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 model.

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

Luc

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