This interface represents the core interface to a LexEVS service and acts as an entry point to other API components and services

A virtual graph where the edges represent associations and the nodes represent concept codes. A CodedNodeGraph describes a graph that can be combined with other graphs, queried or resolved into an actual graph rendering.

A coded node set represents a flat list of coded entries.

The service manager provides a single write and update access point for all of a service's content. The service manager allows new coding schemes to be validated and loaded, existing coding schemes to be retired and removed and the status of various coding schemes to be updated and changed.

Interface to perform system-wide query over optionally loaded metadata for loaded code systems and providers.

Authoring service interface for creating Mappings and Coding Scheme relationships

The LexBIGService interface is not an entry point for Value Sets and Pick Lists. For details, see the Value Set and Pick List Services section of this guide.

Marks a class as an extension to the LexEVS application programming interface. This allows for centralized registration, lookup, and access to defined functions.

Allows registration and lookup of implementers for extensible pieces of the LexEVS architecture.

Allows for additional filtering of query results.

Allows for unique sorting of query results. This interface provides a comparator to evaluate order of any two given items from the result set.

Allows for unique search of query results.

The loader interface validates and/or loads content for a service.

Validates and/or loads content provided in the LexGrid canonical XML format.

Validates and/or loads the complete NCI MetaThesaurus. Content is supplied in RRF format. Note: To load individual coding schemes, consider using the UMLS_Loader as an alternative.

Validates and/or loads content provided in Open Biomedical Ontologies (OBO) text format.

Validates and/or loads content provided in Web Ontology Language (OWL) XML format.

A loader for delimited text type files. Text files come in one of two formats: indented code/designation pair or indented code/designation/description triples.

Load one or more coding schemes from UMLS RRF format stored in a SQL database.

Validates and/or loads content provided in metadata xml format. The only requirement of the xml file is that it be a valid xml file

A loader that takes the delimited NCI history file and applies it to a coding scheme.

Load an OBO change history file.

Load mappings between coding schemes from UMLS formatted MRMAP.RRF and MRSAT.RRF files.

Loads representations sourced in the Classification Markup Language such as ICD-10 ( No longer supported )

Loads the Radlex terminology from a Protege Frames formatted source. ( No longer supported )

Defines a class of object used to export content from the underlying LexGrid repository to another repository or file format.

Exports content to LexGrid canonical XML format.

Exports content to OBO text format.

Exports content to OWL XML format.

Identifies expected behavior and an associated loader to build and maintain a named index. Note that a single loader may be used to maintain multiple named indexes.

Manages registered index extensions. A single loader may be used to create and maintain multiple indexes over one or more coding schemes.

The generic extension class. Classes that implement this class are accessible via the LexBIGService interface.

Convenience methods to be implemented as a generic extension of the LexEVS API.

A grouping of Mapping Coding Scheme related functionality.

A grouping of Coding Scheme Supplement related functionality.

Helper class to ease creating common objects.

One-stop shopping for convenience methods that have been implemented against the LexEVS API.

Provides constants for use in the LexEVS API.

Provides centralized formatting of LexEVS Objects to String representations.

Provides utility methods for the LexEVS services.

Provides centralized formatting of LexEVS Value Set Object to String representations.

Generic interface for flexible resolution of LexEVS objects

An iterator for retrieving resolved coding scheme references.
