--//**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). 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 (data and metadata 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, 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 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.

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.

--//**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 dimension value(s) which make up the key and the data and metadata attribute values associated with the key dimension(s) or the primary measure will be represented with XML attributes. This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived observation 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 attribute(s) 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 observation type be for the observation dimension(s) 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.

  **Important notes:**
--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.
++The terms “//delete//”, “//merge//” and “//replace//” do **not** imply a physical replacement or deletion of values in the underlying database.

However, SDMX web services that support these parameters (or other time-machine features), would not overwrite or delete the physical values.
--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.

--All datasets – even with varying actions – within a single data message have always to be treated as **ACID transaction** to guarantee “transactional safety” (full data consistency and validity despite errors, power failures, and other mishaps). 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.

  == 4.2 Reference Metadata Actions ==
  Reference metadata defined by a Metadataflow or a MetadataProvisionAgreement are exchanged within reference metadatasets, which are maintainable and thus for actions behave like structural metadata (artefacts): When interacting with SDMX Rest web services, the HTTP action verbs GET, PUT and POST are used to indicate the intended action per web request. 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.
  The former message header or metadataset property *DataSetAction* is deprecated. To avoid conflicts, it is now ignored if still present.
