?z?? ;http://www.SDMX.org/resources/SDMXML/schemas/v2_0/structure GroupType _BI_anyType?GroupType declares any useful groupings of data, based on a selection of the declared (non-Time) dimensions (indicated with the DimensionRef element) which form partial keys to which attributes may be attached. The value of the DimensionRef element is the concept of the dimension - that is, the value of the dimension's concept attribute. Thus, if data is to be presented as a set of time series which vary only according to their differing frequencies, a "sibling group" would be declared, with all dimensions except the frequency dimension in it. If data is commonly grouped as a set of all countries, then a "Country Group" could be declared, with all dimensions except the country dimension forming part of the partial key. Any dimension which is not part of a group has a value which varies at the series level (for time series formats). There is no requirement to have only a single dimension ommitted from a partial key - it can be any subset of the set of ordered dimensions (that is, all dimensions except the time dimension, which may never be declared as belonging to a group partial key). All groups declared in the key family must be unique - that is, you may not have duplicate partial keys. All groups must also be given unique names (id attributes). Although it is conventional to declare dimensions in the same order as they are declared in the ordered key, there is no requirement to do so - the ordering of the values of the key are taken from the order in which the dimensions are declared. The Description element provides a human-readable description (potentially in multiple, parallel languages) of the group. Note that for cross-sectional formats, the named group mechanism is not used, but is instead replaced by a generic group which carries time and frequency values with it, and allows for any available group-level attributes to be specified if desired.
