Re: New Work Item Proposal: Universal Wallet 2020

Everytime this comes up, I wonder why members of this community seem
opposed to the wikipedia definition:
https://en.wikipedia.org/wiki/Reference_implementation

Characteristics of a Reference Implementation:

   1. Developed concurrently with the specification and test suite;
   2. Verifies that specification is implementable;
   3. Enables the test suite to be tested;
   4. Serves as a Gold Standard against which other implementations can be
   measured;
   5. Helps to clarify the intent of the specification in situations
where conformance
   tests <https://en.wikipedia.org/wiki/Conformance_testing> are inadequate


Does W3C specifically discourage the use of the term "reference
implementation".... I assumed this was a common practice:
https://github.com/webofthings/webofthings.js

Regardless of the name, these are the characteristics I'm looking for. As
wikipedia notes, "sample" or "model" implementation are less
frequently used terms for the same thing.

There are some conformance tests, and I can see a lot of value in keeping
them next to the spec and "sample implementation", I'm generally a fan of
starting with a mono repo and splitting things up when it becomes obvious
that it is the right thing to do because there is too much contribution for
one repo to handle, or because sub components are getting consumed
independently almost as frequently as they are getting consumed together.

If there is reason to believe there will be more contribution overall if
the "sample implementation" is also in W3C CCG repos, I'm happy to do
that... I saw splitting them up as a potential opportunity to
engage multiple communities and AFAIK you can contribute to Apache 2.0
software regardless of the github organization that hosts it, for example:
https://github.com/adobe/experience-platform-dsw-reference is also Apache
2.0 with a CLA...

Leonard, should I interpret your strong desire that "an example
implementation" stay in CCG as an indication of a strong desire / plan to
contribute to it here?
