Propose that 'is' be dropped from all predicates that have a suffix. Two
reasons - parsimony and connotations (in fact denotations) about tense are


            Example: 'isDerivedFrom' becomes  'derivedFrom'.


Also advocate that all predicates begin with a lowercase letter.

Hi Daniel and Simon,

In the conceptual model (up to section 5), all relations use present tense,
uses, isDerivedFrom, isComplementOf, isGeneratedBy, ...

I agree with Daniel, we need consistency in the conceptual model and formal

I agree with Simon, it's nice to point back into the past.


PS. I took as an action to poll about the use of tense.

+1 for "used", for the reasons you give.
-1 for "isUsedBy". All other relations in the model link effect/later
occurrence to cause/earlier occurrence, so "isUsedBy" would be
inconsistent. This means that provenance graphs would not consistently
point back into the past of the thing we're seeing the provenance of,
and would be confusing to iteratively navigate.
