--The business vision for [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] envisages the promotion of a “data sharing” model to facilitate low-cost, high-quality [[statistical data and metadata exchange>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]].

[[Data sharing>>doc:sdmx:Glossary 2\.1.Data sharing.WebHome]] reduces the reporting burden of organisations by allowing them to publish data once and let their counterparties “pull” data and related metadata as required. The scenario is based on:
--* the availability of an abstract information model capable of supporting time series and cross-sectional data, [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]], and [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]] ([[SDMX-IM>>doc:sdmx:Glossary.SDMX Information Model.WebHome]])
--* standardised XML and JSON schemas for the [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] and [[SDMX-JSON>>doc:sdmx:Glossary.SDMX-JSON.WebHome]] formats derived from the model (XSD, JSON)

--However, it is important to emphasise that the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]-RR provides support for the submission and retrieval of all [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] and provisioning metadata. Therefore, the Registry not only supports the data-sharing scenario, but this metadata is also vital in order to provide support for data and metadata reporting/collection, and dissemination scenarios.

  Whilst the introductory section contains some information on the role of the registry, it is assumed that the reader is familiar with the uses of a registry in providing shared metadata across a community of counterparties.
--Note that chapters 5 and 6 below contain normative rules regarding the Registry Interface and the identification of registry objects. Further, the minimum standard for access to the registry is via a REST interface (HTTP or HTTPS), as described in the appropriate sections. The [[notification>>doc:sdmx:Glossary.Notification.WebHome]] mechanism must support e-mail and HTTP/HTTPS protocols as described. Normative registry interfaces are specified in the [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] specification (Section 3 of the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Standard). All other sections of this document are informative.

--The following table defines the behaviour of the [[SDMX Registry>>doc:sdmx:Glossary.SDMX Registry.WebHome]] for the various Registry Interface messages. It should be noted, though, that as of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] 3.0, an extended versioning scheme newly including semantic versioning is foreseen for all [[Maintainable Artefacts>>doc:sdmx:Glossary.Maintainable artefact.WebHome]].

  === 6.2.2 Universal Resource Name (URN) ===
  ==== 6.2.2.1 Introduction ====
--To provide interoperability between [[SDMX Registry>>doc:sdmx:Glossary.SDMX Registry.WebHome]]/Repositories in a distributed network environment, it is important to have a scheme for uniquely identifying (and thus accessing) all first-class (Identifiable) [[SDMX-IM>>doc:sdmx:Glossary.SDMX Information Model.WebHome]] objects. Most of these unique identifiers are composite (containing [[maintenance agency>>doc:sdmx:Glossary.Maintenance agency.WebHome]], or parent object identifiers), and there is a need to be able to construct a unique reference as a single string. This is achieved by having a globally unique identifier called a universal resource name (URN) which is generated from the actual identification [[components>>doc:sdmx:Glossary.Component.WebHome]] in the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]-RR APIs. In other words, the URN for any [[Identifiable Artefact>>doc:sdmx:Glossary.Identifiable artefact.WebHome]] is constructed from its [[component>>doc:sdmx:Glossary.Component.WebHome]] identifiers (agency, id, (% style="color:#e74c3c" %)version(%%) etc.).

  ==== 6.2.2.2 URN Structure //__Case Rules for URN__// ====
  For the URN, all parts of the string are case sensitive. The generic structure of the URN is as follows:
--SDMXprefix.[[SDMX-IM>>doc:sdmx:Glossary.SDMX Information Model.WebHome]]-package-name.class-name=agencyid:maintainedobjectid(maintainedobject-(% style="color:#e74c3c" %)version(%%)).*containerobject-id.object-id

  ~* this can repeat and may not be present (see explanation below)
--Note that in the [[SDMX Information Model>>doc:sdmx:Glossary.SDMX Information Model.WebHome]] there are no concrete [[Versionable Artefacts>>doc:sdmx:Glossary.Versionable artefact.WebHome]] that are not a [[Maintainable Artefact>>doc:sdmx:Glossary.Maintainable artefact.WebHome]]. For this reason, the only (% style="color:#e74c3c" %)version(%%) information that is allowed is for the maintainable object.
++Note that in the [[SDMX Information Model>>doc:sdmx:Glossary 2\.1.SDMX Information Model.WebHome]] there are no concrete [[Versionable Artefacts>>doc:sdmx:Glossary 2\.1.Versionable artefact.WebHome]] that are not a [[Maintainable Artefact>>doc:sdmx:Glossary 2\.1.Maintainable artefact.WebHome]]. For this reason, the only (% style="color:#e74c3c" %)version(%%) information that is allowed is for the maintainable object.
--The [[Maintenance agency>>doc:sdmx:Glossary.Maintenance agency.WebHome]] identifier is separated from the [[maintainable artefact>>doc:sdmx:Glossary.Maintainable artefact.WebHome]] identifier by a colon ‘:’. All other identifiers in the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] URN syntax are separated by a period ‘.’. The (% style="color:#e74c3c" %)version(%%) information is encapsulated in parentheses ‘()’ and adheres to the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] versioning rules, as explained in [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Standards Section 6 “Technical Notes”, paragraph “4.3 Versioning.
++The [[Maintenance agency>>doc:sdmx:Glossary 2\.1.Maintenance agency.WebHome]] identifier is separated from the [[maintainable artefact>>doc:sdmx:Glossary 2\.1.Maintainable artefact.WebHome]] identifier by a colon ‘:’.

