McCool: detailed issues on signature?
Kaz: on TD issue 1151
[12]TD Issue 1151
[12] https://github.com/w3c/wot-thing-description/pull/1151
<McCool> [13]https://github.com/w3c/wot-thing-description/pull/
1151#issuecomment-913621245

1. (Kaz) Set up a repo for the new document. Something generic
like enveloped-json-signatures; note, not associated with wot.
If using wot prefix is required, then it can be
wot-enveloped-json-signatures (or how about wot-ejs, since will
be easier to share).
2. (McCool) Extract the current spec for signatures and put it
in a separate document. Will just copy the TD spec, delete
everything not related to signatures, make it a W3C (Draft)
Note, etc.
3. (McCool) Cleanup, following Oliver's suggestions. In
particular, relate explicitly to XML Signatures and JWS,
explain motivation, put in tables to compare and map features,
etc.
4. (Kaz, McCool) Reach out to W3C TAG to discuss.
5. (Oliver, McCool) Reach out to IETF, JOSE/COSE/JWS community
to get alignment, and converge on a standard. IETF 112 is Nov
6-12, and/or we could invite someone (Carsten Bormann would be
good to reach out to) to our F2F.
We still want implementations for IETF "working code" process.
Need at least one to drive discussion at IETF, two if we want
to proceed to a W3C REC. Two would be a good idea to test
interop even if doing an IETF RFC.
Discuss (e.g. at F2F) whether this should go into our next WoT
WG charter. McCool's opinion: not critical to be in our charter
if our goal is to make it an IETF RFC that we can just cite,
then our only action will be to cite it for TD 2.0. For TD 1.x
it would be optional/experimental and invokable by using an
extension vocabulary.
