For an in-depth description of this tool and its creation, we refer to the following paper:
Git2PROV: Exposing Version Control System Content as W3C PROV by Tom De Nies, Sara Magliacane, Ruben Verborgh, Sam Coppens, Paul Groth, Erik Mannens, and Rik Van de Walle Published in 2013 in the Poster and Demo Proceedings of the 12th International Semantic Web Conference.

We chose to make Git2PROV open source under GPL Version 3 license because we believe this will lead it to its full potential, and be of much more value to the Web community than a single isolated instance running on a server somewhere.
So in short, you are free to use and modify Git2PROV for non-commercial purposes, as long as you make your stuff open source as well and you properly credit us. This is most conveniently done by citing the paper mentioned above.
Make sure you have node.js and git installed and in the system PATH variable. Then, run:
[sudo] npm install -g git2prov
Converting a repository
To convert a single repository, run:
git2prov git_url [serialization]
git2prov firstname.lastname@example.org:RubenVerborgh/N3.js.git PROV-JSON
Running the server
To run the server, use the following command:
Then go to your browser and enter the following url: http://localhost:8905/
This will give you the standard Git2PROV homepage.
TO use the service directly, use the following URL: http://localhost:8905/git2prov?giturl=&serialization=&[optional parameters] The OPTIONAL parameters are:
- PROV-N (default)
- true ---> This will force the git log to use short hashes, making the output more readable by humans
- ---> This provenance relation will not appear in the output. Multiple values are possible.
To start a proxy server: node proxy.js for example: node proxy.js 80 8905
Running as a service on a Linux/UNIX machine
This script is used in combination with init.d. You could also modify it to work with upstart.
Copy the startup script "git2prov" to your /etc/init.d directory:
sudo cp scripts/git2prov /etc/init.d/git2prov
Make it executable
sudo chmod a+x /etc/init.d/git2prov
add it to the startup services
update-rc.d git2prov defaults
You can now do commands such as
sudo service git2prov start sudo service git2prov restart sudo service git2prov stop
And the service should automatically start when the machine is rebooted.
