CTS2 Links for LexEVS 6.0

Introduction

LexEVS CTS2 Value Set Query API provides capability to query Value Sets available in the system and also to query the binding between Value Set and Concept Domain.

Interface

org.lexevs.cts2.query.ValueSetQueryOperation is the main interface for all the queries against Value Set. This interface can be accessed using main LexEVSCTS2 interface, like:

org.lexevs.cts2.query.ValueSetQueryOperation vsQueryOp = new org.lexevs.cts2.LexEvsCTS2Impl().getQueryOperation().getValueSetQueryOperation();

Query Functions

Here are the major query functions available using ValueSetQueryOperation interface:

listValueSets

This function returns value sets that are available in the system. Optionally, the list can be filtered by providing the criteria as input parameters.

listValueSets(String codeSystemId, String conceptDomainId, String usageContextId, String codeSystemURI, SortOption sortOption)

Description:

Lists the value sets that are available to the CTS 2 service.
