working back through the thread ...

a profile should have have the same level of platform agnosticism as the
specification it is profiling...but may of course be a profile designed to
support a particular implementation platform.

Profiles may have one ore more relevant resources supporting implementation
specific platformas - such as SHACL constraints.

With respect to the spreadsheets defining profiles:
 Constraints on content in a general schema tend to be non-trivial - for
example "Temperature" might have constraints, for a particular purpose, on
what measurement methdology,  the units of measurement, the number of
significant decimal places, whether measurement error is reported etc.
Whilst you can describe such complex objects it requires trickery - either
a microformat (such as UML OCL) or magic knowledge about how columns are
used in conjunction with each other to build a constraint, what multiple
worksheets mean in relationship to each other etc...

But the goos news is that if, for some types of profiles, simple tabulation
of constraints is useful, it can easily be generated automatically from a
richer more flexible canonical form, and RDF compatible with DCAT,
constrained by a OWL or SHACL model - would be the obvious choice here.

The "primary audience" for application profiles informs us on the views we
need to generate - not the best way to manage the information. ( sounds
like a use case for content negotiation by profile :-)  )
