Concept Resolution

Programmers access coded concepts by acquiring first a node set or graph. After specifying optional restrictions, the nodes in this set or graph can be resolved as a list of ConceptReference objects which in turn contain references to one or more Concept objects. The following example provides a simple query of concept codes:

Service Metadata Retrieval

The LexEVS system maintains service metadata which can provide client programs with information about code system content and assigned copyright/licensing information. Below is an brief example showing how to access and print some of this metadata:

Combinatorial Queries

One of the most powerful features of the LexEVS architecture is the ability to define multiple search and sort criteria without intermediate retrieval of data from the LexEVS service. Consider the following code snippet:
