Web Service Method: Request Paths Between Concept and Concept Schemes

02/04/2026

Description
Returns a list of all existing paths between the requested concept and all concept schemes it is located in.

URL: /PoolParty/api/thesaurus/{project}/paths

This service can be used to provide hierarchical breadcrumb functionality, which is often used as navigation element: https://en.wikipedia.org/wiki/Breadcrumb_(navigation)

The list always starts with a Concept Scheme, with the title as preferred label. Multiple paths can emerge when a polyhierarchy exists.

Note

This request is the opposite of the Web Service Method: Request Subtree of Concept or Concept Scheme where you use for example a concept scheme to retrieve all the concepts it contains.

As such, these mixed drinks are some of the most notable and frequently-made cocktails by professional bartenders around the world. IBA Cocktails are specified in centilitres (cl) rather than the more commonly used millilitres (ml). 3 cl are approximately equivalent to 1 U.S. fluid ounce (1.4% more)."
