JHOVE 1.14 released

The latest version of JHOVE, the open source file format identification, validation and characterisation tool for digital preservation, is now available to download. Version 1.14 is the first official release since the Open Preservation Foundation took over stewardship of the tool in February 2015 to provide it with a permanent and sustainable home. A 1.12 beta was released in October 2015 which focussed on stabilisation of the code base and automated build, testing and deployment.

Version 1.14 has three new format modules: gzip, WARC and PNG.

Other improvements and highlights for this release include:


  • Ant build replaced with Maven with distribution through OPF Artefactory server;
  • modularised project structure with “fat jar” packaging;
  • Java 5 support;
  • Prototype Black Box Testing module
  • cross platform installer;
  • Travis CI build; and
  • Updated site pages
