Open Entity Database

In short: OilProcessingHub is built entity-first. Every process, machine, oilseed, material, tool, comparison, supplier and term is a structured entity with a permanent ID, field-level provenance (source, confidence, verified date) and relationships. This page lets you browse all 188 entities, and the whole dataset is open under CC BY 4.0.

How to use this database

Permanent IDs. Every entity has a stable ID (e.g. PRC-000001) that resolves at /id/<ID>/ — for example /id/PRC-000001/ — and always points to that entity even if its page URL changes. Provenance. Quantitative fields carry a source, a confidence level and a verified date. Machine-readable. The full data is downloadable as JSON below and is intended to be served via the data API.
