Hi Darius As this is pretty fundamental I want to add this in to our schema Presumably this is intended to be specialized from the ClassifiedIdentification? template I believe you discussed this in yesterdays modeling meeting but I missed most of it so please bear with me ClassifiedIdentification?(a, b, c) means that b is a string and c a type of name assignment, and that b is a c-type name for a.

Roles:

1 hasObject Thing 
2 valIdentifier ExpressString 
3 hasContext ClassOfClassOfIdentification 

I noticed that the roles on the template in iring were

hasObject
valIdentifier
hasIdentificationType

Am I correct in assuming that it is role 3 that you are constraining ? If so what Role Value will you be expecting from the WIP either TAG NUMBER or TAG IDENTIFICATION CODE seem reasonable fits
