We've put together a very rough roadmap for this project:
Launch the ListenBrainz beta in July 2017
Observe for possible problems and fix them as they come up.
Push the beta into full production as soon as all show-stopper (data loss) bugs are fixed.
Make our Google Big Query copy of the ListenBrainz data available to the public. This data repository will
be updated in real time with hopefully only a few seconds of latency.
As part of a Google Summer of Code project, we're going to add statistics and graphs for users, artists and lots more.
This will be released a the end of summer 2017.
Data export: To export our data on a regular basis so that others can use it.
We have not worked out many long term plans yet. Clearly we are on the road to developing
open source music recommendation engines, but that is still a ways off in the future.
