Version 1.0 of the JavaScript application server Persevere has been released by the developers. Persevere is a Dojo Foundation project that provides a JSON storage and JavaScript application server. Data can be stored schema free or with an optional class based schema. It provides a RESTful JSON interface for other client applications to read, create, update and delete data stored within the server and supports JSONQuery/JSONPath as a query language. Within the server, a JavaScript environment which uses Mozilla's Java implementation of JavaScript, Rhino, is accessible through JSON-RPC calls.

Persevere can handle real-time notification of changes in data with long polling and Comet and Bayeux support. Persevere can also be used as a front end to other databases through pluggable data sources, exposing existing tables, documents or other content through the REST API. Persevere is made available under the modified BSD Licence or the Academic Free Licence 2.1. The code is hosted on Persevere's Google Code project page. Documentation can be found on
