dataquay

Dataquay is a free open source library that provides a friendly C++ interface to an RDF datastore using Qt4 classes and containers. Supported datastores are the popular and feature-complete Redland and the lightweight Sord. Dataquay is simple to use and easy to integrate. It is principally aimed at Qt-based applications that would like to use an RDF datastore as backing for in-memory project data, to avoid having to invent file formats or XML schemas and to make it easy to augment the data with descriptive metadata pulled in from external sources. It's also useful for applications with ad-hoc needs for metadata management using RDF sources. Dataquay does not use a separate database, instead using in-memory storage with separate file import and export facilities. Although it offers a choice of datastore implementations, the choice is made at compile time: there is no runtime module system to take into account when deploying your application. The Fedora package is configured to use Redland, as recommended by the developers for general use.
