The Origami Text format could be like this in use:
Reading as EPUB
You can open it up in any EPUB reader (Calibre, Apple Books, Thorium Reader, Moon+ Reader, Sumatra PDF etc.) and read as you would any other PUB since Origami is a simplified EPUB without platform specific additions. You can change fonts, font sizes, themes and so on without problems.
Reading as Origami Text
Open it with a reader which also understands the Origami additions and you have useful further controls:
Copy Text to Cite
You can copy text, paste it into a word processor as a citation.
Reading Citation
When exported, and the person reads your document they can click on the citation and if they own the document you cite they can click on the title to open it to the section you are citing.
Follow Citations
You can view the citations as full knowledge objects (since they are stored as proper data not only basic surface text) to see them on a timeline, citation trees and more.
Spatial Experience
When someone opens the document in a spatial environment, all the positioning information is available for use. The mapped knowledge can be reconstituted in space.
AI Reading
Any AI can also read the full Origami Text including all the metadata (references with high resolution addressability, maths, glossary, spatial layout etc.) with no problem since it is presented openly and clearly.
Authoring Origami Text
User exports to EPUB with a word processor which understands the Origami Text rules, that’s it. The user will generally not even know that such a thing as Origami Text exists, just that “EPUB seems more compatible now”.
