Hi Jack,
we may have added exactly what you are referring to in 4.5. There will
be a new feature called "dynamic ranges" that has been designed for
scenarios such as:
- there is a class ex:Address
- with a property ex:country
- and a property ex:state
If the user switches ex:country to ex:Australia then the range of
ex:state is assumed to be ex:ACT, ex:NSW, ex:NT, etc while for ex:USA it
would only allow the US states. This is implemented via a SPIN extension
that includes a SPIN template to be used as a spin:constraint at
owl:Thing. The UI (SWA components) will also understand how to treat
those automatically - and switch to another drop down box depending on
the selected country. Currently these dynamic ranges are limited to
enumerations, e.g. instances of state.
I have attached an example of this design.
How does this scenario compare to what you need?

I was wondering if TBC supports the notion of value dependencies. For
example, I might want to say the following:
if <someClass>.<someProperty> has a value, then
<thisClass>.<someOtherProperty> must be in this range
otherwise <thisClass>.<someOtherProperty> must be in this other range.
I have written it as a rule because dependencies generally look like
rules. Does SPIN allow us to capture these kinds of dependencies?
