OpenCannabis is a multilateral industrial effort to bring order to cannabis data, via the power of collaborative spec design. The project covers expression of cannabis-related data in myriad supply chain circumstances, including cultivation, distribution, distillation (manufacturing), retail, and consumer-facing software.

This specification has been designed over time principally in the California cannabis market, which is one of the most competitive retail and wholesale cannabis markets in the world. Contributors and adopters include some of the best and brightest cannabis operators, who have condensed much of their knowledge into this model, and leveraged it for concrete operational gains.
