[nichtich]

Mapping slot mapping_justification is mandatory according to current SSSOM specification

[matentzn]

What mapping set is that referring to?

File mp_hp_example_embedded.sssom.tsv and mp_hp_example.sssom.tsv in https://github.com/mapping-commons/mesh-mappings/tree/main/mappings.

From https://mapping-commons.github.io/sssom/spec-model/:

Those slots are mandatory (including the mapping_justification slot: the SSSOM standard posits that there can be no mapping without some form of justification)
