The word "interlinear" means "something between lines" or "something inserted between lines". It includes ruby, ken-dot, added kana (characters which represent the remaining of the pronunciation of Kanji), and return mark (a mark which indicates the reading order of Chinese ancient documents when Japanese are reading them) in Japanese documents.
Regarding properties of each interlinear object, we (CICC Font WG) made a presentation in MLIT (Multilingual Information Technology) meeting held in Hanoi, Vietnum in October 1998. We also brought the document to ISO SC34 meeting held in Chicago in November 1998 and they decided to go forward on this as a subdivision of the font project.
This time, we are proposing a generic model for interlinear object so that you can adopt it for its broad use in Asian countries other than Japan as well as Japan.
You can associate multiple interlinear objects with the same character(s).
This document doesn't provide any particular way to specify these items above. For example, you may use customized SGML/XML tags to do that.
Absolute or relative to font size of character(s) with which the interlinear object is associated.
Absolute or relative to font size of character(s) with which the interlinear object is associated.
This value is the offset between the tail edge in the virtual box of the first character with which interlinear object is associated and the tail edge in the virtual box of the first character of interlinear object.
When this property is specified, the property for position in writing direction will be ignored even if there is one.
Absolute or relative to font size of character(s) with which the interlinear object is associated.
This value is the offset between the baseline of character(s) with which interlinear object is associated and the baseline of interlinear object.
