JHOVE

JHOVE is a software package for the identification, validation, and characterization of digital objects. Its primary purpose is to support digital preservation by ensuring the integrity and understandability of digital files over time. JHOVE was originally developed by the Harvard University Library and is now maintained by the Open Preservation Foundation.

The software works by using format-specific modules to analyze digital files. Each module is designed to recognize and process a particular file format, such as PDF, JPEG, or TIFF. When JHOVE processes a file, it first attempts to identify the format and then applies the relevant module to check for structural validity and extract significant metadata. This metadata can include technical details, creation dates, and other information that helps in understanding and preserving the digital object.

JHOVE is particularly useful for libraries, archives, and other institutions that are responsible for long-term digital preservation. By using JHOVE, these organizations can proactively identify potential risks associated with their digital collections, such as corrupt files or obsolete formats. The tool helps to ensure that digital objects can be reliably accessed and used in the future, contributing to the preservation of cultural heritage and information. It is often integrated into larger digital preservation systems.
