The Operational/survival model seems to better structured now. By having One supercalass you mean a class like OperationModel and then two sub-classes as SurvivalRange and OperatingRange?

I looked up some commercial sensor factsheets and tried to see how many of their attributes can be specified with the current operation model; it seems most of the common attributes could be defined under existing classes in the model. There were also attributes such as:

- electromagnetic interference (EMI) range, salt water and solvents effect, Chemical resistance (which I think will be under environmental survival range)

- Calibration cycle (which could be an attribute in Maintanance schedule)

and: Response time, Repeatability (which are probably a part of Quality of Information attributes?)

Yes, they aren't linked.  I wasn't sure that there was anything to
say.  If we are to just have the same name for all the roles in that
diagram, then there doesn't seem to be any restriction to add that
links things.

I had a look at restructuring things a little.  I put up an extra
diagram and some text on the wiki page


We could put things together under a single superclass as we did in
the modelling of accuracy and then constrain the condition based on
