  The various data messages which existed in the standard have been harmonised into two general formats; generic and structured data. The generic data is much like it has been previously, only slightly modified to conform with the harmonised view on data. The structured data combined the principles of the previous versions compact and cross sectional formats into one more generalised format.
--The major shift from the previous version is now that all data can be exchanged as either an un-grouped collection oData structure and metadata structure-specific schemas are each based on one single core construct found in their respective structure-specific namespaces;f observations, each specifying a full key or it can be exchanged as data grouped into series with any single dimension placed at the observation level. This in effect, combined the abilities of the time series and cross sectional formats in the a single data format. This format also allows for multiple measure to be expressed when the observation dimension is the measure dimension defined in the data structured. The key differences from the previous versions is that this all is possible in a single data structure definition specific format, as well as being possible in the generic format as well. The goal was to make the structures as homogenous as possible.

The key differences from the previous versions is that this all is possible in a single data structure definition specific format, as well as being possible in the generic format as well. The goal was to make the structures as homogenous as possible.
  Another shift from the previous version in the manner in which the base data structure specific format is defined. In previous versions there was not structure defined, so one had to understand all of the requirements and read the specification in order to understand what could be expected in any structure specific format. In this version, that issue has been addressed. The base structures now impose a strict format on the data structure specific schemas. This is achieved much like the referencing structure in the common namespace through the use of unqualified elements. By the elements not existing in a namespace, the structure specific schemas can place the necessary restrictions of them while still being forced to adhere to prescribed structure. This means that not only are the structures able to perform the validation that is required, but that the messages will be much simpler to process as the format will always use the same element names.

  **GroupType: **GroupType defines a structure which is used to communicate attribute values for a group defined in a data structure definition. The group can consist of either a subset of the dimensions defined by the data structure definition, or an association to an attachment constraint, which in turn defines key sets to which attributes can be attached. In the case that the group is based on an attachment constraint, only the identification of group is provided. It is expected that a system which is processing this will relate that identifier to the key sets defined in the constraint and apply the values provided for the attributes appropriately.

  **//DataSetType//: **DataSetType is the abstract type which defines the base structure for any data structure definition specific data set. A derived data set type will be created that is specific to a data structure definition and the details of the organisation of the data (i.e. which dimension is the observation dimension and whether explicit measures should be used). Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The derived data set type will restrict this choice to be either grouped or un-grouped observations. If this dimension is "AllDimensions" then the derived data set type must consist of a collection of un-grouped observations; otherwise the data set will contain a collection of series with the observations in the series disambiguated by the specified dimension at the observation level. This data set is capable of containing data (observed values) and/or documentation (attribute values) and can be used for incremental updates 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 specific data will have a consistent structure. The group, series, and observation elements are unqualified, meaning that they are not qualified with a namespace in an instance. This means that in the derived data set 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 specific schema. The data set can contain values for attributes which do not have an attribute relationship with any data structure definition components. These attribute values will exist in XML attributes in this element based on this type (DataSet). This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived data set type will refine this structure so that the attributes are explicit. The XML attributes will be given a name based on the attribute's identifier. These XML attributes will be unqualified (meaning they do not have a namespace associated with them). To allow for generic processing, it is required that the only unqualified XML attributes in the derived data set type (outside of the standard data set attributes) be for attributes declared in the data structure definition. If additional attributes are required, these should be qualified with a namespace so that a generic application can easily distinguish them as not being meant to represent a data structure definition attribute.

  **//GroupType//: **GroupType is the abstract type which defines a structure which is used to communicate attribute values for a group defined in a data structure definition. The group can consist of either a subset of the dimensions defined by the data structure definition, or an association to an attachment constraint, which in turn defines key sets to which attributes can be attached. In the case that the group is based on an attachment constraint, only the identification of group is provided. It is expected that a system which is processing this will relate that identifier to the key sets defined in the constraint and apply the values provided for the attributes appropriately. Data structure definition schemas will drive types based on this for each group defined in the data structure definition. Both the dimension values which make up the key (if applicable) and the attribute values associated with the group will be represented with XML attributes. This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived group type will refine this structure so that the attributes are explicit. The XML attributes will be given a name based on the attribute's identifier. These XML attributes will be unqualified (meaning they do not have a namespace associated with them). The dimension XML attributes will be required while the attribute XML attributes will be optional. To allow for generic processing, it is required that the only unqualified XML attributes in the derived group type be for the group dimensions and attributes declared in the data structure definition. If additional attributes are required, these should be qualified with a namespace so that a generic application can easily distinguish them as not being meant to represent a data structure definition dimension or attribute.

++For any given representation, there exist rules for determining the simple or primitive type which should be used to validate the value. There are no specific requirements to how a simple type is named or if it is referenced or used as an anonymous type. This section simply serves to state the requirements of the type for a component based on its [[determined representation>>path:#_Representation_Determination:]].
  For example, a dimension may inherit its representation for a concept, and the data type of a representation data type may be a String. The simplest solution would be to use the xs:string primitive type. However, an implementer may have chosen to generate simple types for all concepts to avoid having to look up the concept core representation for very component. In this case, the type may be given a name based on the concept and be a simple derivation from the xs:string type that places no further restrictions. The result would be that the type that is actually used for the dimension, although named after the concept, is effectively the required xs:string. These rules are meant to allow such flexibility in how types are created. The only requirement is that the type meet the requirements stated here.

