Ok. Thanks for that, and sorry about the confusion.

BTW, I was wondering whether the proposal could be extended to  
include very easy keys for classes. This covers a use case I have,  
similar to the other bioinformatics ones, except where the entities  
are represented as classes.

It would be sufficient to have class keys be global. Same keys would  
imply equivalentClasses as opposed to sameIndividuals

classKeyPropertyExpression := dataPropertyExpression |   
classKeyAxiom := 'ClassKey' '(' { annotation} keyPropertyExpression  
{ keyPropertyExpression }')'



I think this could be accomplished as a preprocessing step to compute  
the equivalent classes before any (harder) reasoning starts.
