An introduction to JHOVE

JHOVE provides functions to perform format-specific identification, validation, and characterization of digital objects.

Identification, validation, and characterization actions are frequently necessary during routine operation of digital repositories and for digital preservation activities. These actions are performed by modules. The output from JHOVE is controlled by output handlers. JHOVE uses an extensible plug-in architecture; it can be configured at the time of its invocation to include whatever specific format modules and output handlers that are desired. The initial release of JHOVE includes modules for arbitrary byte streams, ASCII and UTF-8 encoded text, GIF, JPEG2000, and JPEG, and TIFF images, AIFF and WAVE audio, PDF, HTML, and XML; and text and XML output handlers.
