Party Reference

Go up to Terms and Definitions

A Party Reference associates information with an existing Party without copying or replacing the authoritative information describing that Party.

A Party Reference contains or uses sufficient information to distinguish and, when applicable, resolve the referenced Party. This information may include:

• A Party Identifier
• The identifier scheme
• The assigning authority
• The scope within which the Identifier is unique
• A version or effective date
• Resolution information

The applicable Information Structure Definition determines which information the Party Reference requires.

A Party Reference remains distinct from a Party Identifier. A Party Identifier supplies a value used to distinguish a Party within a defined scope. A Party Reference uses an Identifier or another resolution mechanism to associate one information structure with the referenced Party.

A Party Reference also remains distinct from the referenced Party. Changing a Party Reference does not change the authoritative Party information unless the applicable operation explicitly modifies that information.

A Person acts on behalf of Example Bank in an FX Trade.

The applicable Role Assignment contains:

• A Party Reference identifying the Person
• A Party Reference identifying Example Bank

The two Party References allow a system to distinguish the Person performing the Role from the Party represented by the Person.
