GridPort is a simple and robust open standard for portlets based on HTTP. It aims to be a simple, scalable distributed composition independent of implementation technology. Transparent collaboration and an SOA paradigm from both interface and data perspectives are encouraged. Component types include portal, proxy for asynchronous multi-casting, and portlets. The purpose of this project is to develop mainly the specification alongside a prototype to enable development of these components in any programming environment and operating platform, which is why its central protocol is HTTP 1.1.
