Global Elements

ConceptualComponent (ConceptualComponentType): Concept, Universe, and Geography schemes used by the data being documented, or references to those schemes.

Concept (ConceptType): Container for an individual concept included in the concept scheme.

CharacteristicReference (ConceptReferenceType): References a concept which has its isCharacteristic attribute set to true.

DataElementConcept (DataElementConceptType): Container for a data element concept (per ISO/IEC 11179) included in the concept scheme.

UniverseReference (r:ReferenceType): Reference to the universe which is associated with the data element concept.

Title (r:InternationalStringType): Full title of vocabulary.

Abbreviation (r:InternationalStringType): Abbreviation of vocabulary title.

Keyword (r:InternationalStringType): Keywords that describe the vocabulary.

ConceptScheme (ConceptSchemeType): Includes a comprehensive list of the concepts describing the data that are being documented.

ConceptSchemeReference (r:SchemeReferenceType): References a concept scheme external to this module, for inclusion in the module.

UniverseScheme (UniverseSchemeType): Includes a comprehensive list of the universes and sub-universes for the data that are being documented.

UniverseSchemeReference (r:SchemeReferenceType): References a universe scheme external to this module, for inclusion in the module.

Universe (UniverseType): Describes a universe for inclusion in the module.

SubUniverse (UniverseType): A subset of the parent universe for example the universe Females is a subset of the universe Population.

HumanReadable (r:StructuredStringType): A human-readable statement of the Universe of the question item.

MachineReadable (r:CodeType): A machine-readable statement of the universe, expressed as a Coding.

Vocabulary (VocabularyType): Provides information about the vocabulary used to create the concept scheme.

ConceptGroup (ConceptGroupType): Allows for grouping of concepts; groups may have a hierarchical structure.

ConceptReference (ConceptReferenceType): Reference to a concept included in the concept group. A concept can be referenced internally, from the concept scheme included in the same conceptual components module, or externally, from another scheme. This element is recursive to allow for the description of hierarchical relationships within the concept group.

Comments (r:StructuredStringType): Human-readable comments on the usage of the vocabulary.

SimilarConcept (SimilarConceptType): Reference to another concept that is similar to the one included in the Description element above.

Difference (r:StructuredStringType): Describes the difference between the concept referenced in ConceptReference and the concept included in the concept's Description element.

GeographicStructureScheme (GeographicStructureSchemeType): Contains a collection of geographic structures.

GeographicStructureSchemeReference (r:SchemeReferenceType): A reference to an internal or external geographic structure scheme in DDI 3.0 XML.

GeographicLocationScheme (GeographicLocationSchemeType): Contains a collection of geographic locations.

GeographicLocationSchemeReference (r:SchemeReferenceType): A reference to an internal or external geographic location scheme coded in DDI 3.0 XML.


Complex Types

ConceptualComponentType: Concept, Universe, and Geography schemes used by the data being documented, or references to those schemes.

ConceptSchemeType: Includes a comprehensive list of the concepts measured by the data that are being documented.

UniverseSchemeType: Includes a comprehensive list of the universes and sub-universes of the data that are being documented.

ConceptGroupType: Allows for grouping of concepts; groups may have a hierarchical structure.

ConceptReferenceType: References concepts to be included in concept groups.

VocabularyType: Provides information about the vocabulary used to create a concept scheme.

ConceptType: Container for an individual concept included in the concept scheme.

DataElementConceptType: Container for a data element concept (per ISO/IEC 11179) included in the concept scheme.

SimilarConceptType: Reference to another concept that is similar to the one included in the Description element above.

UniverseType: Universe statement associated with the data.

GeographicStructureSchemeType: This scheme contains a set of geographic structure types and their relationship to each other. For example, the structure types in the U.S. Census geographic hierarchy used in summary files.

GeographicLocationSchemeType: This scheme contains a set of geographic locations, each for a single Geography type, e.g., States OR Counties, OR Countries, etc. The geographic location element has to be repeated for each geography structure type described.
