So I just finished what I wanted to do quite some time ago. I created a PHP script aiding you in the fantastic task of inserting Oolite's entire solar system information (planetinfo.plist) into a MySQL database of your choosing.
I'm sure this opens the door to quite some interesting 3rd party web-based tool creation possibilities.
Here it is:
The repo contains the current planetinfo.plist as well as a .sql file of the finished result.
Obviously open-sourced. Enjoy!
I know the script is not perfect, but probably a good starting point. The defaults are - database: oolite_data, table: oolite_maps
