Interoperability Basis Platform

= 1 Introduction =

The registry schemas have been updated to reflect the various changes in the standard and to introduce new constructs for managing [[subscriptions>>doc:sdmx:Glossary.Subscription.WebHome]]. In addtion, the constructs that had existed for querying [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] have been removed as this is now handled by the query messages.

9

As was done with the query, the registry message set now contains distinct messages for each operation. The messages will eventually allow the registry to function in more standard web service mannter.

**RegistrationType:** Registration provides the information needed for data and [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]] set registration. A [[data source>>doc:sdmx:Glossary.Data source.WebHome]] must be supplied here if not already provided in the [[provision agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]]. The [[data set>>doc:sdmx:Glossary.Data set.WebHome]] or [[metadata set>>doc:sdmx:Glossary.Metadata set.WebHome]] must be associated with a [[provision agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]], a [[metadata flow>>doc:sdmx:Glossary.Metadataflow.WebHome]], or a [[dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]] definition. If possible, the [[provision agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] should be specified. Only in cases where this is not possible should the [[dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]] or [[metadata flow>>doc:sdmx:Glossary.Metadataflow.WebHome]] be used.

|id|IDType|The id [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] holds a registry assigned identification for the registration. This must be provided in a response message (unless an error occurred while submitting a new registration), and should be included when updating or deleting a registration.

45

|validFrom|xs:dateTime|The validFrom [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] provides an inclusive start date for providing supplemental validity information about the registration, so that data visibility from the registry can be controlled by the registrant.

46

The default value is false, and the [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] will always be assumed false when the [[provision agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] references a [[metadata flow>>doc:sdmx:Glossary.Metadataflow.WebHome]].

The default value is false, and the [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] will always be assumed false when the [[provision agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] references a [[metadata flow>>doc:sdmx:Glossary.Metadataflow.WebHome]].

The default action is Append. The Replace action is not applicable to final structures in the repository, and will produce an error condition, as these can be versioned but not modified.

For example, one may want to append all structural components of a structure message, save one codelist. This codelist could be referenced in a submitted structure element and given an action of Informational.|

339

340

**SubmittedStructureType:** SubmittedStructureType generally references a submitted structural object. When used in a submit structure request, its purpose is to override the default action or external dependency resolution behavior. If neither of these indicators are set, then it will be ignored. In a submit structure response, it is used to reference a submitted object for the purpose of providing a status for the submission. In this case, the action attribute should be populated in order to echo the requested action.

**StructuralRepositoryEventsType:** StructuralRepositoryEventsType details the structural events for the subscription. At least one maintenance agency must be specified, although it may be given a wildcard value (meaning the subscription is for the structural events of all agencies). This can also be a list of agencies to allow the subscription to subscribe the events of more than one agency. It should be noted that when doing so, all of the subsequent objects are assumed to apply to every agency in the list. The subscription is then refined by detailing the structural objects maintained by the agency for which the subscription should apply. It is possible to explicitly select all object events, all objects of given types, or to individually list out specific objects. Note that for any object, it is also possible to provide an explicit URN to reference a distinct object. In this case, the reference to maintenance agency described above is ignored. Although it is not required, if specific objects are being referenced by explicit URNs, it is good practice to list the agencies.
