XARG (188455) writes "I am one of the admins maintaining collaboration based SF books catalog,
something like ISFDB.org but in Russian language, it is called Fantlab.ru.
We have an internal discussion now about which licence do we want to apply to ensure that the database of the website will:
1. Always stay open
2. Never be lost
3. The project can always be resumed forked on another domain in case of some internal disagreements.
We found that only if the website owners will always provide access to bulk download of the database this requirements will be fulfilled. Right now the access is free, but it is impossible to download the full database (it will require download of full website, parsing and reconstraction of the databse links). This is of course not feasible in a periodic way.
To our dissapointment we found no licence (not even CC and GNU that wiki uses) that ensures that access to BULK download of database must be provided in order to obey it. All licences talk about giving free access to data, but not about bulk download or periodic dumps of database.
Did I missed something or is it indeed in the grey area?
Right now there is no licence only short notice that "use of the web materials allowed only with attribution to the source"."
