The core Ontology of Clinical Trials (CTO) will serve as a structured resource integrating basic terms and concepts in the context of clinical trials. Thereby covering clinicaltrails.gov. CoreCTO will serve as a basic ontology to generate extended versions for specific applications such as annotation of variables in study documents from clinical trials.

2020 CTO: a Community-Based Clinical Trial Ontology and its Applications in PubChemRDF and SCAIView

The metaregistry provides mappings between the Bioregistry and other registries. There are 6 mappings to external registries for this resource with 2 unique external prefixes.

When using this resource in RDF, the following URI format should be used:

http://purl.obolibrary.org/obo/CTO_$1

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier 0000022 is used to demonstrate the providers available for Clinical Trials Ontology. A guide for curating additional providers can be found here.
