OMP Domain Profile: Cross-Sector High-Risk AI Accountability Under the
Colorado Artificial Intelligence Act (SB 24-205) and Alignment with NIST
AI RMF 1.0
draft-veridom-omp-coloai-00
Abstract
This document defines a domain profile of the Operating Model
Protocol (OMP) for high-risk AI systems subject to the Colorado
Artificial Intelligence Act (SB 24-205, effective June 1, 2026),
which requires deployers of high-risk AI systems in consequential
decisions affecting Colorado consumers to implement risk management
programmes, provide consumer disclosures, conduct impact assessments,
and implement discrimination mitigation measures.
The profile -- designated ColoradoMark -- specifies how OMP's
deterministic routing invariant, Watchtower enforcement framework,
and three-layer cryptographic integrity architecture satisfy the
Colorado AI Act's per-decision accountability obligations and align
with the NIST AI RMF 1.0, providing a unified cross-sector
accountability evidence architecture for the six Colorado AI Act
consequential decision domains.
The OMP core specification is defined in the Operating Model Protocol
Internet-Draft (draft-veridom-omp).
Status of This Memo
This Internet-Draft is submitted in full conformance with the

1. Introduction
This document specifies the ColoradoMark domain profile for OMP,
covering high-risk AI systems under the Colorado Artificial
Intelligence Act (SB 24-205) [CO-SB-24-205], which requires deployers
of high-risk AI in consequential decisions to implement risk
management programmes aligned with the NIST AI RMF 1.0 [NIST-AI-RMF].
The full specification is provided in the plain-text version of this
Internet-Draft.
ColoradoMark addresses the six Colorado AI Act consequential decision
domains, including employment (see also [I-D.veridom-omp-employ]),
housing finance (see also [I-D.veridom-omp-fhfa]), healthcare (see
also [I-D.veridom-omp-clinical]), and cross-jurisdiction EU AI Act
obligations (see also [I-D.veridom-omp-euaia]). Audit Trace payloads
are canonicalized per [RFC8785]. Audit Traces are timestamped per
[RFC3161]. Sealed Audit Traces are verifiable using the OMP
Reference Validator [OMP-OPEN-CORE]. The OMP specification is also
archived at [ZENODO-OMP].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119] [RFC8174].

2. Profile Specification
The complete profile specification -- including all terminology,
regulatory framework analysis, routing state definitions, Watchtower
definitions, Audit Trace schema extensions, deployment category
mappings, invariant definition, and security considerations -- is
provided in the companion plain-text specification for this Internet-
Draft. This XML rendition provides the structured metadata,
references, and IANA considerations for the IETF Datatracker and
xml2rfc processing pipeline.
3. The Profile Invariant
Implementations of this profile MUST satisfy the two-property
invariant specified in the plain-text companion document: (1) every
consequential AI decision generates a sealed Audit Trace documenting
the decision, human oversight applied, and applicable regulatory
evidence fields; and (2) the Audit Trace is sealed with the three-
layer integrity architecture defined in [I-D.veridom-omp] Section 7,
detectable as modified by any third party without access to the
operator's infrastructure.
4. Security Considerations
The security considerations of [I-D.veridom-omp] apply in full.
Operators MUST implement appropriate access controls and data
protection measures for Audit Trace storage, access, and disclosure
consistent with applicable jurisdiction law.
5. IANA Considerations
This document has no IANA actions.
