Orion is a constellation located on the celestial equator that you can easily see from the Northern hemisphere.
It is also an awesome Eclipse project that just opened up its own blog so you can follow the news for the project. I eluded to the Domino Designer being a 100% web based developer tool before and as Orion matures it is becoming more and more possible. Could Designer on the cloud let Lotus developers compete with the likes of salesforce.com? I don’t know but the concepts of web based development or even web based rich applications is becoming more real today then ever before.
Orion is a proposed new open source project under the Eclipse top-level project. The project is currently in the Pre-Proposal phase. To facilitate gathering of a community for this new project, an initial code contribution has been made within the E4 incubator.
