Subject: Referencing software in Registry relationships

Dear Registry, dear DCP,

[DCP because of identifier schemes]

During DocRegExt RFC, Gilles has made the point that machine-readably
declaring what tools a tutorial (or whatever) uses would be
desirable.  I have avoided this topic because software registration
has been a painful topic each time it has come up in Registry.  But
in the current context, it occurred to me that ASCL is there (and has
been there for a long time) and is probably enough to cover that
particular use case.

I have thus created this bug against DocRegExt:
<https://github.com/ivoa-std/DocRegExt/issues/4>.

If nobody has strong objections against it, I'd amend DocRegExt (and
also VOResource, which lists canonical URI schemes in altIdentifier)
some time next week.

So... are there objections?  Or is there support for the idea?

Thanks,

          Markus
