17 17  The following rules are a more formal definition of the way the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] agency system works:
18 18  
19 19  1. Agencies are maintained in an [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]].
20 20  1. The [[maintenance agency>>doc:sdmx:Glossary.Maintenance agency.WebHome]] of the [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] must be registered as an Agency in a (different) [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] (the “parent” [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]]).
21 -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]].
22 -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]], thus allowing [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] be a [[maintenance agency>>doc:sdmx:Glossary.Maintenance agency.WebHome]]. Agencies in this (child) scheme can themselves maintain a single [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] and so on.
23 -1. The [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] cannot be versioned and so takes a default (% style="color:#e74c3c" %)version(%%) number of 1.0, and it cannot be made “final”.

24 24  1. There can be only one [[Agency Scheme>>doc:sdmx:Glossary.Agency scheme.WebHome]] maintained by any one Agency. It has a fixed Id of AGENCIES.
25 -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.

71 71  It is therefore the responsibility of the agency maintaining these structures that the structures can be accessed using the URL. If the URL cannot be used to retrieve the structure then it is possible that applications using the structures will not be able to process the information properly. It follows that the content of structureURL and serviceURL should be deemed to be resolvable in the long term.
