extensibility of CM indicators? #26

Closed thomas-fossati closed 9 months ago

thomas-fossati commented 1 year ago

Policies (for evidence and attestation results) as well as trust anchors are other CMs that we may want to support.

We should think whether we want the CM-IND bitmask to be extensible - e.g., via

cm-type /= &(
  yacm: bit_position
)

or we just capture all the existing CM in the RATS architecture and seal it once and for all.

I believe it should be extensible so that a future revision of the architecture that needed to define more clearly hybrid roles such as verifier to verifier or lead attester to verifier where partially processed or intermediate results are forwarded. This may include forwarding appraisal policies which currently isn't defined in cm-type due to WG scope, but is defined in the architecture.

I'm fine with this, it looks like a sensible approach. It's only a bit more hassle to handle the IANA registry :-)
