[Obi-protocol-application-branch] Study design execution and performance

[Alan Ruttenberg]

For reasons that I don't quite understand yet, dropping the has_part
axioms on Study design execution increase Pellet reasoning performance
by a factor of 10.

I'd like to drop them for the moment. Perhaps put them in a comment
and return to them after we've figured out what the deal is.

In reviewing terms nearby I also noticed:

'study participant role' is_concretization_of some 'study design'

I don't think that's right, though it's a bit squishy to put my finger
on it. I think it's because the concretization of a gdp is a kind of
copy of it, and the concretization happens in the entity that has the
copy.

Ok with me.

Agreed.

we have been working on this for some time. the study participant role
is defined by the study design. i needed a process for
realizing-role-defined-in-study-design and we came up with
is_concretization_of. other suggestions are welcome!! we just do not
want to have multiple parallel heirarchies in OBI -- a set of roles with
parallel processes with parallel designs.

I thought what we wanted to have is:

study participant is_realized_in only (is_concretization_of some study
design)

i agree; but we were seeing a question from Alan

[Bjoern Peters]

The question was about the direct relation between study design and the
study participant role. I believe what Alan wants is the more
complicated version, which by the way I screwed up:

study participant role is_realized_in only (realization_of (is_concretization_of some study
design))

Which we can now short cut with:

study participant role is_realized_in only 'study design execution'

thanks! i will make that change.
