In the SemanticWeb, URIs are used to support a marketplace of terms.

In DTS (#268), all namespaces are either by subscription or local. There is no concept of a marketplace, of terminologies, from afternoon-hack to small workgroup product to multi-site collaboration to commercial product or open standard. To be fair, that is what it says on the tin:

Apelon DTS integrates standard vocabulary, including local enhancements, into an enterprise healthcare-computing environment. -- DTS Server Guide

And like i2b2, there are no URIs for concepts/terms, unfortunately. I think I explained why that's important in my 2009 project report; if not, I should find a good written argument. If nothing else, it's a backbone concept in OWL, a W3C standard with a lot of application in biomedical informatics:

Key bio-medical ontologies, such as SNOMED-CT and the NCI thesaurus migrated to OWL and to an OWL based toolchain, allowing them to move from proprietory[sic] languages and their vender[sic] locked in toolchains.

NCI Thesaurus in OWL

A caBIG page on the NCI Thesaurus says "The NCI Thesaurus is authored using the open-source Protege editor. On a monthly basis the Thesaurus is exported as an OWL file for publication." ooh! EVS Downloads says "EVS encourages you to begin using NCI Thesaurus in the Web Ontology Language (OWL). " And lo: Thesaurus.owl


Where are the SNOMED-in-OWL bits? Not clear that they're published, but see:

Unlocking SNOMED-CT for the uninitiated

SNOMED CT, even when presented in the more user-friendly Manchester OWL syntax, can be impenetrable to the uninitiated. To address this problem, we have developed a system (named OntoVerbal?) that automatically translates SNOMED CT concepts/classes into natural language text. We invite you to help us test the system by participating in a short (20 min) experiment that involves reading 10 such texts and translating them back into the corresponding OWL.

Ontology/Concept Mapping

Possible tool:

The CTSA Health Ontology Mapper (HOM) is an open source general purpose instance mapper running as an i2b2 cell designed for academic research and hospital environments. It can convert locally obtained data (which may not be encoded using any nationally recognized standard format) into standard ontologies as defined by the IEC111-79 data model format
