Status: Draft
Intended Status: Standards Track
Updates: RFC-PCS-0001, RFC-PCS-0002, RFC-PCS-0003, RFC-PCS-0004, RFC-PCS-0005
Expires: TBD
1. Abstract
This document defines the Persistra Cognitive Standard (PCS) Certification Program, including certification levels, certification processes, certification marks, and permitted usage.
The PCS Certification Program establishes a uniform mechanism for verifying, communicating, and maintaining conformance with PCS specifications.
2. Motivation
As PCS adoption grows, it becomes necessary to:
Certification marks provide a clear, enforceable signal of compliance without mandating a specific implementation.
3. Scope
This document governs:
This document does not mandate participation in the PCS Certification Program.
4. Definitions
Certification Authority (CA): The entity authorized to grant PCS certification
Certified Implementation: An implementation that has passed PCS-CTS
Certification Mark: A registered mark indicating PCS compliance
Conformance Suite: PCS-CTS as defined in RFC-PCS-0004
Normative language follows RFC 2119.
5. Certification Authority
5.1 Authority Designation
Persistra Inc. is the initial and sole Certification Authority for PCS.
The Certification Authority is responsible for:
5.2 Delegation
The Certification Authority MAY delegate testing or auditing functions to approved third parties.
Final certification decisions remain with the Certification Authority.
6. Certification Levels
PCS certification corresponds directly to PCS conformance levels:
Level Description
An implementation MAY be certified at one or more levels.
7. Certification Process
7.1 Application
Applicants MUST submit:
7.2 Testing
Certification requires successful execution of:
7.3 Attestation
Upon successful testing, the Certification Authority SHALL issue:
8. Certification Marks
8.1 Mark Definitions
Authorized certification marks include:
“PCS-L1 Certified”
“PCS-L2 Certified”
“PCS-L3 Certified”
“PCS-L4 Certified”
Marks MAY include graphical or textual variants.
8.2 Permitted Use
Certified implementations MAY:
Usage MUST accurately reflect the certified level.
8.3 Prohibited Use
Certification marks MUST NOT be used:
Unauthorized use constitutes trademark infringement.
9. Certification Validity and Renewal
9.1 Validity Period
PCS certification is valid for a defined period (e.g., 12 months).
9.2 Re-Certification
Re-certification is REQUIRED when:
10. Revocation
The Certification Authority MAY revoke certification if:
Revocation SHALL require removal of certification marks.
11. Fees
Certification MAY involve fees determined by the Certification Authority.
Fees MAY vary based on:
Fee structures SHOULD be transparent and non-discriminatory.
12. Relationship to Patents
12.1 Certification vs Licensing
12.2 Disclosure
Implementers are responsible for ensuring appropriate patent licenses for PCS implementation.
13. Security and Auditability
Certified implementations SHOULD:
Preserve PCS-CTS audit artifacts
Support independent verification
Protect provenance and policy records
14. Governance
The PCS Spec Editor maintains authority over:
15. IANA Considerations
This document defines no IANA actions.
16. Conclusion
The PCS Certification Program enables trustworthy adoption of persistent cognitive systems while preserving architectural freedom.
Certification provides clarity without mandating implementation, and trust without surrendering control.
