DOKK is a community project aimed at combining information from free knowledge graphs and organizing it into meaningful topics.

It is developed as an activity of the Peers Community, and if you would like to help too you can get in touch with us on Freenode at #peers, ask a question on freepost, or write to zplus@peers.community, contact@peers.community.

At the moment the project is still in a early phase of development, which means a lot of information for topics could be missing and the website could be unstable.


This is a list of graphs from which we extract all the information used to build the topics.
