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. This also applies to the message names as well, where the names follow the pattern of FormatData (e.g. StructuredData and GenericMetadata).

9		-For data messages, since (% style="color:#e74c3c" %)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.

11	11	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.

69		-|Atts|*AttsType*|Atts contains a set of data or metadata attribute values with an attachment level of none (i.e. data set level) or reported against a partial set of dimension values.
70		-|Group|*GroupType*|Group contains a reference to a defined group in the data structure definition along with its key (if necessary) and values for the attributes which are associated with the group. An attribute is associated to a group by either an explicit group relationship or by a group attachment when the attribute has a relationship with a dimension which is a member of this group.
71		-|Series|*SeriesType*|Series contains a collection of observations that share a common key (set of dimension values). The key of a series is every dimension defined in the data structure definition, save the dimension at the observation level. In addition to the key and observations, the series contains values for data and metadata attributes which have a relationship with any dimension that is part of the series key, so long as the attribute does not specify an attachment group or also has a relationship with the dimension declared to be at the observation level.
72		-|Obs|*ObsType*|Obs is an un-grouped observation. This observation has a key which is a set of values for all dimensions declared in the data structure definition. In addition to the key, the value of the observation can be provided along with values for all data and metadata attributes which have an association with the observation or any dimension (so long as it does not specify a group attachment).
	69	+|Atts|//AttsType//|Atts contains a set of data or metadata attribute values with an attachment level of none (i.e. data set level) or reported against a partial set of dimension values.
	70	+|Group|//GroupType//|Group contains a reference to a defined group in the data structure definition along with its key (if necessary) and values for the attributes which are associated with the group. An attribute is associated to a group by either an explicit group relationship or by a group attachment when the attribute has a relationship with a dimension which is a member of this group.

	72	+|Obs|//ObsType//|Obs is an un-grouped observation. This observation has a key which is a set of values for all dimensions declared in the data structure definition. In addition to the key, the value of the observation can be provided along with values for all data and metadata attributes which have an association with the observation or any dimension (so long as it does not specify a group attachment).
73	73	|Metadata|MetadataSetType|Allows for attachment of reference metadata against to the data set.
74	74
75	75	//**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 data or metadata 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.

129		-***CompType*:** CompType is the abstract base for any component value (e.g. a data or metadata attribute, or a measure) that cannot be represented as an XML attribute. For example, a repeated value, a text value in multiple languages, or a value with structured text (XHTML) cannot be expressed as an XML attribute. This type is meant to be restricted based on the component to restrict the cardinality and type of its Value element to conform to the component definition. The type of the value element should be restricted to common:SimpleValueType, common:TextValueType, or common:StructuredValueType. In addition, the id attribute should be restricted to be a fixed value with the component identifier. This restricted type based on the component can then be used on Comp elements by using the xsi:type to state the component being expressed and refine the contents of the element to the values allowed by the component.

153		-***ObsType*:** ObsType is the abstract type which defines the structure of a grouped or un-grouped observation. The observation must be provided a key, which is either a value for the dimension which is declared to be at the observation level if the observation is grouped, or a full set of values for all dimensions in the data structure definition if the observation is un-grouped. This key should disambiguate the observation within the context in which it is defined (e.g. there should not be another observation with the same dimension value in a series). The observation can contain an observed value and/or attribute values. Data structure definition schemas will derive a type or types based on this that is specific to the data structure definition and the variation of the format being expressed in the schema.

The metadata attribute values associated with the key dimensions will be expressed as XML local (non-namespace qualified) attributes if they are simple values (e.g. enumerated, dates, numbers) and are not repeatable. Metadata attributes that are repeatable, or do not have simple values (e.g. text) will be expressed using the Comp element.

The targets should conform to the restrictions described by the metadata provision or the metadataflow. Note that this is maintainable, and as such must specify in agency. In this case, the agency is the metadata provider. If a metadata provision agreement is referenced, it is assumed that the metadata provider described in the provision will be the same as the agency for this set.

SDMX web services that neither support the *updatedAfter* URL parameter might also implement physical deletions. However, SDMX web services that support these parameters (or other time-machine features), would not overwrite or delete the physical values.
	888	+The terms “//delete//”, “//merge//” and “//replace//” do **not** imply a physical replacement or deletion of values in the underlying database. To minimize the physical resource requirements, SDMX web service implementations that do not support the //includeHistory// and //asOf// URL parameters might physically replace the existing values in the database. SDMX web services that neither support the //updatedAfter// URL parameter might also implement physical deletions. However, SDMX web services that support these parameters (or other time-machine features), would not overwrite or delete the physical values.

860		-SDMX web services that support the *includeHistory* or *asOf* URL parameters should never allow deleting their **historic** data content because this would interfere with the interests of data consumers, such as data aggregators. Therefore, a specific feature to physically delete previous (outdated) content is intentionally not added to the SDMX standard syntax. If such a feature is required by an organisation, then it needs to be implemented as a custom feature outside the SDMX standard.

These datasets are to be processed in the order of appearance in the message. The advantage of such data messages is thus the ability to bundle separate *delete* and *replace* or *merge* actions into one transactional data message.

Consequently, different actions cannot be bundled and executed with “transactional ACIDity”. Note that metadatasets retrieved using the HTTP header “Accept-Language” may contain only partial languages, and thus should be marked with its *isPartialLanguage* property set to true. Submitting such a partial metadataset to update an SDMX storage system will only add or update the included languages but not change other languages.