  A representation which defines an enumeration will result in a simple type that is a restriction of the common:IDType. The simple type will define enumerations for each item in the item scheme. The value for these enumerations will be identifier of the item. If desired, the names of the item may be placed in the documentation of the enumeration, but this is not required. Example:

  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.
  For example, an organisation my create predefined types for all of codelists and concept schemes which their structures utilize. These could be contained in a common schema with any namespace deemed appropriate. This would allow the structure specific schemas generation process to recognize the reused components and not be concerned with regenerating types. The logical flow for setting the representation of a component might be as follows:
--> Does the component define a local type?
--> Yes: Is that type enumerated?
--> Yes: Type is the qualified type name for the item scheme
--> No: Generate simple type for text format
--> No: Type is the qualified name for the concept from which the component takes its semantic.

  Separate schemas will be created for the data structure depending on which dimension occurs at the observation level, and whether explicit measures are used in the case that the observation dimension is the measure dimension. The recommended target namespace of the data structured specific schema is: [Data Structure URN]:ObsLevelDim:[Observation Dimensions](:explicit)?. Note that the explicit trailer is only used when the measure dimension is used at the observation level and the explicit measure concepts are to be used.
  The rules for generating the data structure specific-schema are broken into sections based on the level within the structure (i.e. data set, group, series, observation). Each section will state the rules for each variation of the structure specific format.

If the dimension at the observation level is the time dimension (TIME_PERIOD) the base type of the restriction is dsd:TimeSeriesDataSetType. Otherwise, the base type of the restriction is dsd:DataSetType. The complex type content model will be as follows:

--* a. An element reference to common:Annotations, with a minimum occurrence of 0
--* b. A local element named DataProvider with the type common:DataProviderReferenceType, a form of unqualified and a minimum occurrence of 0

  An identifiable object target is meant to reference an SDMX identifiable object. In the metadata structure specific schema, the complex type which defines the reference is restricted according to the local representation and object type of the identifiable object target. If the identifiable object target does not provide an enumeration in its local representation, then the complex type for the target object is the specific reference type from the common namespace, based on the object type defined by the target object. For example, if the object type is DataProivder, the type will be common:DataProviderReferenceType. The general rule for the name of this type is common:[object type]ReferenceType.
  If the target object defines an enumeration in its local representation, then the declared object type must be for the items contained the enumeration's referenced item scheme. If this is not true, the reference type as defined above is the type for the target object.

--~1. A sequence consisting of:
--* a. An element reference to common:Annotations, with a minimum occurrence of 0
--* b. A local element named Target with the type previously defined as [report structure identifier].TargetType, and a form of unqualified. This element must define a uniqueness constraint with a recommended name of [report structure identifier].Target.ReferenceValue.Unique. This uniqueness constraint must contain:
--** i. A selector with an xpath of "*"
--** ii. A field with an xpath of "@id"
--* c. A local element named AttributeSet with a form of unqualified and a type as defined according to the rules defined in Attribute Set Complex Type Creation
--2. An attribute named id with the type previously defined as Report.ID, a use of optional, and a fixed value of [report structure identifier]
++1. A sequence consisting of:

++1111. Attribute Set Complex Type Creation
  An attribute set is created for a report structure or a metadata attribute which contains child metadata attributes. This type is a complex type with a recommend name of [report structure identifier].[nested metadata attribute identifier].AttributeSet, where the metadata attribute section only applies to attribute sets created for metadata attributes and is assumed to consist of the full hierarchy of the metadata attribute's definition. This complex type must consists of:
--~1. A sequence consisting of:
--* a. A local element for each metadata attribute defined as a direct child of the object for which the attribute set is being created. The recommended name of this element is [metadata attribute identifier] and it has a form of unqualified. If the metadata attribute defines a minOccurs and maxOccurs, these values are translated to this element. The type of this element is the type previously created as [report structure identifier].[nested metadata attribute identifier].

  Both the generic and the structure-specific data messages allow for incremental updating of data. This purpose is noted in the action for the data set, which is either inherited from the header of the data message or explicitly stated at the data set level.
++
  A dataset with an action of Append is assumed to be an incremental update. This means that one the information provided explicitly in the message should be altered. Any data attribute or observation value that is to be changed must be provided. However, the absence of an observation value or a data attribute at any level does not imply deletion; instead it is simply implied that the value is to remain unchanged. Therefore, it is valid and acceptable to send a data message with an action of Append which contains only a Series elements with attribute values. In this case, the values for the attributes will be updated. Note that it is not permissible to update data attributes using partial keys (outside of those associated with defined groups). In order to update an attribute, a full key must always be provided even if the message format does not require this.

--== 4.2 Deletes ==
--
  Both the generic and the structure-specific data messages allow for incremental deletion of data. This purpose is noted in the action for the data set, which is either inherited from the header of the data message or explicitly stated at the data set level.
++
  A dataset with an action of Delete is assumed to be an incremental deletion. The deletion is assumed to take place of the lowest level of detail provided in the message. For example, if a delete message is sent with only a data set element, the entire data set will be deleted. On the other hand, if that data set contains a data attribute, only that data attribute value will be deleted. This same dynamic continues through the data set hierarchy. A data set containing only a series with no data attributes or observations will result in that entire series (all observations and data attributes) being deleted. If the series contains data attributes, only the supplied data attributes for that series will be deleted. Finally, if a series contains observations, then only the specified observations will be deleted. If an entire observation is to be deleted (value and data attributes), only the observation dimension should be provided. If only the observation value or particular data attributes are to be deleted, then these should be specified for the observation. Note that a group can only be used to delete the data attributes associated with it. Although the format might not require it, a full key must be provided to delete a series or observation. It is not permissible to wild card a key in order to delete more than one series or observation. Finally, to delete a data attribute or observation value it is recommended that the value to be deleted be supplied; however, it is only required that any valid value be provided.
