We have released several of our software projects as free and open source software.

DeliciousAPI

This Python programming library provides an unofficial API for retrieving data from Yahoo!’s social bookmarking service Delicious.com. For instance, it allows to retrieve the full history of a website’s bookmarking history (the official API does not provide such a feature). Personally, we have used DeliciousAPI for automated distributed crawling runs on Hadoop clusters to create large-scale experimental data sets for our research work on the Social Web and collaborative tagging, most notably SPEAR.

You can follow and contribute to the development of DeliciousAPI at our GitHub repository. If you just want to download the reference implementation, you can quickly install it through easy_install DeliciousAPI (you might have to use sudo easy_install DeliciousAPI on systems such as Mac OS X or Ubuntu Linux).

Ever wanted to share files auto-magically with your neighborhood?  Forban is a free software and an epidemic protocol to share files in your local area network.  It is released as free software, and you are more than welcome to build other software implementations from it.

Forban is also the software basis for the sharing box, an autonomous hardware used to share files with friends, relatives and even with strangers.

SPEAR Reference Implementation

We provide a reference implementation of our SPEAR ranking algorithm as free and open source software, written in the Python programming language.

You can follow and contribute to its development at our GitHub repository. If you just want to download the reference implementation, you can quickly install it through easy_install Spear (you might have to use sudo easy_install Spear on systems such as Mac OS X or Ubuntu Linux).
