Introduction

The Asserted Value Set services are integrated parts of the LexEVS API. It provides 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 method offers what could be classified as a search.

LexEVS Asserted Value Set Search Services provides search methods with a variety of inputs

• Text to Match: unique identifier, presentation, or property value.
• Algorithm for Match: exact match, contains, lucene query parser type search
• Coding Scheme Reference: reference to source scheme(s)
• Coding Scheme Reference: reference to coding scheme representation of a value set
• Boolean: includes anonymous nodes
• Boolean: includes inactive nodes
