I am Prashant Verma from IIT Roorkee, India. I was trying to setup the bookbrainz-site repository after cloning but for test database when I tried to download it the URL (https://bookbrainz.org/dumps/latest.tar.bz2) was not working.
An issue has been opened here: https://tickets.metabrainz.org/browse/BB-334
In the meantime, you can find the latest dump at https://bookbrainz.org/dumps/latest.sql.bz2
Also, please let me know that what should I have to fill in callback url field when requesting for clientID and clientSecret on https://musicbrainz.org/account/applications/register.
The callback url should be
http://localhost:9099/cb if you haven’t changed the default port 9099.
I invite you to come ask questions on our IRC channel #metabrainz, more apt to discussions
