9 -The [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Technical Standards Version 1.0 established an information model which described aggregated statistical [[data sets>>doc:sdmx:Glossary.Data set.WebHome]] and the [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] needed to exchange them in a standard fashion. This drew on the earlier example of the GESMES/TS standard. Based on the [[SDMX information model>>doc:sdmx:Glossary.SDMX Information Model.WebHome]], several formats were developed: XML formats for exchange of [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]], [[data sets>>doc:sdmx:Glossary.Data set.WebHome]], and queries for these ([[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]]), and EDIFACT formats for the [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] and [[data sets>>doc:sdmx:Glossary.Data set.WebHome]] ([[SDMX-EDI>>doc:sdmx:Glossary.SDMX-EDI.WebHome]]). These standards supported a number of exchange patterns, characterized as "bilateral", "gateway", and "data-sharing" models, as described in the Framework document in the Version 1.0 standards package.

11 11  Versions 2.0 and 2.1 build on this foundation to provide a higher degree of support for all of these models, with an emphasis on data sharing in the form of a set of standard registry services interfaces. It has also expanded to include support for new types of metadata exchange and reporting, with a focus on "[[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]]" concerned with quality, methodology, and other issues. Further, the ability to provide metadata about the relationships between [[data sets>>doc:sdmx:Glossary.Data set.WebHome]] and structures has been expanded, providing more support for data cubes. Finally, experience has shown that some minor additions to the existing [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] and [[dataset>>doc:sdmx:Glossary.Data set.WebHome]] structures will allow [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] to support more different types of statistical information.

13 -The scope of the Version 2.1 [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Technical Standards is thus much broader, and is accompanied by a larger set of message types in the [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] formats. While the XML formats described here have grown in number and scope, the EDI formats remain relatively unchanged.
