Introduction

The Asserted Value Set services are integrated parts of the LexEVS API. It provide several functions:

Getting Source Asserted Value Sets as CodingScheme or Coding Scheme reference objects

Getting the entities of Source Asserted Value Sets as ResolvedConceptReference objects as Lists or Iterators

Getting a list of all unique identifiers of value set top nodes from this source terminology

Getting a list of all schemes used to resolve a given set of values from a resolved value set coding scheme

Most coding scheme representations and entity reference sets are resolved by the unique URL of the coding scheme.  Some allow a definition of a concept or text match.  All methods offer a resolution service to some set of values.  These mechanisms are largely read functions requiring a listing of known values or an exact match of a unique identifier.  Only one offers what could be classified as a search.

LexEVS Asserted Value Set Definition Services API

LexEVS Value Set Definition Services provides three major functions:

Each of these functions are described in following sections.

 

List Functions

List All Value Sets As Fully Populated Coding Schemes

listAllSourceAssertedValueSets()

Description:

Lists all coding schemes each with its own entity set fully resolved

Input:

none

Output:

List<CodingScheme>

Exception:

LBException

Implementation Details:

Implementation:
Step 1: Call this method on the associated LexEVS Asserted Value Set service instance to list a full set of coding schemes along with all of their entities
Sample Call:

  • Step 1:Instantiate SourceAssertedValueSetService if it is not done yet:

    org.lexgrid.valuesets.SourceAssertedValueSetServiceImpl  assVSServ = new SourceAssertedValueSetServiceImpl(new AssertedValueSetParameters.Builder().build());
    
  • Step 2: List all the coding scheme representations of the value sets

    List<CodingScheme> schemes = assVSService.listAllSourceAssertedValueSets(); 
    

     

     

 

List all Coding Schemes without entities

getMinimalSourceAssertedValueSetSchemes()

 

 

Description:

Lists all coding schemes – no entities resolved

Input:

none

Output:

List<CodingScheme>

Exception:

LBException

Implementation Details:

Implementation:
Step 1: Call this method on the associated LexEVS Asserted Value Set service instance to list a full set of coding schemes along with all of their entities
Sample Call:

  • Step 1:Instantiate SourceAssertedValueSetService if it is not done yet:

    org.lexgrid.valuesets.SourceAssertedValueSetServiceImpl  assVSServ = new SourceAssertedValueSetServiceImpl(new AssertedValueSetParameters.Builder().build());
    
  • Step 2: List all the coding scheme representations of the value sets

    List<CodingScheme> schemes = assVSService.getMinimalSourceAssertedValueSetSchemes();
