Metadata¶

class pronto.Metadata[source]¶

format_version¶

The OBO format version of the referenced ontology. 1.4 is the default since pronto can only parse and write OBO documents of that format version.

Type:: str

data_version¶

The OBO data version of the ontology, which is then expanded to the versionIRI if translated to OWL.

Type:: str or None

ontology¶

The identifier of the ontology, either as a short OBO identifier or as a full IRI.

Type:: str or None

date¶

The date the ontology was last modified, if any.

Type:: datetime or None

default_namespace¶

The default namespace to use for entity frames lacking a namespace clause.
