An NCube is a 1..n dimension structure which relates a set of individual values to each other by defining them within a matrix. The NCube may be the result of aggregations, cross-tabulation, time-series, etc. The NCube is described by its dimensions which are represented by categorical variables (variables with a set number of values of specific definition that can be used to identify a specific cell as part of a matrix address). The resulting cells can contain one or more measures, also defined by variables. In addition to the standard name, label, and description of the NCube, it contains a reference to a universe, defines both the normal source of the data in the cells and unit of analysis, the purpose of creating the structured data, the dimensions and measures, as well as the ability to attached any other attribute (i.e., footnote, cell or region specific note) to a specified area of the NCube. Three attribute serve as informational check values; dimensionCount, cellCount, and isClean.

The number of cells (measures) found in the NCube. Note that this is the number of cells produced by dimension structure not the number of cells containing data in a sparse NCube. Caution in using optional checksums is recommended. Conflict between checksums and the items being counted can cause problems with warning flags during processing.

A value of "true" indicates that all cells have the potential for content values. If set to "false" Attribute and CoordinateRegion should be used to define the sparse areas of the NCube, those that have no content by definition. For example a cross-tabulation between Household Type (Family, Non-Family) and Number of persons in Household (1,2,3,4,5,6,7+) would need an attribute for Family/1 Person as this will always be empty due to the definition of Family as two or more related persons.

Data Relationship is optional because a logical product can contain only a category scheme and/or code scheme.

A logical record is a description of all of the elements (variables or NCubes) related to a single case or analysis unit. Required to link a description of a physical record structure to its logical record. In addition to the standard name, label, and description, the structure identifies the variable designating its record type, describes case identification within the record type, indicates support for multiple storage segments, and defines a default set of missing values used by the record. In a data set with multiple records repeat to describe each logical record, such as a household, family, person, or event, record. A LogicalRecord is required to link a description of a physical record structure to its logical record.

The data set will contain a measurement value for each cell in the NCube rather than specifying the code values of the intersect points on the dimensions.

ValueRepresentation is the head of a substitution group which supports a number of representation types, i.e. CodeRepresentation, NumericRepresentation, TextRepresentation, DateTimeRepresentation, ScaleRepresentation, GeographicStructureCodeRepresentation, and GeographicLocationCodeRepresentation. Although the structure allows for specification of missing values these features should be used with caution. Like the definition of the universe and concept, the specification of the representation can be constrained by the Variable (the GSIM ImplementedVariable), for example a NumericRepresentation could be constrained with a lower top coding specification. Missing Values can be assigned separately by the Variable without impact on the ValueRepresentation of the specified valid values provided here.

A Statistical Classification is a set of categories which may be assigned to one or more variables registered in statistical surveys or administrative files, and used in the production and dissemination of statistics. The categories at each level of the classification structure must be mutually exclusive and jointly exhaustive of all objects/units in the population of interest. The categories are defined with reference to one or more characteristics of a particular population of units of observation. A Statistical Classification may have a flat, linear structure or may be hierarchically structured, such that all categories at lower Levels are sub-categories of categories at the next Level up. Categories in Statistical Classifications are represented in the information model as Classification Items.
