FIGI — Eliminate replication of individuals

The individuals present in pricing sources and security types were also present, at least in part, in the main ontology. Given that the main ontology is imported by both pricing sources and security types, this is entirely redundant and creates the real possibility that the two lists will be out of sych. Removing the individuals from the main ontology is the right approach.

Eliminate unnecessary replication of individuals in machine readable files.

This only affect machine readable files. Individuals representing both Pricing Sources and Security Types were present in both their respective ontology files as well as in the FinancialInstrumentIdentifier.rdf file. The task here is to simply remove all individuals that are representations of Pricing Sources or Security Types from the FinancialInstrumentIdentifier.rdf file.
