Persistent Object Storage for Qt Quick
summary
A small, embeddable NoSQL service called Qt JSON DB stores QML/JavaScript objects with UUIDs, provides asynchronous C++ and QML APIs, and plugs straight into views via a JSON DB list model. The demo imports Flickr RSS into the database with a headless agent, shows cross-process notifications, and implements map/reduce manifest views (maps emit objects, reduces use add/subtract functions). Feature-complete for experimentation, it runs but is still tuning performance, indexes and robustness.
