--The business vision for SDMX envisages the promotion of a “data sharing” model to facilitate low-cost, high-quality statistical data and metadata exchange. Data sharing 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:

Data sharing 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 timeseries and cross-sectional data, structural metadata, and reference metadata (SDMX-IM)
--* standardised XML schemas derived from the model (SDMX-ML)

++* standardised XML schemas derived from the model ([[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]-ML)
  * the use of web-services technology (XML, XSD, WSDL, WADL)
--Such an architecture needs to be well organised, and the SDMX Registry/Repository (SDMX-RR) is tasked with providing structure, organisation, and maintenance and query interfaces for most of the SDMX components required to support the datasharing vision.

--However, it is important to emphasis that the SDMX-RR provides support for the submission and retrieval of all SDMX structural metadata 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.

--As organisations migrate to SDMX enabled systems, many XML (and conventional) artefacts will be produced (e.g. Data Structure, Metadata Structure, Code List and Concept definitions (often collectively called structural metadata), XML schemas generated from data and metadata structure definitions, XSLT style-sheets for transformation and display of data and metadata, terminology references, etc.). The SDMX model supports interoperability, and it is important to be able to discover and share these artefacts between parties in a controlled and organized way.

  === 6.2.2 Universal Resource Name (URN) ===
  ==== 6.2.2.1 Introduction ====
--To provide interoperability between SDMX Registry/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 objects. Most of these unique identifiers are composite (containing maintenance agency, 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 in the SDMX-RR APIs. In other words, the URN for any Identifiable Artefact is constructed from its component identifiers (agency, Id, version etc.).

--The SDMX Registry must have the ability to support agencies in their role of defining and disseminating structural metadata artefacts. These artefacts include data structure definitions, code lists, concepts etc. and are fully defined in the SDMX-IM. An authenticated agency may submit valid structural metadata definitions which must be stored in the registry. Note that the term “structural metadata” refers as a general term to all structural components (Data structure Definitions, Metadata Structure Definitions, Code lists, Concept Schemes, etc.)

An authenticated agency may submit valid [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] definitions which must be stored in the registry. Note that the term “[[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]]” refers as a general term to all structural [[components>>doc:sdmx:Glossary.Component.WebHome]] ([[Data structure Definitions>>doc:sdmx:Glossary.Data structure definition.WebHome]], [[Metadata Structure Definitions>>doc:sdmx:Glossary.Metadata structure definition.WebHome]], [[Code lists>>doc:sdmx:Glossary.Code list.WebHome]], [[Concept Schemes>>doc:sdmx:Glossary.Concept scheme.WebHome]], etc.)
--At a minimum, structural metadata definitions may be submitted to and queried from the registry via an HTTP/HTTPS POST in the form of one of the SDMX-ML registry messages for structural metadata and the SDMX Query message for structure queries. The use of SOAP is also recommended, as described in the SDMX Web Services Guidelines. The message may contain all structural metadata items for the whole registry, structural metadata items for one maintenance agency, or individual structural metadata items.

--The level of granularity for the maintenance of SDMX Structural Metadata objects in the registry is the Maintainable Artefact. In other words, any function such as add, modify, delete is at the level of the Maintainable Artefact. For instance, if a Code is added to a Code List, or the Name of a Code is changed, the Registry must replace the existing Code List with the submitted Code List of the same Maintenance Agency, Code List, Id and Version.

--Data provisioning defines a framework in which the provision of different types of statistical data and metadata by various data providers can be specified and controlled. This framework is the basis on which the existence of data can be made known to the SDMX-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 level agreements, or other provisioning agreements in those scenarios that are based on legal directives. Additionally, quality and timeliness metadata can be supported by this framework which makes it practical to implement information supply chain monitoring.

  == 7.3 Data and Metadata Constraints ==
  === 7.3.1 Data and Metadata Constraints: Basic Concepts ===
--Constraints are, effectively, lists of the valid or actual content of data and metadata. Constraints can be used to specify a sub set of the theoretical content of data set or metadata set which can be derived from the specification of the DSD or MSD. A Constraint can comprise a list of keys or a list of content (usually code values) of a specific component such as a dimension or attribute.

[[Constraints>>doc:sdmx:Glossary.Constraint.WebHome]] can be used to specify a sub set of the theoretical content of [[data set>>doc:sdmx:Glossary.Data set.WebHome]] or [[metadata set>>doc:sdmx:Glossary.Metadata set.WebHome]] which can be derived from the specification of the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] or [[MSD>>doc:sdmx:Glossary.Metadata structure definition.WebHome]].

--Constraints comprise the specification of subsets of key or target values or attribute values that are contained in a Datasource, or is to be provided for a Dataflow or Metadataflow Definition, or directly attached to a Data Structure Definition or Metadata Structure Definition. This is important metadata because, for example, the full range of possibilities which is implied by the Data Structure Definition (e.g. the complete set of valid keys is the Cartesian product of all the values in the code lists for each of the Dimensions) is often more than is actually present in any specific Datasource, or more than is intended to be supplied according to a specific Dataflow Definition.

--Often a Data Provider will not be able to provide data for all key combinations, either because the combination itself is not meaningful, or simply because the provider does not have the data for that combination. In this case the Data Provider could constrain the Datasource (at the level of the Provision Agreement or the Data Provider) by supplying metadata that defines the key combinations or cube regions that are available. This is done by means of a Constraint. The Content Constraint is also used to define a code list sub set which is used to populate a Partial Code List.

--Furthermore, it is often useful to define subsets or views of the Data Structure Definition which restrict values in some code lists, especially where many such subsets restrict the same Data Structure Definition. Such a view is called a Dataflow Definition, and there can be one or more defined for any Data Structure Definition.
