Its a good start but here above is already an example of the format. I also think a link to the source is important. It allows people to subscribe easier, it is a source to back up the data, and deals often change or have complex, small letters (AUP).

Before filling the database first need to think this through, at least, I prefer to first figure such out before contributing. And, I don't dare to add the data posted in the first post because I'm not the author, and I do miss several details.

Nevertheless, I've added the one I worked out (XS4All).
