Data sources and licenses

concert.fux is a non-commercial catalog of live music. It does not generate its own facts: every artist, event, venue, festival series, and image on this site is mirrored from a public source. This page lists those sources and the licenses that apply, so it's clear what you can reuse, and where corrections belong.

Artists, events, venues, festival series, and the relationships between them come from MusicBrainz, the community-maintained music encyclopedia. Editorial content (annotations, disambiguations, tags) is licensed under CC BY-NC-SA 3.0. Core factual data (names, dates, identifiers, relationships) is released into the public domain under CC0 1.0. Every entity page on concert.fux links back to its MusicBrainz source — corrections made there flow back here on the next ingest cycle.

Images are fetched on our server from three upstream sources and cached locally:

• Wikidata — artist, venue, and series photos linked from a Wikidata item's P18 (image) statement, served from Wikimedia Commons. Each Commons file carries its own license; click through to the Commons description page for the specific terms.
• Cover Art Archive — artist images contributed by the MusicBrainz community, licensed by the uploader (typically CC0 or CC-BY).
• Event Art Archive — event posters and flyers. Licenses are set per item by the uploader.

Map vector tiles, the map style, and glyph fonts are served by OpenFreeMap, a free hosted tile service operated independently of concert.fux. OpenFreeMap publishes its style and software under permissive open-source licenses.

Underlying map data (roads, place names, building footprints) is © OpenStreetMap contributors and is licensed under the ODbL. If you spot a wrong street, missing venue, or misnamed neighborhood on the map, fix it on OpenStreetMap — the change will appear here on the next tile rebuild.

Venue coordinates and city/area hierarchies come from MusicBrainz, which itself sources many of its place identifiers from OpenStreetMap and Wikidata. The same upstream licenses apply.

Because nothing on concert.fux is original, corrections need to land upstream to stick: edit the entity on MusicBrainz for facts and relationships, on Wikidata or Cover Art Archive for images, or on OpenStreetMap for map data. The next ingest run picks the change up automatically.
