47		-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:

	50	+* standardised XML schemas derived from the model ([[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]-ML)
51	51	* the use of web-services technology (XML, XSD, WSDL, WADL)
52	52
53		-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.

55		-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.

59		-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.
