The Orphanet Rare Disease ontology (ORDO) is a structured vocabulary for rare diseases, capturing relationships between diseases, genes and other relevant features which will form a useful resource for the computational analysis of rare diseases. It integrates a nosology (classification of rare diseases), relationships (gene-disease relations, epiemological data) and connections with other terminologies (MeSH, UMLS, MedDRA), databases (OMIM, UniProtKB, HGNC, ensembl, Reactome, IUPHAR, Geantlas) and classifications (ICD10).

Pattern for Local Unique Identifiers

Local identifiers in Orphanet Rare Disease Ontology should match this regular expression:
^C?\d+$

Example Local Unique Identifiers

C023   Resolve
478   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Orphanet Rare Disease Ontology should match this regular expression:
^orphanet\.ordo:C?\d+$

Example CURIEs

orphanet.ordo:C023
orphanet.ordo:478

Namespace Embedded in LUI

This resource has been annotated by the Bioregistry as having a potential namespace embedded in LUI. This means that you may see local unique identifiers that include a redundant prefix and delimiter (also known as a banana) and therefore look like a CURIE. For Orphanet Rare Disease Ontology, the banana looks like Orphanet_. Therefore, you may see local unique identifiers for this resource that look like Orphanet_C023 (instead of the canonical form C023) and CURIEs for this resource that look like orphanet.ordo:Orphanet_C023 (instead of the canonical form orphanet.ordo:C023). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

The metaregistry provides mappings between the Bioregistry and other registries. There are 9 mappings to external registries for orphanet.ordo with 4 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE orphanet.ordo:C023 is used to demonstrate the provides available for orphanet.ordo. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
