All TSV files produced should come with a SSSOM-style header

[matentzn]

Headers are valid #-commented yaml files. We use them like:

# ontology: upheno1
# branches:
#   - HP:123
#   - MP:123
# similarity_measure: jaccard
# similarity_threshold: 0.7
# tool: semsimian
# tool_version: 0.0.1
subject_id  object_id   diff
....

This is will drastically reduce file sizes. See SSSOM for example implementation.
