Release notes for JHOVE 1.0, 2005-05-26

1 General

1. Zero length files are now handled properly in all modules.

2. Missing start time in audio files is now handled properly in all audio modules.

3. Miscellaneous bug fixes, enhancements, and documentation updates.

2 AIFF Module

1. Corrected error causing BitrateReduction to be incorrectly reported for uncompressed PCM audio.

3 JPEG2000 Module

1. The module now validates the enumerated ICC profile types in the Color Specification Box. In the JP2 profile, an unrecognized ICC profile type marks the file as not well formed; in the JPX, the file is merely not valid.

2. In the beta 3 release certain invalid JPEG 2000 files were reported as well formed in the JP2 profile. This has been corrected.

4 PDF Module

1. Following the practice of Acrobat, the PDF module will accept the "%PDF-1.n" header comment anywhere in the first 1024 bytes of a file (with appropriate notification via an information message), rather than requiring that it start at byte offset 0.

2. The requirements for the PDF/A profile have been brought into conformance with the most recent version of the PDF/A specification, ISO/DIS 19005-1 of 2004-12-22.

3. Corrected bug that prevented valid PDF/X-1 files from being recognized as such.

5 TIFF Module

1. Files containing the EXIF GainControl tag (41991) will be inproperly classified as not well formed. The module is incorrectly assuming that the tag is a RATIONAL value, when it is in fact a SHORT.

6 WAVE Module

1. Corrected error causing BitrateReduction to be incorrectly reported for uncompressed PCM audio.

7 XML Handler

1. Dates reported for the NISO Z39.87 <mix:DateTimeCreated> element are now canonicalized to be in proper ISO 8601 form.

2. The NISO Z39.87 <mix:ScannerManufacturer> element is now reported, if known.

8 Audit Handler

1. The current working directory is reported as the "home" attribute of the <audit> element and individual files are reported as relative pathnames
