The hierarchy services provide information about ontology, such as is_a transitive closure, precomputed by NCBO. The hierarchy services information is based on the <SubClass> & <SuperClass>. Those relations most of the time represent is_a hierarchies.
There are 3 major hierarchy services. All of them takes as argument:
- An ontology version id or an ontology virtual id (In that second case, the latest version of the ontology is used).
- A conceptId
- Optional arguments:
- level=<integer> - limits results to a given level in the hierarchy
- offset=<integer> – results offset (used for pagination)
- limit=<integer> – limits the number of results
Parent & Children services
- Signature: ./concepts/parents/{ontlogyVersionId}/{conceptId}[?{optional args}]
- Example: http://rest.bioontology.org/bioportal/concepts/parents/13578/Melanoma
