78 -The [[SDMX Technical Specifications>>doc:sdmx:Glossary.SDMX Technical Specification.WebHome]] are now in (% style="color:#e74c3c" %)version(%%) 2.1, but both (% style="color:#e74c3c" %)version(%%) 1.0 and (% style="color:#e74c3c" %)version(%%) 2.0 were implemented. The 1.0 (% style="color:#e74c3c" %)version(%%) of the specifications have relatively limited coverage – a model for data formats and their structures, along with XML and UN/EDIFACT formats for exchanging these. The UN/EDIFACT format was backwardcompatible with GESMES/TS; the XML formats were new. There was also some support provided for [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]-based Web services: an XML query document, and a set of guidelines about the use of other related Web-services standards (SOAP and WSDL).

80 -The 2.0 (% style="color:#e74c3c" %)version(%%) of the technical specifications had a greatly-expanded scope. The model was extended to include “[[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]]” as a way of structuring and formatting metadata related to data quality frameworks, methodological metadata, and other types of “footnote” metadata. Thus, XML formats for [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]] were added. Further, a set of standard interfaces in XML for interactions with a [[SDMX Registry>>doc:sdmx:Glossary.SDMX Registry.WebHome]] were added, for cataloguing the location of data and [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]] across the Internet or within an organization, and for maintaining and retrieving structural metadata.

82 -In (% style="color:#e74c3c" %)version(%%) 2.1, many features of 2.0 have been improved, and the Web-services recommendations have been expanded to include a RESTful interface, standard functions, and error messages. Now, it is possible to develop generically interoperable applications based on the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] standards. Further, the various XML data formats have been simplified based on implementation experience with (% style="color:#e74c3c" %)version(%%) 2.0.

143 143  Looking forward, [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] is increasingly coming into use: at the most recent [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Global conference held in Washington DC in May 2011, Google showed some interest in [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] as a source of data for its Data Explorer; there is now an interest in setting up a [[global registry>>doc:sdmx:Glossary.Global registry.WebHome]] so that all [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] data and metadata sources can be easily found. Further, we see the strong possibility that the world of corporate statistics may realize the utility of having a strong standards basis around the vast amounts of data collected today to support business intelligence applications.
