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.
cto
CTO
Local identifiers in Clinical Trials Ontology should match this
regular expression:
^\d{7}$
Compact URIs (CURIEs) constructed from Clinical Trials Ontology should match
this regular expression:
^cto:\d{7}$
The metaregistry provides mappings between the Bioregistry and other registries. There are
6 mappings to external registries for cto
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
Providers are various services that resolve CURIEs to URLs. The example CURIE
cto:0000022
is used to demonstrate the provides available for
cto
. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
