EPUB 3 - Metadata Refines Chains (title-type, file-as, collection)
Two dc:title elements distinguished only by refines chains into title-type and display-seq, a creator with file-as and a MARC relator role, and a series declared with belongs-to-collection. The structure a catalogue actually needs, and the one flat metadata readers collapse into a single confused string.

Testing contract
Expected to pass- Scenario
- Extract the display title, the sort name, and the series position for a library listing.
- Expected result
- The main title and subtitle are distinguished by their title-type refines rather than by order, the author sorts under Brandt-Nakamura, and the book reports as position 4 of The Conformance Shelf.
What is a .epub file?
EPUB is the open e-book standard, a ZIP archive containing XHTML content documents, CSS, images, and a package manifest describing reading order and metadata. It supports reflowable text that adapts to screen size and is supported by most e-readers except Kindle natively. It is the dominant format for distributable e-books.
How to use this file
Use an example EPUB to test e-book parsing, ZIP-package and manifest handling, reading-order and metadata extraction, and rendering in e-reader applications.
How to use this file for testing
“EPUB 3 - Metadata Refines Chains (title-type, file-as, collection)” is a deterministic Novus Examples fixture for Metadata testing, Conversion testing. Images, audio, video, and documents with documented metadata paired with deliberately stripped versions, for verifying extraction, preservation, redaction, and privacy-scrubbing behavior.
Documented properties for this file: seed 20260807. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
E-book fixtures are structured archives documented down to their spine and manifest. Test readers and converters, and where a valid↔intentionally-invalid pair exists, assert graceful handling of the malformed container.

- epubEPUB 2.0.1 - Cover by meta name="cover" Only (no guide, no cover page)The cover convention that predates every standard way of doing it: a bare meta name="cover" pointing at a manifest id, with no guide reference, no cover XHTML page and nothing in the spine. For testing cover extraction against the messiest of the three EPUB 2 conventions.

For testing FB2 image extraction and the converters that have to turn that blob back into a real file.
