EpubCheck
Description
EpubCheck is a tool to validate EPUB files. It is also able to extract technical characteristics and embedded metadata from an EPUB file. Both the EPUB 2 and EPUB 3 formats are supported. 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 or used as a Java library. Development of this tool is supported by the International Digital Publishing Forum (IDPF), which also publishes the EPUB standards. Most of the EpubCheck functionality comes from the schema validation tool Jing and schemas that were developed by IDPF and DAISY. Initial EpubCheck development was largely done at Adobe Systems.
