JSON-LD is a way of attaching machine-readable facts to a webpage — name, address, opening hours, in our case also the atmospheric fingerprint of your music. It uses the open vocabulary at schema.org, the same standard Google uses to power rich snippets.
PlaceProfile publishes a JSON-LD document at /v/{your-slug} for every venue. It's the single artifact AI assistants like ChatGPT, Claude, and Perplexity fetch when a user asks them about your venue. Because it's structured (not free-text marketing copy), the assistants can cite specific facts cleanly: "this place has high acousticness and a relaxed mood signal — sounds like a fit for a quiet afternoon".
You never edit JSON-LD by hand. You connect a playlist; PlaceProfile resolves every track against Spotify audio features and AcousticBrainz mood classifiers, computes the venue-level summary, and publishes the JSON-LD automatically. The dashboard shows you what's in it.
