in an short discussion with a colleague I he pointed out that there might be a 
legal problem for me, if we put the code on a github that does not belong to 
Apache. That’s because I had to make a request to be allowed to contribute to 
an open source project. The request I made stated that I would like to 
contribute to Olingo and that what I am allowed to do.
So I would be lucky if you create a repository within the Apache github.
