Thanks Kingsley!  So when I added the primary key, I was thinking of RDBMs
which work quite on a per table basis.  I guess you're an expert on that.
What's the logic around globally unique vs primary key.  I think what I
want to emphasis is joins, linking, and interoperability.  Appreciate the
update in text tho!

I wanted to emphasize the EAV model here, and links.  So I thought that's
your preferred mental model?

Agree with that further separation, but perhaps that could be in a separate
architectural explainer, because identity is difficult enough on its own.
Especially to obtain systems across different protocols that can work
together
