Characterisation is comprised of four elements: first, identifying the object’s format; second, validating that the object conforms to its format’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. |
The software was designed to be able to integrate with other applications to enable easy incorporation into a repository’s Ingest workflow. | The software was designed to be able to integrate with other applications to enable easy incorporation into a repository’s Ingest workflow. | ||

JHOVE2 separates identification from validation, allowing the software to identify objects even if they are not valid. This also provides the opportunity to use the [http://www.dcc.ac.uk/resources/external/pronom PRONOM] 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. |
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. | 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.

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. 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. | 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.
