Xeto is a data-only type system. The name is derived from the phrase "eXtensible Explicitly Typed Objects". Xeto defines a simple plain text format used to declare types and to exchange typed data. It is designed to build and validate Project Haystack data models. But Xeto is general purpose enough to use with any structured data including CSV, JSON, or SQL data.
