Guidelines for Semantic Information: Column 1 shows the guideline numbers; Column 2 shows the guideline descriptions; and Column 3 gives some examples of how to represent information according to the guidelines.
| No. | Guideline | Example |
|---|---|---|
| SKOS Route | ||
| S1a | Use skos:Concept for concepts that are not from OWL | Use skos:Concept to represent OBO terms |
| S2a | Defining any relationship or association between two concepts as an instance of owl:ObjectProperty and a sub-property of skos:semanticRelation | representing OBO relationships |
| S3a | Use rdfs:subClassOf for parent-child hierarchical relationships | Use rdfs:subClassOf to represent relationships such as OBO is_a and UMLS hasSubtype |
| S3a | Use skos:broader and skos:narrower to assert any kind of direct hierarchical link between two SKOS concepts [31] | Defining OBO part_of as a sub-property of skos:broader |
| S4a | Use skos:related to assert an associative link between two SKOS concepts [31] | Use skos:related to represent Mesh see_also |
| OWL Route | ||
| S1b | Use owl:Class for all the concepts | Use owl:Class to represent OBO terms |
| S2b | Use owl:ObjectProperty and assertions for relationships between two concepts | representing OBO relationships |
| S3b | Use rdfs:subClassOf for parent-child hierarchical relationships | Use rdfs:subClassOf to represent relationships such as OBO is_a and UMLS hasSubtype |
| S4b | Use owl:equivalentClass for stating the equivalence of two named classes | Use owl:equivalentClass to represent relationships such as UMLS same_as |
| S5b | Use owl:disjointWith to assert that the class extensions of the two class descriptions involved have no individuals in common | Use owl:disjointWith to represent relationships such as OBO disjoint_from |
| S6b | Use owl:intersectionOf to describe a class for which the class extension contains precisely those individuals that are members of the class extension of all class descriptions in the list. | Use owl:intersectionOf to represent relationships such as OBO intersection_of |
| S7b | Use owl:unionOf to describe an anonymous class for which the class extension contains those individuals that occur in at least one of the class extensions of the class descriptions in the list. | Use owl:unionOf to represent relationships such as OBO union_of |
| S8b | Use owl:complementOf to describe two classes that are complement to each other. | |
| S9b | Use owl:ObjectProperty, owl:DataTypeProperty, and owl:AnnotationProperty in a semantically correct way | e.g., owl:AnnotationProperty cannot be inherited by subclasses. |
