Persevere
Persevere is designed to create applications with user interface implemented primarily on the client side and Persevere playing the role as an HTTP-based RESTful data provider.
Persevere is not an MVC framework, it is built to be the data model (the "M" in the MVC), such that the the viewer and controller can be cleanly implemented separately (typically on the client side). Persevere works beautifully as the server for Ajax-style JSON-based web applications, and can easily be complimented with other types of user interfaces such as an iPhone app, all using the same convenient server interface. One can certainly add viewer and controller technologies to Persevere, but that is not part of the core infrastructure.
Persevere is a framework composed of several modular autononmous packages that provide different functionality, and cohesively come together to provide a complete RESTful server data storage solution.
