9 -The [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Technical Standards (% style="color:#e74c3c" %)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 (% style="color:#e74c3c" %)Version(%%) 1.0 standards package.

11 -(% style="color:#e74c3c" %)Versions(%%) 2.0 and 2.1 built 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. Support for new types of metadata exchange and reporting were added, 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 was expanded, providing more support for data cubes. Overall, the scope of the (% style="color:#e74c3c" %)Version(%%) 2.1 [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Technical Standards was much broader, and included a larger set of message types in the [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] formats.

13 -For (% style="color:#e74c3c" %)Version(%%) 3.0, the [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] specification has been rationalised and tightened while maintaining the fundamentals and principles established in 2.1. The documents for describing [[structural metadata>>doc:sdmx:Glossary.Structural metadata.WebHome]] remain the same except where there have been changes to the information model either to enhance existing structures, add new ones, or remove those deprecated such as the Structure Set.

15 -The deprecation of the SOAP web services specification in (% style="color:#e74c3c" %)Version(%%) 3.0 has resulted in the removal of all [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] Query documents. Standardisation on the REST API and HTTP GET for registry structure queries means separate 'query request' documents are no longer required.

17 -The opportunity has also been taken to rationalise the plethora of alternative data documents accumulated from (% style="color:#e74c3c" %)Versions(%%) 1.0, 2.0 and 2.1. All, including Generic, Utility, Compact and Cross-Sectional have been deprecated except for Structure Specific Data which becomes the sole standard XML format for data updates, revisions and bilateral exchanges in (% style="color:#e74c3c" %)Version(%%) 3.0.
