## Notes

Apache Casbin is an access control library for Go. An application loads an access model and a policy, then asks the library whether a request is allowed. The model and policy cover the ACL, RBAC and ABAC models, and the library is installed as a Go module.

The homepage names MySQL, Postgres, Oracle and MongoDB among the storage backends. Ports in other languages, such as node-casbin and PyCasbin, are separate projects under the same name. The project is an incubating project of the Apache Software Foundation.
