Quince is a file-based RDF repository. It stores RDF in a simple indexed directory structure that allows for easy matching of triple patterns by subject, predicate or object. Because Quince uses the line-oriented NQuads format for its data files, it is also possible to use line-based diffs such as that provided by Git to tell what has changed in a Quince store.

Quince is being used to manage the RDF data in DataDock.io.
