Yes, that is what I mean. E.g. the TIGER corpus requires clicking through some pages and forms to reach a download page, but in principle, it appears as if the corpus was simply downloadable by a deep-link URL. The license terms state, that the corpus must not be redistributed. Some tools are also publicly accessible and downloadable but not redistributable. For example anybody can download TreeTagger and its models, but only from the original homepage. It is not permitted to redistribute it, i.e. to publish it to a repository or offer it on an alternative homepage. So there is a (small) class of resources between being redistributable and proprietary (for fee), namely being in principle publicly accessible (for free) but not redistributable. Cheers, -- Richard
