Annotation
Describes the logical record in terms of identification of its type, case identification, its relationship with other records, and support for multiple storage segments. Required to link a description of a physical record structure to its logical record.

hasLocator-
Type: |
xs:boolean, predefined |
Use: |
required |
Indicates if the record type has a field which identifies its record type. In logical structures with a single record type there is generally no identifier. Most multi-record files will have a variable that identifies the record type.

There may be more than one means of identifying a record. For example a US Census Summary File has a LogicalRecordIdentifer that is unique to the original file within which it was published. A specific geography has a set of fields that identify it uniquely.

List of all NCubes used in the record, either directly or as found in a defined NCubeGroup; note that an NCube can be used in multiple records. The NCubes in the logical record can be noted by inclusion or exclusion to facilitate listing. The attribute allNCubesInLogicalProduct, when set to 'true', includes all NCubes in the LogicalProduct. NCubeSchemeReference can then be used to exclude individual NCubes schemes or include schemes from other logical products. In the same way NCubeReference can be used to exclude specific variables from the previously defined variable set or include variables not already included. The simplest LogicalProduct descriptions with a single LogicalRecord can be described using only the attribute allNCubesInLogicalProduct with a value of true.

Information concerning support for breaking the logical record into segments for storage purposes. Some files may be broken into record segments for storage but lack variables to support identification of specific segments. In this case segments are identified by their physical order within the storage file.

List of all variables used in the record, either directly or as found in a defined VariableGroup; note that a variable can be used in multiple records. The variables in the logical record can be noted by inclusion or exclusion to facilitate listing. The attribute allVariablesInLogicalProduct, when set to 'true', includes all variables in the LogicalProduct. VariableSchemeReference can then be used to exclude individual Variables schemes or include schemes from other logical products. In the same way VariableReference can be used to exclude specific variables from the previously defined variable set or include variables not already included. The simplest LogicalProduct descriptions with a single LogicalRecord can be described using only the attribute allVariablesInLogicalProduct with a value of true.
