7.1 concept system: This is not used separately, but rather in conjuction with a concept position in datcat 7.2. The concept system becomes a refObject that is pointed to. See A.7.2
7.2 concept position
Description: The position of a concept in a concept system.
Blind MARTIF Representation A.7.2: <ref type=conceptPosition target=Y>...</ref>, where Y is the refid of a <refObject type=conceptSystem>
Note 1: This is the same format as A.4.2, but a concept system is usually more restricted than a classification system; a concept system may be a detailed analysis of the concepts in one subject field or identifier in a classification system.
Note 2: Types of concept position (content) can include:
The second format is for when there is not a formal concept system:
Blind MARTIF Representation of A.7.2.*: <ref type=X target=Z>...</ref>, where X is the name of the relation to the other concept (listed above) and Z is the refid of another termEntry and the content is a name for the implicit concept system.
7.2.1 broader concept generic/partitive
Description: A concept two or more levels of abstraction higher than subject concept in a hierarchical concept system.
Note: Broader concepts can occur in either a generic or a partitive concept system.
7.2.2 superordinate concept generic/partitive
Description: A concept in a hierarchical system that can be subdivided into a number of lower-ranking concepts.
Note 1: For definition of related term, see ISO 1087:1990, 3.1.2
Note 2: In generic concept systems, a superordinate concept constitutes the concept itself, whereas the common linguistic term "hyperonym" references the term that represents the concept. Superordinate concepts in partitive systems can also be called comprehensive concepts.
7.2.3 subordinate concept generic/partitive
Description: A concept in a hierarchical system that can be grouped together with at least one more concept of the same level to form a higher ranking concept.
Note 1: For definition of related term, see ISO 1087:1990, 3.1.3
Note 2: "Subordinate concept" emphasizes the concept itself, whereas the common linguistic term "hyponym" references the term that represents the concept. Subordinate concepts in generic systems can be called specific concepts. In partitive concept systems, subordinate concepts can be called partitive concepts.
Note 3: The subordinate concept data category must be hierarchically iterative in order to account for deeper levels of abstraction. In Annex C, Figure C.6, for instance, if the bones of the wrist were viewed as divided into separate regions, an additional level of abstraction would be introduced into the system requiring a deeper level of subordination.
7.2.4 coordinate concept generic/partitive
Description: A concept in a hierarchical system that ranks at the same level as one or more other concepts.
Note 1: For definition of related term, see ISO 1087:1990, 3.1.4
Note 2: Coordinate concept designates the concept itself, whereas the common linguistic term co-hyponym references the term that represents the concept.
7.2.5 related concept
Description: A concept that has an associative relation to another concept.
Example: "Teacher" and "school" are related concepts.
