JHOVE Description

Provides functions to perform format-specific identification JHOVE provides functions to perform format-specific identification, validation, and characterization of digital objects. The set of characteristics reported by JHOVE about a digital object is known as the object's representation information, a concept introduced by the Open Archival Information System (OAIS) reference model . The standard representation information reported by JHOVE includes: file pathname or URI, last modification date, byte size, format, format version, MIME type, format profiles, and optionally, CRC32, MD5, and SHA-1 checksums . Additional media type-specific representation information is consistent with the NISO Z39.87 Data Dictionary designed for digital still images and the draft AES metadata standard for digital audio. What's New in This Release: · PDF MODULE · The PDF/A profile has been updated to the final version of 19005-1:2005(E) and made more thorough. Among the changes: · The set-state and no-op actions disqualify a PDF/A candidate. · The ASCIIHexDecode and ASCII85Decode filters no longer · disqualify a candidate. · Checking of outlines has been added. · Additional checking of Type 1 fonts and symbolic fonts. · Bug fix in checking type 2 subfonts. · An LZW filter in an image object disqualifies a candidate. · The xpacket processing instruction is checked for attributes · which disqualify from PDF/A. · Conformity to implementation limits is checked as a condition · of PDF/A conformity. · JPEG2000 MODULE · The pathological case of an image with no components is checked so · it won't cause a crash. · XML HANDLER · A reset() function has been added so that if the handler is reused, · it will return to a valid initial state.
