| 3 | All [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] in [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] is owned and maintained by a [[maintenance agency>>doc:sdmx:Glossary.Maintenance agency.WebHome]] (Agency identified by agencyID in the schemas). It is vital to the integrity of the [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] that there are no conflicts in agencyID. In order to achieve this [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] adopts the following rules: | ||
| 4 | |||
| 5 | 1. Agencies are maintained in an [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] (which is a sub class of Organisation Scheme) | ||
| 6 | 1. The [[maintenance agency>>doc:sdmx:Glossary.Maintenance agency.WebHome]] of the [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] must also be declared in a (different) [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]]. | ||
| 7 | 1. The “top-(% style="color:#e74c3c" %)level(%%)” agency is [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] and this [[agency scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] is maintained by [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]. | ||
| 8 | 1. Agencies registered in the top-(% style="color:#e74c3c" %)level(%%) scheme can themselves maintain a single [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]]. [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] is an agency in the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] [[agency scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]]. Agencies in this scheme can themselves maintain a single [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] and so on. | ||
| 9 | 1. The AgencyScheme cannot be versioned and so take a default (% style="color:#e74c3c" %)version(%%) number of 1.0 and cannot be made “final”. | ||
| 10 | 1. There can be only one AgencyScheme maintained by any one Agency. It has a fixed Id of AgencyScheme. | ||
| 11 | 1. The format of the agency identifier is agencyId.agencyID etc. The top-(% style="color:#e74c3c" %)level(%%) agency in this identification mechanism is the agency registered in the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] [[agency scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]]. In other words, [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] is not a part of the hierarchical ID structure for agencies. [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] is, itself, a [[maintenance agency>>doc:sdmx:Glossary.Maintenance agency.WebHome]]. | ||
| 12 | |||
| 13 | This supports a hierarchical structure of agencyID. | ||
| 14 | |||
| 15 | An example is shown below. | ||

| 19 | **Figure 5: Example of Hierarchic Structure of Agencies** | ||
| 20 | |||
| 21 | Each agency is identified by its full [[hierarchy>>doc:sdmx:Glossary.Hierarchy.WebHome]] excluding [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]. | ||
| 22 | |||
| 23 | The XML representing this structure is shown below. | ||

| 35 | Each of these [[maintenance agencies>>doc:sdmx:Glossary.Maintenance agency.WebHome]] has an identical Codelist with the Id CL_BOP. However, each is uniquely identified by means of the hierarchic agency structure. |
