Phạm vi áp dụng / Scope of standard

Overview

The development of the Financial Instrument Global Identifier originated from a need for a standard methodology to bridge across multiple identification systems for financial instruments. Without prejudice against any existing symbolbased solutions, or any question of the validity of one system over the other, the FIGI standard utilizes a metadata driven approach to enable the unique and persistent identification of financial instruments. In so doing, while employing the principles of open data, it provides a mechanism for interoperability between existing identification systems.

This specification lays out the details of the Financial Instrument Global Identifier across two dimensions:

1. The specification of the structure of the Global Identifier itself-what is/is not valid as a Global Identifier and how a Global Identifier is constructed and validated.

2. An ontological model specifying the relationship between the Global Identifier and other closely related information.

This specification has been created with the clear understanding that a published interface for creating identifiers and linking together relevant parties, e.g., Certified Providers or the Registration Authority, through the use of technology is a critical part of the implementation of this standard. While high level descriptions of the various types of organizations that need to be involved as well as high level descriptions of the interactions between such organizations has been included in this document, they are included on the understanding that there will need to be a subsequent specification produced that details the necessary technical infrastructures and service level agreements for all participating organizations. To be clear, the technical specification of those services and service level agreements is out of scope for this document.

Global Identifier concepts are documented using two forms of definition:

1. A structured ontology specification of the concept, and its relationships to others, represented using the Web Ontology Language (OWL), in the form of (a) RDF/XML serialized OWL, (b) ODM (Ontology Definition Metamodel)-compliant ODM XMI, and (c) ODM-compliant UML XMI.

2. Natural language definitions which represent the concepts in natural language using the vocabulary of the finance industry.

3. Two controlled vocabularies in rdf format, one specifying the list of possible values for security types, one specifying the list of possible values for pricing sources. These lists are subject to growth over time as new security types are either invented or incorporated into FIGI and as new pricing sources are taken into account. These may, but are not required to, include references to other existing or future standards, such as those developed by ISO, W3C, OMG or others.

This specification covers both the content of the models, and the underlying architecture employed for producing and presenting the model.

This model is developed from a previously existing infrastructure that had issued in excess of 150 million FIGIcompliant identifiers as of the 2014 OMG publication of the original specification. The purpose of this specification is to specify the structure of the Identifier itself and its relationship to key information elements rather than to specify the technology and related interfaces used to generate, access, and manage the identifiers.
