External relationships (unlike Internal relationships) exist between LOCs and items outside of the source structure or framework, including hierarchical relationships. This could be, for example to indicate equivalent LOCs in other structures.
Items are related in various ways to items with relationships such as equivalence, prerequisite, is part/has part.
Please specify the relationships used.
Note that we are only interested in relationships between LOCs.
One set of relationships that are designed for this kind of use are the SKOS mapping properties.
- eCOTOOL defines cross-mapping relationships. Cross-mapping relations relate two concept definitions that are not in the same framework. Logically they are quite different from structural relations within a framework, because while structural relations are inherently defined by their framework, in contrast cross-mapping relations have no one authority responsible for defining them. Opinions may differ by authority.
- We need to have examples, or just statements from stakeholders, about practical requirements in this area.
