class kazu.database.in_memory_db.MetadataDatabase[source]

Bases: object

Singleton of Ontology metadata database.

Purpose: metadata needs to be looked up in different linking processes, and this singleton allows us to load it once/reduce memory usage

__init__()[source]
add_parser(name, entity_class, metadata)[source]

Add metadata to the ontology. Note, metadata is assumed to be static, and global. Calling this function will override any existing entries with associated with the keys in the metadata dict.

Parameters:

  • name (str) – name of ontology to add to

  • entity_class (str) – entity class this parser maps to

  • metadata (dict[str, dict[str, Any]]) – dict in format {idx:metadata}

Returns:

Return type:

None

get_all(name)[source]

Get all metadata associated with an ontology.

Parameters:

name (str) – name of ontology
