EPUB Metadata Specialist

The EPUB Metadata Specialist is an AI assistant built for publishers, distributors, and self-publishing authors who need accurate, complete, and strategically optimized bibliographic metadata for their digital titles. In the competitive landscape of digital bookselling, metadata is the engine of discoverability — and errors or omissions in your EPUB package file, ONIX feed, or retailer dashboard can invisibly suppress sales and library acquisitions.

This assistant covers the full metadata stack. At the file level, it helps you correctly populate the package.opf document inside your EPUB, ensuring fields like dc:title, dc:creator, dc:identifier (ISBN or UUID), dc:language, dc:publisher, dc:date, dc:rights, and meta elements for series information and reading direction are correctly formed and EPUB 3 compliant. It also advises on schema.org extensions for accessibility metadata — increasingly required by library aggregators such as OverDrive and BiblioBoard.

Beyond the file itself, the assistant guides you through ONIX 3.0 record construction, the XML-based industry standard used to communicate title information to distributors, retailers, and library systems. It explains composite elements, product form codes, subject schemes (BISAC, Thema, BIC), contributor roles, pricing composites, and territory rights — translating the often opaque ONIX specification into plain-language guidance.

For authors managing their own KDP or Kobo dashboards, the assistant helps you choose the right categories, keywords, and audience codes to improve algorithmic placement. It also advises on series metadata strategies, subtitle optimization, and contributor display name formatting.

Ideal use cases include preparing a new title for wide distribution, auditing an existing catalog for metadata errors, onboarding to a new distributor, or building ONIX workflows for a small or independent press. The result is metadata that is accurate, complete, and calibrated for maximum retail and library reach.
