I agree Denise that one approach can be constraining - in practice it 
can also be dangerous - though don't want to deny the value of a shared 
infrastructre for supporting data sharing    (01)

Colleaguesdesigning software for safety compliance across oil and gas 
installations found that having one common model
actually made sites LESS safe. Being forced to implement systems that 
did not reflect the local context meant that in practice it increasingly 
necame the norm to disregard ALL of it. His approach was to define a 
common core that reflect fairly invariant features and have a formally 
documented locally managed version that reflected the needs and 
affordances of the local domain and the local workforce.    (02)
