No I think we are basically on the same page.

I'm glad you brought that up.  I do think we have the 
expressiveness in OWL (and in Description Logics, 
generally) to model term alignment (equivalent classes/properties,
  inverse roles, value restrictions, etc..) as a seperate ontology
This would refer to (and therefore owl:import) the HCLS-Experiment 
ontology ( to ground the mapping semantically not just for annotation 
purposes ).

You can then either have the instance graphs that depend on the Gel/BOSS associate
with this term mapping (expressed as an OWL ontology) with 
rdfs:isDefinedBy, or have the Gel ontology import this lingua franca 
ontology directly.  Just some thoughts.  Not a trivial proposition, but we 
have sufficient expressiveness to capture this kind of web ontology 
management pattern (and others like it).
