get_relation_mapping

get_relation_mapping(prefix, relation, target_prefix, **kwargs)[source]

Get relations from identifiers in the source prefix to target prefix with the given relation.

Warning

Assumes there’s only one version of the property for each term.

Example usage: get homology between HGNC and MGI:

>>> import pyobo
>>> human_mapt_hgnc_id = "6893"
>>> mouse_mapt_mgi_id = "97180"
>>> hgnc_mgi_orthology_mapping = pyobo.get_relation_mapping("hgnc", "ro:HOM0000017", "mgi")
>>> assert mouse_mapt_mgi_id == hgnc_mgi_orthology_mapping[human_mapt_hgnc_id]

Parameters:

prefix (str)
relation (NormalizedNamableReference | Referenced | Reference | NamedReference | tuple[str, str] | str)
target_prefix (str)
kwargs (Unpack[GetOntologyKwargs])

Return type:

Mapping[str, str]
