Media type name: application

Media subtype name: vnd.writerslogic.pop+cbor

Required parameters: N/A

Optional parameters: N/A

Encoding considerations: binary

As a CBOR format, it contains NUL octets and non-line-oriented data.

Security considerations: This media type contains cryptographically anchored evidence of authorship process. It does not contain active or executable content. Integrity is ensured via a HMAC-SHA256 checkpoint chain and Verifiable Delay Functions (VDFs). Privacy is maintained through author-controlled salting of content hashes as defined in the spec. Security considerations of CBOR (RFC 8949) apply.

Interoperability considerations: While the +cbor suffix allows generic parsing, full semantic validation and behavioral forensic analysis require a witnessd-compatible processor as defined in the published specification.

Published specification: https://writerslogic.com/rats/pop/spec/1.3.0/

Applications which use this media: Generation of digital authorship evidence by the witnessd suite and WritersLogic integrated editors.

Fragment identifier considerations: N/A

Restrictions on usage: N/A

Provisional registration? (standards tree only): No

Additional information:

1. Deprecated alias names for this type: N/A
2. Magic number(s): 0xd950505020

General Comments: This registration is part of a coordinated suite of identifiers for the Proof of Process (PoP) protocol, including IANA CBOR Tag 1347571280 [for .pop] / 1463894560 [for .war]. The protocol follows the IETF Remote Attestation Procedures (RATS) architecture. Development and benchmarking are actively supported for the PAN@CLEF 2026 competition on authorship verification.

While initially utilized within the WritersLogic ecosystem, the specification is open for implementation by any platform requiring robust authorship attestation.
