Defined in:
app/models/identifier.rb

Overview

An Identifier is the information that can be use to differentiate concepts. If an identifier differentiates individuals of all types it is “Global”. If an identifier differentiates individuals of one type, within a specific subset of that type, it is “Local”.

Local identifiers have a namespace, a string that preceeds the variable portion of the identifier.

Note this definition is presently very narrow, and that an identifier can in practice be used for a lot more than differentiation (i.e. it can often be resolved etc.).

!! Identifiers should always be created in the context of the the object they identify, see spec/lib/identifier_spec.rb for examples !!
