Re: jena-csv
Not knowing that Jena-csv existed, I developed an extension to Any23, adding features for CSV.

Re: jena-csv
May I add: https://github.com/AtomGraph/CSV2RDF It's not that feature rich (supports minimal mode only), but has already proved to be pretty scalable.

As far as I know Docker container is a linux-only technology as it uses the cgroup feature of linux kernel. Docker on Windows uses VirtualBox to first emulate linux kernel and then run containers on it. So I dont think non-linux should be a concern. For database storage, we can probably have a convention that inside container, /mnt/tdb/ is where all databases are stored. If anyone wants to attach db from host they can do so with docker run -v /host/db/path:/mnt/tdb/ jena/fuseki Regards Siddhesh Rane
