7	7	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, where format is either generic or structured (i.e. the structure specific formats). This also applies to the message names as well, where the names follow the pattern of FormatData (e.g. StructuredData and GenericMetadata).
8	8
9		-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 structured data combined the principles of the previous (% style="color:#e74c3c" %)versions(%%) compact and cross sectional formats into one more generalised format.

11		-The major shift from the previous version is now that 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 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.

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>>doc:sdmx:Glossary.Measure.WebHome]] to be expressed when the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the [[measure>>doc:sdmx:Glossary.Measure.WebHome]] [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] defined in the data structured. The key differences from the previous (% style="color:#e74c3c" %)versions(%%) is that this all is possible in a single [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] specific format, as well as being possible in the generic format as well. The goal was to make the structures as homogenous as possible.

13		-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.

15		-Finally, in order to allow for systems which wish to not process the new more flexible data format, time series only variations of both the generic and structured data sets exist. It is important to note that these structures are derived via restriction from the more generalised format. This means that a data set in the general format with the time dimension at the observation level will have exactly the same content as a time series only data set. The result of this is that there is no additional burden for processing the time series specific format it a system can process the more generalised format. These time series only data sets allow for time series only data messages to exist. These messages make it simple for system which, in the previous version of the standard, only used the time series formats to continue to do so.

17		-These same principles have been applied to the reference data messages as well. In the previous version of the standard there were major differences between the generic and metadata structure-specific formats; some of the differences caused some metadata sets were incompatible between versions. In this version the structures of the generic and metadata structure specific formats have been harmonised to the point where they are nearly identical. Yet, the structured format still provides the strong validation against the metadata structure that is intended. And, as with the data, the base metadata structure specific format now imposes a stricter structure on the generated schemas, making the structure specific instance simpler to process in a generic manner.

38		-**DataSetType: **DataSetType defines the structure of the generic data set. Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The organisation used is dependent on the structure specification in the header of the data message (which is referenced via the structureRef attribute). The structure specification states which data occurs at the observation level. If this dimension is "AllDimensions" then the data set 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). 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.

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.

For example, a data structure defines a dimension with a coded representation. A data flow might have a constraint associated with it which further restricts the values allowed from the referenced code list to a subset of the values allowed by the data structure definition. A provision agreement that is based on the dataflow might also have a constraint, which further restricts the subset of the codelist from the dataflow. Therefore, the allowed content becomes stricter lower in the hierarchy. Data that is given a scope of one value is stated to be valid at that level and all levels below it. Therefore, this scope serves to state that data that is meant to be structured simply against the data structure definition is not meant to be validated against the a dataflow, where constraints might be applied.

924	924	It is assumed that in order to use this guide, the reader is familiar with schema terminology. However, for convenience the following is list of the terminology used here:
925	925
926	926	**Schema:** Refers to the format specific schema in general, and in particular the root xs:schema element of that schema file.
927	927
928		-**Global Element:** Refers to an element definition at the top level of the schema (i.e. an xs:element element in the root xs:schema element). It will define a name and type (name and type attributes) and possibly a substitution group (substitutionGroup attribute).
	920	+**Global Element:** Refers to an element definition at the top (% style="color:#e74c3c" %)level(%%) of the schema (i.e. an xs:element element in the root xs:schema element).

929	929
930		-**Local Element:** Refers to an element definition within a complex type (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). A local element must define a name and type (name and type attributes) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
	922	+**Local Element:** Refers to an element definition within a complex type (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). A local element must define a name and type (name and type [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
931	931
932	932	**Qualified/Unqualified Element:** A qualified element is an element that must be referred to by the namespace in which it was defined. An unqualified element does not have a namespace associated with it. The structure specific schemas make use of unqualified elements to that the structure specific schemas can restrict the base content to meet the specific needs of the structure, while maintaining as much of the original document structure as possible.
933	933
934		-**Element Reference:** Refers to an element definition within a complex type that is a reference to a global element (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). An element reference must reference a global element (via its ref attribute) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
	926	+**Element Reference:** Refers to an element definition within a complex type that is a reference to a global element (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element).

935	935
936		-**Complex Type:** Refers to a complex type definition. In this context, all complex type definitions occur at the top level of the schema (i.e. an xs:complexType element in the root xs:schema element). A complex type must define a name (name attribute) and may be made abstract (via the abstract attribute’s boolean value).
	928	+**Complex Type:** Refers to a complex type definition. In this context, all complex type definitions occur at the top (% style="color:#e74c3c" %)level(%%) of the schema (i.e. an xs:complexType element in the root xs:schema element).

937	937
938		-**Simple Type:** Refers to a simple type definition. In this context, all simple type definitions occur at the top level of the schema (i.e. an xs:simpleType element in the root xs:schema element). In this context, a simple type will always be defined via a restriction (an xs:restriction element in the xs:simpleType element). The restriction will reference a base type.
	930	+**Simple Type:** Refers to a simple type definition.

In this context, a simple type will always be defined via a restriction (an xs:restriction element in the xs:simpleType element). The restriction will reference a base type.
939	939
940	940	**Anonymous Type:** A complex or simple type definition which occurs within an element definition. The method is sometimes referred to a the "Russian-doll" technique as it creates nested constructs. Anonymous types are not given names and cannot be abstract. The can however, be derived from other types.
941	941
942	942	**Content Group:** A group which defines a content model for reuse. This is contained in the xs:group element, and is defined at the root of the schema. It allows for a common sequence or choice of elements to be reused across multiple types without having to redefine the sequence or choice in each type.
943	943
944		-**Uniqueness Constraint:** A uniqueness constraint is defined within an element and is used to force descendent elements to be unique based on some criteria of it fields (elements or attributes). This is defined in an <xs:unique> element, and has content of an <xs:selector> and multiple <xs:field> elements. The selector designates the descendants that must be unique (with an xpath attribute) and the field specifies which property of the selected element must be unique (also with an xpath attribute)

945	945
946		-**Extension:** Refers to the definition of a complex type that is an extension of another complex type. The extension will always make a reference to a base. In the schema, this is defined within the xs:complexType element as a child xs:complexContent element containing an xs:extension element (with a base attribute).
	938	+**Extension:** Refers to the definition of a complex type that is an extension of another complex type. The extension will always make a reference to a base.

949	949
950		-**Sequence:** Refers to a sequence of elements that may be defined as the root of a complex type content model, or as part of the content of a choice or another sequence. This is defined as an xs:sequence element. The sequence may specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
	942	+**Sequence:** Refers to a sequence of elements that may be defined as the root of a complex type content model, or as part of the content of a choice or another sequence.

953	953
954		-**Facet:** Refers to a single detail of a simple type restriction. This is represented by elements such as xs:minInclusive, xs:totalDigits, xs:minLength, and is contained in the xs:restriction element of a simple type definition. The value of the facet is contained in a value attribute of the particular element.

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.

1353		-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.
