Working with Virtuoso

These are some notes for the future developers of LinkedMusic.

Community

• The open source support is great. If you have any problems, post your questions here: openlink/virtuoso-opensource.

Versions and compatibility

• There exists an enterprise version of Virtuoso; however, it does not seem to offer additional functionalities useful to the LinkedMusic project.
• There is a MusicBrainz Cartridge for Virtuoso. There is no documentation of it and it seems like it's deprecated, but it might be a possible direction to import MusicBrainz onto Virtuoso.

Quirks

• Documentations on their website might be outdated or incomplete. If you come into a road block, make sure to ask the developers on their GitHub.
• Virtuoso may also have deprecated add-ons and known, unpatched problems. Again, ask the developers.
• Make sure to assign roles to any new users, as role-less users can only log in via isql (command line).
