SDMX Registration Registry Module The registration registry module defines the constructs that are used for the maintenance and discovery of data and reference metadata in a registry. SubmitRegistrationsRequestType defines the payload of a request message used to submit addtions, updates, or deletions of data/metadata set registrations. RegistrationRequest provides the details of a requested registration and the action to take on it. A reference to a provision agreement that exists in the registry must be provide along with a simple and/or queryable data source. The id should only be provided when updating or deleting a registration. RegistrationRequestType describes the structure of a single registration request. It contains the details of a registation and an action field to indicate the action to be taken on the contained registration. Registration contains the details of the data/metadata set registration to be added, updated, or deleted. The action attribute indicates whether this is an addition, a modification, or a deletion of a registration. SubmitRegistrationsResponseType describes the structure of a registration response. For each submitted registration in the request, a registration status is provided. The status elements should be provided in the same order as the submitted registrations, although each status will echo the request to ensure accurate processing of the responses. RegistrationStatus provided the status details for the submitted registration. It echoes the original submission and provides status information about the request. RegistrationStatusType describes the structure of a registration status. Registration, at the very least echoes the submitted registration. It the request was to create a new registration and it was successful, an id must be supplied. StatusMessage provides that status for the registration request, and if necessary, any error or warning information. QueryRegistrationRequestType describes the structure of a registration query request. The type of query (data, reference metadata, or both) must be specified. It is possible to query for registrations for a particular provision agreement, data provider, or structure usage, or to query for all registrations in the registry. In addition the search can be refined by providing constraints in the form of explicit time periods, constraint regions, and key sets. When constraint regions and key sets are provided they will be effectively processed by first matching all data for the included keys and regions (all available data if there are none) and then removing any data matching the excluded keys or regions. QueryType defines the type of sets (data, metadata, or both) that are being queried for. All indicates that all registrations meeting the other criteria of the query should be returned. ProvisionAgreement provides a reference to a provision agreement in the registry, for which all registered sets meeting the other criteria of this query should be returned. The reference is provided as a URN and/or a complete set of reference fields. DataProvider provides a reference to a data provider in the registry, for which all registered sets meeting the other criteria of this query should be returned. The reference is provided as a URN and/or a complete set of reference fields. Dataflow provides a reference to a data flow in the registry, for which all registered sets meeting the other criteria of this query should be returned. The reference is provided as a URN and/or a complete set of reference fields. Metadataflow provides a reference to a metadata flow in the registry, for which all registered sets meeting the other criteria of this query should be returned. The reference is provided as a URN and/or a complete set of reference fields ReferencePeriod provides an inclusive start and end date for the data or metadata being sought. DataKeySet is used to provide a set of included or excluded keys which serves to refine the data being sought. CubeRegion is used to provide sets of include or excluded values for dimensions when querying for data. MetadataTargetRegion is used to provide sets of included or excluded values for identifier components when querying for metadata. The returnConstraints attribute determines whether information about the constraints on the data or metadata sets returned should also be sent the results. QueryRegistrationResponseType describes the structure of a registration query response. It provides a status for the request, and if successful, the resulting data and/or metadata results. StatusMessage provides that status for the registration query request, and if necessary, any error or warning information. QueryResult contains a result for a successful registration query. It can occur multiple times, for each registration the meets the conditions specified in the query. QueryResultType describes the structure of a query result for a single data source. Either a data result or metadata result is detailed, depending on the data source. The timeSeriesMatch attribute is true when the result is an exact match with the key found in the registry - that is, when the registered data source provides a matching key. It is set to false when the data source is registered with cube-region constraints, or in any other circumstance when it cannot be established that the sought-for keys have been exactly matched. This is always true when the resulting data source is the source of a metadata set. ResultType contains the details about a data or metadata source, through the complete registration information. In addition, a reference to the content constraints for the data source may be provided, if the query requested this information. Registration provides the details of a matching registration. In addition to the data source and provision agreement information, the id of the registration must also be provided. Constraint provides a reference to a data or metadata constraint in the registry for the resulting data source (or possibly constraints base on the registration provision agreement, data provider, structure usage, or structure). The reference is provided for by a URN and/or a complete set of reference fields. QueryType provides an enumeration of values which specify the objects in the result-set for a registry query. Only references data sets should be returned. Only references to metadata sets should be returned. References to both data sets and metadata sets should be returned.
