T1A: JHOVE2 – A Next-Generation Framework and Application for File Characterization

8:00am-3:15pm, May 16, 2011


JHOVE2 is an open source framework and application for the next generation format-aware characterization of digital objects.  Characterization is the process of deriving representation information about a formatted digital object that is indicative of its significant nature and useful for purposes of classification, analysis, and use in digital curation, preservation, and repository contexts. JHOVE2 builds on the success of the original JHOVE characterization tool by addressing known limitations and offering significant new functions, including: object-focused, rather than file-focused, characterization; signature-based file level identification using DROID; aggregate-level identification based on configurable file system naming conventions; rules-based assessment to support determinations of object acceptability in addition to validation conformity; and extensive user configuration options.  The 2011 release of JHOVE2 represents the availability of a significant new tool for digital preservation. This course provides a broad overview of JHOVE2, as well as detailed information on its functionality, architecture, use in local workflows, and open source community.



This course enables the attendee to:

·         Understand the role of file characterization, including identification, feature extraction, validation, and assessment, in digital curation and preservation workflows.

·         Appreciate the functionality of the JHOVE2 application, including the significant enhancements relative to JHOVE, and new capabilities based on object- and aggregate-level characterization.

·         Learn the architecture, componentry, design patterns and Java API’s of the JHOVE2 framework, as well as the configuration options for plug-in modules, characterization strategies and results formatting.

·         Demonstrate the use of JHOVE2’s new rule-based assessment capabilities, and integrating these into local workflows to determine object acceptability.

·         Gain a better understanding of the community framework for the project and how individual institutions can both contribute new format modules as well as resources to help extend and sustain the open source project.


Intended Audience

Technologists, developers, managers, analysts, and administrators engaged in digital curation, preservation, and repository activities whose work is dependent on an understanding of the format and pertinent characteristics of digital assets.
