Hi - whilst I'm not as familiar with the details the amount of modules and
the logical structure fit my expectation.  I think however that the
explanations of these will need some work to make them accessible. In
particular sosa-om and sosa-sam explanations only help if you are
intimately familiar with these. It would help even at this early stage to
perhaps describe what these contain, and why they are not part of the core.
If what they are is an extension of sosa-core that does not define new
entities, but uses additional expressivity available in a language then
perhaps we can come up with a naming convention that reflects the role of
each module? eg sosa-ssn-align ?

If modules are doing multiple things - like extending scope, adding axioms
and performing alignments (declaring equivalent classes) then this is a
departure from Krzysztof's proposal - which may not be a bad thing but
means that the modularisation strategy needs to be re-articulated and taken
into account.
