NoseRub
NoseRub is a project started by Dirk Olbertz of Blogscout fame. The idea of NoseRub is that it works as a protocol to aggregate data of decentralized social networks. If you want to check it out, the code of a sample application in its early stages is hosted at Google Code. The goal of NoseRub is that everyone can manage and/or host his/her own social network. By separating the profile, the network, and the data, everything will become portable to a great extent. You stay in control of your data, and if any of your friends update their data, these changes will automagically be incorporated into your app.
NoseRub was shown in public for the first time at BarCamp Cologne 2 (one of the most eagerly awaited sessions), where we could see the sample app on two local webservers. It was built around the CakePHP framework, so the structure of the code is very clearly laid out. Of course, because of its early status, many questions arose at the BarCamp session which need to be clarified and resolved (security concerns, technical specifiations). But all in all, the presentation left most of the participants in awe and/or enthusiasm. And so, like many others might already have done or will do within the next few days, I downloaded and installed NoseRub on my local server. What can I say, it works great even in its raw state. My guess is, that developers will improve it very quickly, add new services along the way, so that by the end of the year we should have a great application that helps us take over control over our social networks. Dirk published a quick tour of the sample app, check it out. I will certainly post more about NoseRub, so stay tuned.
