There is an active RDF4J community that uses the rdf4j-users Google group to communicate. You can browse through the group messages online without joining, but you’ll need to join the group to be able to post.
The RDF4J development team uses the firstname.lastname@example.org mailinglist to discuss development progress.
Internet Relay Chat (IRC) is a way to chat live with the RDF4J developers or other users. We use the
#rdf4j channel on
irc.freenode.net for discussion and help. You can use your favorite IRC app, or join us instantly via webchat instead.
#rdf4j channel is publicly logged:
If you think you’ve found a bug in RDF4J, or wish to log a request for a new feature or improvement, please use the RDF4J issue tracker. Before you add your new issue, though, please have a look around to see if it’s not already there.
