FLOSS Metrics stands for Free/Libre Open Source Software Metrics. It is an European project targeted at free/open source software measurement.
The main objective of FLOSSMETRICS is to construct, publish and analyse a large scale database with information and metrics about libre software development coming from several thousands of software projects, using existing methodologies, and tools already developed.
 FLOSS Mole
FLOSSmole aims to:
- provide raw data about open source projects,
- provide summary reports about open source projects,
- integrate donated data from other research teams,
- provide some tools so that you can gather your own data.
Data dumps can be downloaded from Google Code.
Direct Database access is available.
Melquiades is the front-end interface for the FLOSS metrics european project.
The project also offers an API to access data.
