For example, a blacklist of classes. http://purl.obolibrary.org/obo/IAO_8000011 external import ontology module http://purl.obolibrary.org/obo/IAO_8000005 import ontology module external import An imported ontology module that is derived from an external ontology. Derivation methods include the OWLAPI SLME approach. http://purl.obolibrary.org/obo/IAO_8000012 species subset ontology module http://purl.obolibrary.org/obo/IAO_8000006 subset ontology module taxon subset A subset ontology that is crafted to either include or exclude a taxonomic grouping of species. http://purl.obolibrary.org/obo/IAO_0000078 curation status specification http://purl.obolibrary.org/obo/IAO_0000102 data about an ontology part The curation status of the term. The allowed values come from an enumerated list of predefined terms.

For example, the Uberon-to-ZFA bridge module. http://purl.obolibrary.org/obo/IAO_8000007 curation subset ontology module http://purl.obolibrary.org/obo/IAO_8000006 subset ontology module A subset ontology that is intended as a whitelist for curators using the ontology. Such a subset will exclude classes that curators should not use for curation. http://purl.obolibrary.org/obo/IAO_8000008 analysis subset ontology module http://purl.obolibrary.org/obo/IAO_8000006 subset ontology module An ontology module that is intended for usage in analysis or discovery applications. http://purl.obolibrary.org/obo/IAO_8000013 reasoned ontology module http://purl.obolibrary.org/obo/IAO_8000000 ontology module An ontology module that contains axioms generated by a reasoner. The generated axioms are typically direct SubClassOf axioms, but other possibilities are available. http://purl.obolibrary.org/obo/IAO_8000014 generated ontology module http://purl.obolibrary.org/obo/IAO_8000000 ontology module An ontology module that is automatically generated, for example via a SPARQL query or via template and a CSV. http://purl.obolibrary.org/obo/IAO_8000015 template generated ontology module http://purl.obolibrary.org/obo/IAO_8000014 generated ontology module An ontology module that is automatically generated from a template specification and fillers for slots in that template. http://purl.obolibrary.org/obo/IAO_8000018 obo basic subset ontology module http://purl.obolibrary.org/obo/IAO_8000017 ontology module subsetted by expressivity A subset ontology that is designed for basic applications to continue to make certain simplifying assumptions; many of these simplifying assumptions were based on the initial version of the Gene Ontology, and have become enshrined in many popular and useful tools such as term enrichment tools. Examples of such assumptions include: traversing the ontology graph ignoring relationship types using a naive algorithm will not lead to cycles (i.e. the ontology is a DAG); every referenced term is declared in the ontology (i.e. there are no dangling clauses). An ontology is OBO Basic if and only if it has the following characteristics: DAG Unidirectional No Dangling Clauses Fully Asserted Fully Labeled No equivalence axioms Singly labeled edges No qualifier lists No disjointness axioms No owl-axioms header No imports http://purl.obolibrary.org/obo/IAO_8000000 ontology module http://purl.obolibrary.org/obo/IAO_0000102 data about an ontology part ontology file http://purl.obolibrary.org/obo/IAO_8000017 ontology module subsetted by expressivity http://purl.obolibrary.org/obo/IAO_8000006 subset ontology module http://purl.obolibrary.org/obo/IAO_0000027 data item http://purl.obolibrary.org/obo/IAO_0000030 information content entity http://purl.obolibrary.org/obo/IAO_8000016 taxonomic bridge ontology module http://purl.obolibrary.org/obo/IAO_8000004 bridge ontology module http://purl.obolibrary.org/obo/IAO_8000019 ontology module subsetted by OWL profile http://purl.obolibrary.org/obo/IAO_8000017 ontology module subsetted by expressivity http://purl.obolibrary.org/obo/IAO_8000020 EL++ ontology module http://purl.obolibrary.org/obo/IAO_8000019 ontology module subsetted by OWL profile http://purl.obolibrary.org/obo/IAO_0000030 information content entity
