Abstract
This document specifies and extends the "Robots Exclusion Protocol" method originally defined by Martijn Koster in 1994 for service owners to control how content served by their services may be accessed, if at all, by automatic clients known as crawlers. Specifically, it adds definition language for the protocol, instructions for handling errors, and instructions for caching.
For the definition of Status, see RFC 2026.
For the definition of Stream, see RFC 8729.
