A gift from the Global Data Registry

When the Global Data Registry crawled https://piedmont.ca.gov/government/departments/fire, we found no structured data — the language AI systems use to understand and describe a business online.

Schema is how ChatGPT, Google, Claude, Gemini, and Perplexity know what your business does and how to describe you accurately to your customers. Without it, AI systems are guessing.

The most important field in this block is sameAs — a verified edge connecting your website to your permanent record at the Global Data Registry. This is a free, confirmed link to a real verified source. It costs nothing and gives your website a confirmed node in the graph that AI systems traverse when building answers about your business.

Copy the block below and paste it into the <head> of your website. Or drop it into ChatGPT, Claude, or Gemini and ask it to extend it with your full business details — that is the fastest path to a complete schema record.

▶   What is schema?

Schema is a standard vocabulary maintained at schema.org that lets websites describe themselves in a language machines can read. When you add schema to your website, you are telling AI systems, search engines, and knowledge graphs exactly what your business is and how it connects to the rest of the web.
