  The first change in the data and metadata message is one of terminology. In order to foster consistency in the standard, the names and namespaces of the data and metadata message have been changed. The namespaces now have a uniform format of /data/format and /metadata/format. This also applies to the message names as well, where the names follow the pattern of FormatData (e.g. StructuredData and GenericMetadata).
--For data messages, since version 3.0 only the (data-)structure-specific format is maintained, the generic format being deprecated. The structure-specific data message combines the principles of the former compact and cross-sectional formats into one more generalised format. All data can be exchanged as either an un-grouped collection of observations, each specifying a full key, or it can be exchanged as data grouped into series with any single [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] placed at the observation level.

  A base schema now imposes a strict format for the generated structure-specific schemas. This not only allows performing the required validations, but the messages will also be much simpler to process as the format will always use the same element names.

--//**DataSetType:**// DataSetType is the abstract type which defines the base structure for any [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] specific [[data set>>doc:sdmx:Glossary.Data set.WebHome]]. A derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type will be created that is specific to a [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] and the details of the organisation of the data (i.e. which [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]]). Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type will restrict this choice to be either grouped or un-grouped observations. If this [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is "AllDimensions" then the derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type must consist of a collection of un-grouped observations; otherwise, the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] will contain a collection of series with the observations in the series disambiguated by the specified [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] at the observation level. This [[data set>>doc:sdmx:Glossary.Data set.WebHome]] is capable of containing data (observed values) and/or documentation (data and metadata [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] values) and can be used for [[incremental updates>>doc:sdmx:Glossary.Incremental update.WebHome]] and deletions (i.e. only the relevant updates or deletes are exchanged). It is assumed that each series or un-grouped observation will be distinct in its purpose. For example, if series contains both data and documentation, it assumed that each series will have a unique key. If the series contains only data or only documentation, then it is possible that another series with the same key might exist, but with not with the same purpose (i.e. to provide data or documentation) as the first series. This base type is designed such that derived types can be processed in a generic manner; it assures that [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] specific data will have a consistent structure. The group, series, obs, and atts elements are unqualified, meaning that they are not qualified with a namespace in an instance. This means that in the derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] types, the elements will always be the same, regardless of the target namespace of the schemas which defines these derived types. This allows for consistent processing of the structure without regard to what the namespace might be for the [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] specific schema.

  It is possible that organisations that manage a large number of structure-specific schemas my wish to take advantage of the reuse of previously defined type in order to simply the structure-specific schema creation and lessen the number of schema elements which are created. The structure-specific formats are designed in such a way that this would be allowed without any adverse affects.
