Paul Hannan and Tony McGuckin from the IBM XPages development team have posted a new project to OpenNTF: Profiles application based on XPages.
You can run this application live.
See here to get a detailed description how this application was built.
The application itself is a profiles type application similar in many ways to a contacts list. It allows the user to create a new profile document, search for existing profiles aided by Ajax type ahead and view filtering, add ‘friends’ to their own profile, as well as many other features.
