 [https://bitbucket.org/jhove2/main/wiki/Home JHOVE2] is a follow-on to the Harvard/JSTOR [[JHOVE (Harvard Object Validation Environment)| JHOVE]] project, with the similar purpose of allowing data curators to characterise the digital objects in their repositories. &nbsp;Characterisation is comprised of four elements: first, identifying the object&rsquo;s format; second, validating that the object conforms to its format&rsquo;s technical norms; third, extracting technical metadata from the object; and fourth, assessing whether the object should be accepted into a repository, based on policies set by the curator. &nbsp;

 ====Usability====
 JHOVE2 does not include a GUI, which will be challenging for many users.
 ====Expertise required====
 Installation requires solid knowledge of command line interfaces and experience with manually editing configuration files. Creation of the assessment policies requires detailed knowledge of digital preservation standards and technologies. &nbsp;

 ====Functional notes====
-The JHOVE2 project came about as a response to perceived shortcomings in the [http://www.dcc.ac.uk/resources/external/jhove JHOVE] software. JHOVE2 separates identification from validation, allowing the software to identify objects even if they are not valid. &nbsp;This also provides the opportunity to use the [http://www.dcc.ac.uk/resources/external/pronom PRONOM]&nbsp;registry in signature-based identification via integration with [http://www.dcc.ac.uk/resource/external/droid DROID], creating the ability to identify many more format-types than those for which it has validation modules. Other improvements include the ability to characterize hierarchical digital objects such as directories, zip files and bit streams nested within files, and a design that allows easier integration with other applications.

Other improvements include the ability to characterize hierarchical digital objects such as directories, zip files and bit streams nested within files, and a design that allows easier integration with other applications.
 JHOVE2 has validation modules for the following format types: ICC color profile; SGML; Shapefile; TIFF (including TIFF/EP, TIFF-FX, TIFF/IT, Exif, GeoTIFF, DNG and RFC 1314); UTF-8 encoded text; WAVE (including Broadcast Wave); XML; ZIP; GZIP; ARC; WARC; and arbitrary bytestreams, filesets and directories. Modules for JPEG 2000 (JP2 and JPX profiles) and PDF (including PDF/X and PDF/A) were planned but have not been implemented yet. &nbsp;
 For comparison, ICC, SGML, Shapefile, ZIP, GZIP, ARC and WARC are newly supported in JHOVE2; however, JHOVE supports AIFF, GIF, JPEG, JPEG2000 and PDF while JHOVE2 does not. &nbsp;HTML is also not supported in JHOVE2, as it is in JHOVE, but since HTML can be expressed in terms of SGML or XML the functionality remains the same.&nbsp;

-JHOVE2 is open source software for format-aware characterization of digital objects. JHOVE2 analyzes digital objects with these questions: ===
+====Provider====
+California Digital Library, Portico, and Stanford University, with funding from the National Digital Information Infrastructure and Preservation Program (NDIIPP). Version 2.1 also credits the Bibliothèque nationale de France and Netarkivet.
-* What is it? (Identification) ===
+====Licensing and cost====
+Open Source [http://www.linfo.org/bsdlicense.html BSD license] &ndash; free.
-* What about it? (Feature extraction) ===
+====Development activity====
+JHOVE2 version 2.1 was released in March 2013.
-* What is it, really? (Validation) ===
+Funding for the JHOVE2 project ended in 2011. The project partners committed to providing self-funded maintenance (but not further development effort) for three years. Their goal was to create an open-source community to guide and foster JHOVE2 technical development, and the involvement of Bibliothèque nationale de France and Netarkivet from version 2.1 signifies some success in this regard.
+====Platform and interoperability====
-* So what? (Assessment)
+JHOVE2 is written in Java Standard Edition 6, and requires a Java 6 runtime environment. &nbsp;If the user is hoping to use the SGML validation module, an OpenSP SGML parser is required.
+Developers wishing to rebuild JHOVE2 from the provided source will need a full Java SE 6 development kit and the Apache Maven project tool.
