Agency Scheme V10
Contents
Overview
An Agency Scheme is a container for maintenance Agencies and is a type of Organsiation Scheme. Agencies own and maintain Maintainable structures.
In SDMX the Agency Scheme contains a non-hierarchic list of maintenance agencies. Each maintenance agency can have a single Agency Scheme, and may have none. The agencies in the Agency Scheme are deemed to be sub agencies of the maintenance agency of the scheme in which they reside.
The top-level Agency Scheme is the scheme for which SDMX is the maintenance agency (SDMX Agency Scheme), and every Agency in every Agency Scheme must be related directly or indirectly via intervening Agency Schemes, to an Agency registered in the SDMX Agency Scheme. In this way each Agency can be identified uniquely by the combination of Agencies in the path from the SDMX Agency Scheme to the Agency Scheme in which it resides, plus its own identity in that scheme

Identity
The diagram in the SDMX_2_1_Section_6_TechnicalNotes_2020-07 pdf file illustrates this hierarchical structure of the agencyID:
In the Registry, the SDMX Agency Scheme uses the prefix of SDMX and has The Identity of AGENCIES and the Name SDMX Agency Scheme. This will hold all the Agencies created in the Registry.
If a Sub Agency is created the prefix becomes the ID of the owning agency, with an ID of AGENCIES and the Name of AGENCIES as shown in the second image.
