Controlled vocabularies (also known as code systems or terminologies) are common information artefacts in healthcare. They allow for univocally and precisely referencing of concepts and are core foundation of any semantic processing of health data. In particular all electronic communication in healthcare relies on coded concepts for semantic interoperability and automated data processing.
The Object Management Group's Common Terminology Services Version 2 (CTS2) standard defines an accepted industry standard service interface to share, query and maintain value sets and other terminology artifacts. The CTS2 specification is structured within a platform independent model that provides two profiles:
- Structural profiles define how code systems, associations, or value sets are organized;
- Functional profiles define fundamental operations of persistent storage (CRUD) in an information system that change these structures.
One method to achieve compliance with the structural profiles of CTS2 is to use semantic web technologies that are widely used for vocabularies. In this way, CTS2 artifacts such as code systems, code system elements (i.e., codes and their designations), associations and value sets (i.e., sets of code system elements) can be processed with reasoning engines including code member validations. CTS2-LE follows that foundation. It relies on the Resource Description Framework Schema (RDFS) in conjunction with a schema vocabulary oriented towards the Frame Logic. So-called RDF signatures, based on this schema vocabulary, describe structural constraints according to the CTS2 information model. Likewise, arbitrary object graphs can be processed and stored with these RDF signatures.

CTS2-LE Overview
This section provides an overview about CTS2-LE. It introduces the CTS2-LE building blocks and summarizes the most important functional features provided by CTS2-LE.
CTS2-LE Installation, Deployment, and Setup
This section covers the installation and initial setup of CTS-LE within an organization.
- Prerequisites for CTS2-LE Installation
- This section describes the hardware, OS and network requirements for installing CTS2-LE as a stand-alone-system on a server.
- CTS2-LE Installation and Deployment
- CTS2-LE is provided as a set of libraries and executables for the various system building blocks. This section describes how to deploy, configure and activate these components for specific usage scenarios.
- CTS2-LE Loadbalancing
- For deployments with outstanding requirements on availability and performance, CTS2-LE can be configured to run with multiple instances behind a load balancer. This section describes how a respective deployment can be set up.
- CTS2-LE Security Configuration
- CTS2-LE standard configuration allows unrestricted read access while administrative functionalities (e. g. loading/updating terminologies) is restricted to registered named users. This section describes how to configure these defaut security settings and how enhanced security services (e. g. full access control) may be linked with CTS2-LE.
- Loading Core Terminologies
- All standard terminologies (ICD-10, LOINC, etc.) require the user to obtain an individual license. Therefore such terminologies are not part of the CTS2-LE distribution but have to be licenced and loaded by the CTS2-LE customer. To ease this process, the CTS2-LE distribution includes a set of "terminology loaders" which allow for an automatic integration of the most common standard terminologies into CTS2-LE. This section describes how these loaders can be installed and activated for loading standard terminologies into CTS2-LE.
- Loading Pre-Defined Value Sets
- HL7v3 and FHIR make intense use of value sets as defined by various HL7 committees. These value sets refer to standard terminologies and limit these to the sets of concepts required for common use cases. The CTS2-LE distribution includes the most important HL7v3 and FHIR value sets in a standard format. This section describes how these value sets can be loaded into CTS2-LE.
- CTS2-LE Update Procedures
- Fraunhofer FOKUS will provide regular updates to the CTS2-LE software and loaders. These updates will include bug fixes, adaptations to changes on the CTS2 standard, and additional functionality. This section describes how to install an update to an already deployed CTS2-LE.
