--//**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.

--|type|IDType|(% style="width:648px" %)The type attribute is used when the derived format requires that explicit measure be used. In this case, the derived type based on the measure will fix this value to be the identification of the measure concept.

--***AttsType*:** AttsType is the abstract type which defines a structure which is used to group a collection of data or metadata attributes which have a key in common. The key for a attribute collection is a subset of the dimension defined in the data structure definition. This is also used for data set level attributes (i.e. those with an attribute relationship of none). In this case, the subset of dimensions is empty. Data structure definition schemas will derive a type based on this that is specific to the data structure definition. The dimension values which make up the key will be represented with local (non-namespace qualified) XML attributes. 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. These dimensions and simple attributes are specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived series 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).

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.
