# Urban Art Core > Street art and graffiti reporting from 2009–2012: artist interviews, galleries and photo essays from Berlin to Bristol and beyond. 1113 posts, published 2009–2026, written by Jan Brennenstuhl. Every post is available as HTML at its URL, and as JSON (`index.json`) and Markdown (`index.md`) by appending the file name to the post URL, for example https://www.urbanartcore.com/see-no-evil-bristol-final-walls/index.md. Pages advertise these with ``. Each post page also links to related posts (with the reason they are related), its place in each artist's or event's chronology, and the collections that include it.
