Validation Tool for EPUB

EpubCheck is a tool to validate IDPF EPUB files. It can detect many types of errors in EPUB. OCF container structure, OPF and OPS mark-up, and internal reference consistency are checked. EpubCheck can be run as a standalone command-line tool, installed as a Java server-side web application or used as a Java library.
