CTS 2 Standard Specification • CTS 2 is an OMG specification for representing, accessing, and disseminating terminological content. • The CTS 2 platform independent model (PIM) describes the formal model and semantics of the various components. • The PIM model is rendered in the Unified Modeling Language (UML) and its specification is publicly accessible at the OMG website. • As of April 2014, the CTS 2 version 1. 1 is the latest version released. © 2014 MFMER | slide-3

Objective of the study • To describe the existing WHO ICD-11 content services using the CTS 2 standard specifications. • We profiled the WHO ICD-11 content services using the information models of Code System Catalog, Code System Version Catalog, Entity Description and Association from the CTS 2 specification. • We also developed a prototype of the CTS 2 Wrapper Services for ICD-11. © 2014 MFMER | slide-4

Code System Catalog • ICD-11 Foundation (http: //id. who. int/icd/entity) • corresponds to the Top Level of the Foundation category • ICD-11 Morbidity (http: //id. who. int/release/11/morbidity) • corresponds to the Top Level of the ICD-11 Linerizations without minor version • ICD 10 (http: //id. who. int/release/10) • corresponds to the Top Level of the ICD 10 without minor version © 2014 MFMER | slide-6

Discussion • Versioning mechanism for ICD-11 Foundation would be a critical component. • The external identifiers for those values annotated by external terminologies should be exposed. • CTS 2 specifications also have the notions of Value Set Catalog, Value Set Definition and Map Catalog, that can be leveraged by ICD 11. © 2014 MFMER | slide-9

Summary • CTS 2 standard specification is a very useful tool for profiling the ICD-11 terminology content. • The outcome produced by this profiling would potentially enrich the WHO ICD-11 content representation and enable a robust and standards-based content services to better support the ICD-11 revision applications. © 2014 MFMER | slide-10
