EPUBCheck Development Update
EPUBCheck plays a significant role within the ebook production process, checking EPUB files against the specification to ensure they validate. As the EPUB specification has evolved over time it is important that the tools we use to create and validate EPUB files are kept up to date. Many retailers require EPUB files to have been validated by EPUBCheck. However, in its current state, EPUBCheck cannot properly validate many EPUBs that meet the most up to date standards.
To address this the Publishing Business Group at W3C put out a request for proposals to update EPUBCheck, and following a competitive selection process the DAISY Consortium has been selected to perform the update to:
- Bring EPUBCheck in sync with the dynamically evolving core web specs of HTML, CSS, and SVG and also with the current version of EPUB 3
- Fully support the EPUB Accessibility Guidelines, making sure that your products are usable for everyone
- Add new features, such as HTML validation (in coordination with the W3C validation services) and a better check of media overlays
- Offer better service to the publishing industry with a faster response to bug reports and feature request.
This work is being funded through donations from organizations which use the EPUBCheck tool, and while there are different sponsorship levels, any amount of donation is welcome to help support this effort to update and overhaul EPUBCheck. Full details are available at the Publishing@W3C fundraising page.
We look forward to bringing you updates as this exciting work evolves.
