## Notes

Open Semantic Framework is a middleware API layer that exposes RDF datasets through RESTful web services and SPARQL endpoints. Its web services manage the content indexed in an instance, and the README points to the Open Semantic Framework Installer as the way to get started with it.

## Worth knowing
