JHOVE 1.22 released

The Open Preservation Foundation (OPF) is pleased to announce that the production version of JHOVE 1.22 is now available to download.

JHOVE is an open source file format identification, validation and characterisation tool for digital preservation, and part of the OPF reference toolset.

The major new features of this release are the addition of error IDs and the separation of modules from the installation. There are now permanent and unique IDs for all JHOVE error and information messages. This means error catching need no longer be done by string matching.

The modules are now individually versioned and packaged so users can now select, keep and update modules as they choose. This has meant making changes to every one of JHOVE’s main modules.
