I would like to ask if there exists any online or downloadable descent dictionary of rhymes. I would prefer it to be structured and readable, so that I could eventually parse it. It is very important that it should not be a ready-to-use app like rifmovnik.ru
If there is no available free resource, then I would definitely ask you if it is legal to build my own dictionary based on extracts from internet libraries. I think this could be problematic because of the copyright.
