Hi Kathleen, hi SACM, SUIT & RATS list, the corresponding *SWID authors discussed this issue and are proposing: > https://github.com/ietf-rats-wg/eat/issues/46 This includes an extended scope to include the option of SUIT Manifest related Claim values, next to various *SWID Claim values. We permutated "signed" & "not-signed" as well as "payload tags" and "evidence tags" for *SWID tags in this proposal. The authors are convinced that the "not-signed" variants are of essence (as CWT does not allow "not-signed CBOR items", but also do not imply any implications to the SUIT Manifest Claim definition (although there are strong similarities and there could be some). The current *SWID contributors prefer this contribution as a parallel effort to the EAT I-D, SUIT Manifest I-D, the CoSWID I-D and existing ISO XML SWID standard. This proposal includes the primitive to not delay corresponding IETG I-D in their respective WGs. Having said that, we would like to get feedback for the proposal references above. If there is no dissent or push-back on either the SUIT, SACM, and RATS lists, our proposed way forward is a unified creation of EAT Claim Sets in the RATS WG that enables the use of various *SWID variants & the SUIT Manifest as payloads for RATS via the RATS EAT I-D. In summary, we would like to create this interop I-D in concert and welcome every joint effort in this domain.
