Can I include GPLv3 licensed documentation in a collection of GFDL licensed documents, or: what are the limits of an "Aggregate" in GFDLv1.3/GPLv3?

It is pretty clear that your website, which puts different manuals side by side (and does not merger the manuals into one larger document) is an aggregate. The GPL FAQ are pretty clear that what you ...

Can I sell Wiktionary data?

For simplicity's sake, let's assume that Wiktionary is licensed under CC-BY-SA 3.0, rather than also accounting for the GFDL dual-license. The CC-BY-SA license does not prevent you from selling the ...

Does changing the markup language of a document count as a "Modified Version" under the GFDL?

Generally, if it is not verbatim, it is a modification. That is especially true, if you are 'changing links' and cannot ensure that every single word remains unchanged. However, where is the issue ...

A non-bloated license for documentation with the benefits of GPL?
