hash_mapping

hash_mapping(mapping: SemanticMapping, converter: Converter) → str[source]

Hash the entire SSSOM semantic mapping record.

Parameters:

mapping – A semantic mapping
converter – A converter

Returns:

A hexadecimal representation of the FNV64 hash of the canonical S-expression for the mapping, proposed in https://github.com/mapping-commons/sssom/pull/534.

Note

This creates a hash over the entire SSSOM semantic mapping record. If you just want to hash the core triple (i.e., subject, predicate, predicate modifier, and object), then use hash_triple()
