CTS2-LE REST API: Read Entity Descriptions

Root-URL: /WebCts2LE/rest/

Retrieve all top level concepts of a code system version

• this service is a restricted version of the standard REST call with uri /codesystem/{codesystemid}/version/{codesystemversionid}/entities; it cannot be used to retrieve all entities of a code system version but only the top level concepts
• Path: /codesystem/{codesystemid}/version/{codesystemversionid}/entities
• Method: GET
• Path Parameters:

codesytemid the Name of the Code System - will be ignored

codesystemversionid the Name (version ID) of the Code System Version, set to '_def' to request the default version

• Query Parameters:

codesystemuri the URI that references a code system, e.g. http://www.nlm.nih.gov/mesh14 for the MeSH vocabulary

filtercomponent the name or URI of the property or model element to be filtered. Properties are referenced by their predicate and model elements all have URI's that are established by this specification. This service supports the following filter components: 'toplevel' returns only the top level entities (entities that have no parents and are ranked first in a hierarchy). At the moment, this is the only filtercomponent value and it has to be present in any call.

• returns: entity:EntityList
