Machine-readable files

llms.txt

/llms.txt is a plain-text summary of EHW for language models and agents. It covers what the site is, which pages to read, and how to open the map at a view.

Sitemaps

• /sitemap.xml lists the main pages and every documentation page.
• /sitemap-systems.xml lists the generated country, fault and supervolcano pages.

robots.txt

/robots.txt lets search engines and AI assistants read every public page. AI agents are kept out of the raw API under /api/, except for /api/v1/openapi.json, so an agent can learn what the API offers without polling it.

Structured data

The front page carries schema.org JSON-LD: the website with its search, the organisation, the web application, a breadcrumb and the FAQ. Each documentation page carries only its own breadcrumb.

Documentation pages

Every page under /docs is also served as plain HTML, with its full text and its own title and description. It can be read without running JavaScript.
