Origami gives publishers a way to ship a richer scholarly product while remaining EPUB. The same file can degrade to ordinary reading in a plain EPUB reader while exposing much richer semantics, interaction, citation, AI, spatial, validation, and preservation capabilities in aware systems.
• A richer publication product without abandoning EPUB.
• Continued use of standard EPUB packaging and distribution.
• Compatibility with ordinary EPUB readers.
• No separate proprietary interactive edition is necessarily required.
• Rich semantics and interactions can travel inside the same publication.
• Explicit profile conformance.
• Machine validation beyond ordinary EPUB validation.
• Broken publications can be caught before release.
• Stable work, publication, artifact, and element identity.
• Version relationships between releases.
• Correction and errata infrastructure.
• Retraction and replacement infrastructure.
• Content-addressable scholarly services.
• Deep links to exact paragraphs, figures, equations, or definitions.
• Better citation-resolution services.
• Better discovery services using concepts, headings, references, relationships, and layouts.
• Better library integration.
• Publication-level knowledge graphs.
• Robust metadata exchange.
• Self-identifying extracted metadata records.
• Filename-independent metadata discovery.
• Machine-readable bibliography bundled with the title.
• Human-readable metadata backup through the Visual-Meta colophon.
• A print-to-digital bridge through visible self-description and self-citation.
• AI-ingestion readiness.
• Reduced hallucination surface through publisher-supplied semantics.
• Publisher-controlled authored views.
• Integrated interactive supplemental material.
• 3D objects and computational tables as part of the publication rather than loose attachments.
• Preservation of source relationships for reduced spatial assets.
• Extensibility without breaking old readers.
• Independent ecosystem potential.
• Reduced vendor lock-in.
• A market for competing enhanced reading systems over the same publication.
• Interoperable post-publication services for annotations, teaching, AI, citations, XR, and archives.
• One package can preserve both rich machine semantics and conventional human-readable content.
• The citation graph can be derived from publication-carried relationships rather than requiring all relationships to be reconstructed by a separate indexing pipeline.
• Origami can complement rather than replace an existing PDF-of-record workflow: the EPUB can provide liquid, semantic, and interactive reading while the PDF remains available as a fixed-layout rendition.
• Publisher search or digital-library results can deep-link to matching passages rather than only to document landing pages.
• A publisher can host a Web reader without changing the publication format, allowing rich reading without a proprietary desktop application.
• Publisher-hosted annotation or commentary layers can sit outside the immutable publication.
• Proceedings or journal issues can become queryable corpora on publication day because concepts, references, structure, and addresses are already carried by the papers.
• Shared stable addresses make privacy-respecting aggregate usage signals possible in principle without requiring the publication itself to contain personal reading state.
