The YAML Specification is defined in this GitHub repository.
The YAML 1.2 Specification was last updated in 2009. Between 2001 and 2009 the YAML Creators planned to do much more with the language, such as defining YAML Schema and YAML Path specifications, but the team ran out of steam. Since then YAML usage has continued to grow to become a major component of modern computing. After a few false starts, the current Core Development Team came together starting in 2016, and started meeting weekly in Spring 2020. Work is now actively happening to move the YAML language forward to meet the needs that have become evident over the past 10+ years.
This wiki is being used to clarify various YAML specification topics. Many of these topics belong in the repository itself, but it is faster and easier to put information here first until the topics are fully vetted and finalized.
That is to say, anything presented here is SUBJECT TO CHANGE. That said, the content is written to be as helpful as possible with what we know today.
Current topics are:
- The YAML Community
- The YAML RFC Process
- The YAML 1.2.1 Specification
- The YAML 1.3 Specification
- Contributing to the YAML Specification
- The YAML Language Core Development Team
- Current YAML Websites