  ==== 6.2.2.3 Explanation of the generic structure ====
  In the explanation below the actual object that is the target of the URN is called the **actual object**.
--**SDMXPrefix**: urn:sdmx:org
++**SDMXPrefix**: urn:[[sdmx>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]]:org
--**SDMX-IM-package-name**: sdmx.infomodel.package=
++**[[SDMX-IM>>doc:sdmx:Glossary 2\.1.SDMX Information Model.WebHome]]-package-name**: [[sdmx>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]].infomodel.package=

++base [[codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] conceptscheme datastructure categoryscheme registry metadatastructure process structuremapping transformation
  **maintainable-object-id** is the identifier of the maintainable object. This will always be present as all identifiable objects are either a maintainable object or contained in a maintainable object.
--**maintainable-object-version** is the (% style="color:#e74c3c" %)version(%%), according to the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] versioning rules, of the maintainable object and is enclosed in parentheses ‘()’, which are always present.
++**maintainable-object-(% style="color:#e74c3c" %)version(%%)** is the (% style="color:#e74c3c" %)version(%%), according to the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] versioning rules, of the maintainable object and is enclosed in parentheses ‘()’, which are always present.
--**container-object-id** is the identifier of an intermediary object that contains the actual object which the URN is identifying. It is not mandatory as many actual objects do not have an intermediary container object. For instance, a [[Code>>doc:sdmx:Glossary.Code.WebHome]] is in a maintained object (Codelist) and has no intermediary container object, whereas a MetadataAttribute has an intermediary container object (MetadataAttributeDescriptor) and may have an intermediary container object, which is its parent MetadataAttribute. For this reason, the container object id may repeat, with each repetition identifying the object at the next-lower (% style="color:#e74c3c" %)level(%%) in its [[hierarchy>>doc:sdmx:Glossary.Hierarchy.WebHome]]. Note that if there is only a single containing object in the model then it is NOT included in the URN structure. This applies to AttributeDescriptor, DimensionDescriptor, and MeasureDescriptor where there can be only one such object and this object has a fixed id. Therefore, whilst each of these has a URN, the id of the AttributeDescriptor, DimensionDescriptor, and MeasureDescriptor is not included when the actual object is a DataAttribute or a [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]/ TimeDimension, or a Measure.
++**container-object-id** is the identifier of an intermediary object that contains the actual object which the URN is identifying. It is not mandatory as many actual objects do not have an intermediary container object. For instance, a [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] is in a maintained object ([[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]]) and has no intermediary container object, whereas a MetadataAttribute has an intermediary container object (MetadataAttributeDescriptor) and may have an intermediary container object, which is its parent MetadataAttribute. For this reason, the container object id may repeat, with each repetition identifying the object at the next-lower (% style="color:#e74c3c" %)level(%%) in its [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]]. Note that if there is only a single containing object in the model then it is NOT included in the URN structure.

Therefore, whilst each of these has a URN, the id of the AttributeDescriptor, DimensionDescriptor, and MeasureDescriptor is not included when the actual object is a DataAttribute or a [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]/ TimeDimension, or a [[Measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]].
--Note that although a [[Code>>doc:sdmx:Glossary.Code.WebHome]] can have a parent [[Code>>doc:sdmx:Glossary.Code.WebHome]] and a (% style="color:#e74c3c" %)Concept(%%) can have a parent (% style="color:#e74c3c" %)Concept(%%) these are maintained in a flat structure and therefore do not have a containerobject-id.
++Note that although a [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] can have a parent [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] and a (% style="color:#e74c3c" %)Concept(%%) can have a parent (% style="color:#e74c3c" %)Concept(%%) these are maintained in a flat structure and therefore do not have a containerobject-id.
  For example, the sequence is agency:DSDid((% style="color:#e74c3c" %)version(%%)).DimensionId and not agency:DSDid((% style="color:#e74c3c" %)version(%%)).DimensionDescriptorId.DimensionId.

  == 7.2 Data and Metadata Provisioning ==
  === 7.2.1 Provisioning Agreement: Basic concepts ===
--Data/Metadata provisioning defines a framework in which the provision of different types of statistical data and metadata by various data/metadata providers can be specified and controlled. This framework is the basis on which the existence of data can be made known to the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]-enabled community and hence the basis on which data can subsequently be discovered. Such a framework can be used to regulate the data content to facilitate the building of intelligent applications. It can also be used to facilitate the processing implied by service (% style="color:#e74c3c" %)level(%%) agreements, or other provisioning agreements in those scenarios that are based on legal directives. Additionally, quality and [[timeliness>>doc:sdmx:Glossary.Timeliness.WebHome]] metadata can be supported by this framework which makes it practical to implement information supply chain monitoring.

--Although the [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] directly supports the data-sharing “pull” model, it is also useful in “push” exchanges (bilateral and gateway scenarios), or in a dissemination environment. It should be noted, too, that in any exchange scenario, the registry functions as a repository of structural metadata.
