The Expertiza project is software to create reusable learning objects through peer review. It also supports team projects, and the submission of almost any document type, including URLs and wiki pages.
Displays/manages exercise data like speed, time, heart rate etc. Import from Garmin "Forerunner"-devices and export of the track-data to Google Earth is possible as well.
This project is part of my Google Summer-of-Code project to create a KDE based sensor network programming interface using the Ruby programming language.
