1. Introduction

The registry schemas have been updated to reflect the various changes in the standard and to introduce new constructs for managing subscriptions. In addtion, the constructs that had existed for querying structural metadata have been removed as this is now handled by the query messages.

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 set registration. A data source must be supplied here if not already provided in the provision agreement. The data set or metadata set must be associated with a provision agreement, a metadata flow, or a dataflow definition. If possible, the provision agreement should be specified. Only in cases where this is not possible should the dataflow or metadata flow be used.

SubmitRegistrationsResponseType: SubmitRegistrationsResponseType describes the structure of a registration response. For each submitted registration in the request, a registration status is provided.

QueryRegistrationRequestType: 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.

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.

Content:
(StructuralRepositoryEvents | DataRegistrationEvents | MetadataRegistrationEvents)[1..3]

Element Documentation:

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.
