Prefixes for namespaces, primarily sourced from ROBOT, that cover most uses in OBO Foundry ontologies, with slight modification to match the prefixes as used in the Human Disease Ontology and a few additional prefixes for cross-references and DO-related SPARQL query support. These prefixes should be up-to-date with the latest OBO Foundry ontologies (https://github.com/ontodev/robot/issues/51).

Usage

Format

Character vectors of namespaces named by their corresponding prefix:

ns_prefix: Superset of all 546 prefix/namespaces listed below.

not_obo_prefix: 21 prefix/namespaces outside but commonly used in the OBO Foundry (e.g. dc = "http://purl.org/dc/elements/1.1/"), or in federated SPARQL queries with the DO (e.g. up = "http://purl.uniprot.org/core/").

obo_prefix: Superset of all 525 OBO Foundry prefix/namespaces, including those listed below and, additionally, including the general obo prefix.

obo_ont_prefix: 261 OBO Foundry ontology primary prefix/namespaces (e.g. AAO = "http://purl.obolibrary.org/obo/AAO_").

obo_prop_prefix: oboInOwl (along with the common prefix variant oio) and 262 OBO Foundry ontology property namespaces (these may not all be in actual use) (e.g. aao = "http://purl.obolibrary.org/obo/aao#")
