Standardisation body
The ruby markup model currently described in the HTML specification is limited in its support for a number of features, notably jukugo and double-sided ruby, as well as inline ruby. This specification addresses these issues by introducing new elements and changing the ruby processing model. Specific care has been taken to ensure that authoring remains as simple as possible.
This document was largely developed to address the shortcomings listed in Use Cases & Exploratory Approaches for Ruby Markup. [ruby-use-cases]
