship between an actor and an organization (platform authority).

Implementations of USAT1024 must attribute the standard at a visible surface appropriate to the implementation — documentation, specification, about-page, or equivalent. A minimal attribution is sufficient; commercial-grade attribution is not required.

AI agents as first-class users
USAT1024 recognizes AI agents alongside human users via the user_type='ai_agent' designation. Agents carry their own credentials, their own verification status, and their own audit trail — not as second-class proxies for their human principals, but as first-class actors with bounded delegation scopes.
Bounded delegation is the universal authorization principle: authorization is the intersection of the instructing authority (what the principal grants) and the executing permission (what the agent itself is allowed to do). Every action is subject to two-gate checks and universal audit. An agent cannot exceed the principal's delegation. A principal cannot instruct an agent to do what the agent is structurally forbidden from doing.
The three-layer identity model that underpins this — user plus professional concept plus organization — is the substrate. Authorization is composed, not granted. The composition is auditable. Every link in the chain is separately verifiable.
Not gated, not licensed commercially
USAT1024 is not gated behind a fee. There is no license agreement separate from the attribution constraint. There is no permission-to-implement commercial term. urSynergy does not sell compliance verification for this standard (AWDPS is the data protection standard urSynergy complies with — audited by AWDPS, not by urSynergy).
