Often it is the same licence as the package, BSD or GPL. The debian/copyright file should tell you for each package. We only guarantee that the licence is free, and that it's compatible with the licence of the package itself (since the binary is a derivative work of the source and the packaging scripts) However, I'm not sure that the information you are extracting is covered under copyright. If it's not, then you are good to go. If not, then depending on interpretation, you may be creating a derivative work of them all, which effectively means you need to treat the whole as GPL, and omit any packages which have the packaging under a non-GPL-compatible (but free) licence. I don't know whether such exist. > 2.) What requirements would I have to meet to include this information on a > web site? Assuming for the moment that you are using copyrightable information and creating a derivative work, then you must satisfy the licence of all the source materials. This will resolve to distributing everything under the GPL and therefore providing the "preferred form of modification". > 3.)

First of all, databases are only debatably copyrightable; they have different statuses in different jurisdictions. Secondly, I am still not sure whether the metadata you are extracting is copyrightable. If it's not, you can do what you like. If it is, then you are almost certainly creating a derivative work, so you have to comply with the licences of your source material, many of which are GPL, which means you would have to use the GPL as well.
