Why your AI agent can't connect the dots: ontology in 30 seconds
Nobody named the links between your data. An ontology does: supplier, part, product, customer, so a late supplier leads straight to the affected customers, Kestrel and Orbis.

print("affected:", sorted(found))Transcript
One supplier is late. Which customers get hurt? Your agent can miss it. The links sit in three systems.
An ontology names every link, like a family tree. Facts are triples: thing, relation, thing. Start at Acme. Follow the ontology: supplies, used in, ordered by.
Each hop keeps what links to what it found. Print who's affected. Run it: Kestrel and Orbis. Two customers, with the path as proof.
Name the links, and your agent can follow them.
