ID values of all elements in codeBook/stdyDscr/dataAccs of the document that describe access conditions for this nCube group.

Methodology and processing, references which record the ID values of all elements within the study methodology and processing section of the Study Description which might apply to the group. These elements include information on data collection and data appraisal (e.g., sampling, sources, weighting, data cleaning, response rates, and sampling error estimates).

A name, or short label, for the group.

Space delimited list of the IDs of all the nCubes that are immediate children of the nCube group.

Space delimited list of the IDs of all the nCube groups that are immediate children of the nCube group. The inclusion of a nCubeGrp brings in all of its members. Members of the included nCubeGrp should not be separately listed in either "nCube" or "nCubeGrp".

Should only be used when applying a controlled vocabulary, and when the type attribute has been given a value of "other". Use the complex element controlledVocabUsed to identify the controlled vocabulary to which the selected term belongs.

Link to publication/citation references and records the ID values of all citations elements within Section codeBook/stdyDscr/othrStdyMat or codeBook/otherMat that pertain to this nCube group.

Summary data description references that record the ID values of all elements within the summary data description section of the Study Description that might apply to the group. These elements include: time period covered, date of collection, nation or country, geographic coverage, geographic unit, unit of analysis, universe, and kind of data.

General type of grouping of the nCubes. Specific nCube Groups, included within the 'type' attribute, are:

- display: nCubes that are part of the same presentation table.

- subject: nCubes that address a common topic or subject, e.g., income, poverty, children.

- iteration: nCubes that appear in different sections of the data file measuring a common subject in different ways, e.g., using different universes, units of measurement, etc.

- pragmatic: An nCube group without shared properties.

- record: nCubes from a single record in a hierarchical file.

- file: nCube from a single file in a multifile study.

- other: nCubes that do not fit easily into any of the categories listed above, e.g., a group of nCubes whose documentation is in another language. A term from a controlled vocabulary may be placed into the otherType attribute if this value is used.
