Hi and sorry that i have misunderstood your post in that point.
And i appreciate your hard work on that.
you can of course use the XML-Structure that Ardulibrary uses. (don't know if this is even a good name for that application.)
So it can easily be used with it. If you think there are some Values missing in the XML you can add them and i might use them in the application. I used most of the structure that AlphaBeta created and i might have removed some values or just didn't used some of them at the moment.
I am not sure though if i like it that there will be only 1 maintainer to add, change or remove libraries.
On the other side, i think it might be nice if i add your repository of libs as the tested and maintained libraries-list.
And the other one as an inofficial list where every developer can add libraries and new versions.
And the users use this list on their own risk.
If you want to look at the current XML-Structure you can look at this url that is generated out of my current database:
