I was also thinking about this under the name of "state" of a resource, 
defined under a set of properties and a set of acceptable values for each 
property.

I agree that it's natural to "index" resources that satisfy selected criteria 
under a class. 

However, I find the use of the word "context" unsuitable and confusing. Then 
again that's just me; my choice of "state" comes mainly from wanting to match 
properties of certain values when those change over time, usually 
periodically.

Kindest regards,
