121 +Several of the changes are ‘breaking’ meaning that, in specific cases, the version 3.0 specification is not backwardly compatible with earlier versions of the Standard.
122 122  
123 123  The principle breaking changes are:
124 124  
125 125  * REST API – The REST API is not backwardly compatible due to modifications to the URLs and query parameters resulting in breaking changes in four of the five main resources.
126 -* SOAP API – Deprecation of the SOAP API means that existing systems designed to use SOAP will not work with (% style="color:#e74c3c" %)version(%%) 3.0 registries.
127 -* [[SDMX-ML>>doc:sdmx:Glossary 2\.1.SDMX-ML.WebHome]] – [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 2.1 and earlier structure, data and metadata XML messages are not valid in (% style="color:#e74c3c" %)version(%%) 3.0. Specifically: legacy data messages including Generic, Compact and Utility are no longer supported. The remaining Structure Specific data message has been changed to support new features such as reporting of [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] as part of the [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]], Structure messages have a number of breaking changes, principally modification to the information model, removal of the agency-(% style="color:#e74c3c" %)version(%%)-id option for referencing [[artefacts>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] and changes to the way the structures are organised into ‘collections’ within the message.
128 -* [[SDMX-JSON>>doc:sdmx:Glossary 2\.1.SDMX-JSON.WebHome]] – [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 2.1 structure, data and metadata JSON messages are not valid in (% style="color:#e74c3c" %)version(%%) 3.0. The data message has been changed to support the improved REST data queries, in particular the ability to retrieve in one operation data from multiple [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] with potentially different [[Data Structure Definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. Breaking changes similar to those for the [[SDMX-ML>>doc:sdmx:Glossary 2\.1.SDMX-ML.WebHome]] transmission format have been made to the structure message.
129 -* [[SDMX-CSV>>doc:sdmx:Glossary 2\.1.SDMX-CSV.WebHome]] - The CSV data and [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] messages are not backwardly compatible with those under (% style="color:#e74c3c" %)version(%%) 2.1 due to changes to the structure of the messages needed to support new features such as the improved REST API data queries.
130 -* [[SDMX-EDI>>doc:sdmx:Glossary 2\.1.SDMX-EDI.WebHome]] – Deprecation of the EDI transmission format means that existing systems designed to send or receive structures or data in EDI will not work with (% style="color:#e74c3c" %)version(%%) 3.0 registries.
131 -* Information Model – Several structures have been changed in the (% style="color:#e74c3c" %)version(%%) 3.0 model and three removed. For these reasons the (% style="color:#e74c3c" %)version(%%) 3.0 model is not directly compatible with (% style="color:#e74c3c" %)version(%%) 2.1 or earlier, although conversion of specific [[artefacts>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] is possible under some circumstances. Loss of information during the conversion process however means that in cases like structure mapping, the conversion is not reversible i.e. it is not possible to recreate the 2.1 structure once it has been converted to the 3.0 model.
126 +* SOAP API – Deprecation of the SOAP API means that existing systems designed to use SOAP will not work with version 3.0 registries.
127 +* [[SDMX-ML>>doc:sdmx:Glossary 2\.1.SDMX-ML.WebHome]] – [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 2.1 and earlier structure, data and metadata XML messages are not valid in version 3.0.

128 +* [[SDMX-JSON>>doc:sdmx:Glossary 2\.1.SDMX-JSON.WebHome]] – [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 2.1 structure, data and metadata JSON messages are not valid in version 3.0. The data message has been changed to support the improved REST data queries, in particular the ability to retrieve in one operation data from multiple [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] with potentially different [[Data Structure Definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]].
