okay, cool, maybe I will be able to help with this!  This ontology here 
(https://github.com/SDG-InterfaceOntology/sdgio) seems to have as part of 
it a lot of ontological relations between logical statement types and 
definitions like this one that could be encoded in Atomese: 

Definition: B occurs_in c =def b is a
  process and c is a material entity or immaterial entity&
  there exists a spatiotemporal region r and b
  occupies_spatiotemporal_region r.& forall(t) if b exists_at t
  then c exists_at t & there exist spatial regions s and
  s’ where & b spatially_projects_onto s at t& c is
  occupies_spatial_region s’ at t& s is a
  proper_continuant_part_of s’ at t

I can help be encoding those in Scheme and the ontology can then connect 
then to others via relations such as 'sub-property' etc.
