Hi Jacques,

to add my 2 cents:

Option A will not make it, i.e. we do not plan to rely on a "by convention
name matching" mechanism. IMO, the meaning of requirements must lie in the
metadata like what kind of thing is referred to and/or what kind of
relationship is used. We listed it in the current draft more as kind of a
counter-example to explicitly tell people this it _not_ how it works.

I think Option B and C will make it. Option C is actually the most specific
one, i.e. with most information, but you only need to define as much detail
if needed. That is, the additional specification is optional. That said, we
can still have a very short notation as shown in Option A, i.e. only one
line, but not implying magic name matching. The only implication of such a
one line notation would be: if the orchestrator cannot derive the type of
relationship to use, it will just assume a generic "DependsOn" link.

Regards,
Thomas

Thanks Jacques,

We can review your comments at our next opportunity; however, I believe
that we are going to allow all 3 options to be viable (depending on
context) and will have to make that clearer in the next set of revisions.
Although Option A, IMO still leaves room for some ambiguity which we should
discuss further, it does allow for simpler notation for hosting
relationships.

For our normative types, I believe I would very much like to use Option B
to be completely clear that relationships are HostedOn, etc. and would go a
long way to readers of the spec. and implementers as well.  We have already
run into an implementer case where it was hard for them to see the exact
use case where WebApp was hosted on WebServer by the implied use of the
name "host" for the requirement.

Kind regards,
Matt

Not sure if there is a TOSCA issue associated with that draft, so sending
back a few comments inline  on the 3 options under D.1.1 (I prefer Option
C…) in new Appendix D  as response to this email (the attached draft is
small enough).
Thanks,
