AISO is the technical layer that makes a site accessible and intelligible to search and extraction systems: complete HTML, crawler rules, structured data, content maps, and stable URLs. It is hygiene, not guaranteed citation.
Scope reviews known crawler access under the owner's policy, SSR or prerendering, JSON-LD, RSS, internal links, and optional llms.txt. Acceptance requires public text to be extractable without complex client code, robots rules to support the chosen policy, valid schema matching the page, and maps updating with content. Private data is never opened automatically.
