PSX is a PHP framework for creating RESTful APIs. It helps you to build clean URLs serving Web standard formats like JSON, XML, Atom, and RSS. It includes a handler system that abstracts away SQL queries from domain logic, a routing system that executes correct controller method for the location of the controller and the method annotation, and a flexible data system that converts database records into formats like JSON, XML, Atom, and RSS. A lightweight DI container handles dependencies. The controller supports request and response filters that can modify the HTTP request or response, and filters are provided for Basic and Oauth authentication.
Amun is a content management framework based on the PSX framework. The goal is to build a more federated and programmable Web. This is achieved by providing a RESTful API for managing and distributing the content in standard formats like JSON, XML, Atom, and RSS. It tries to support open standards like OAuth, OpenID, etc., and gives you the freedom to access the data of a Website in the way you like. It tries to enable easy communication from server to server, browser to server, and application to server.
