I think that's maybe no news, but you talked about ^exiv$ in the past
and i just notice there's exiv2 now:
http://www.exiv2.org/
quote:
The Exiv2 library provides
* full read and write access to the Exif and IPTC metadata of an image through
Exiv2 keys and standard C++ iterators
* a smart IPTC implementation that does not affect data that programs like
Photoshop store in the same image segment
* Exif MakerNote support:
- MakerNote tags can be accessed just like any other Exif metadata
- a sophisticated write algorithm avoids corrupting the MakerNote:
1) the MakerNote is not re-located if possible at all, and
2) MakerNote Ifd offsets are re-calculated if the MakerNote needs to be moved
(for known Ifd MakerNotes)
* extract and delete methods for Exif thumbnails (both, JPEG and TIFF
thumbnails)
* set methods for Exif thumbnails (JPEG only, TIFF thumbnails can be set from
individual tags)
* complete API documentation (by Doxygen)
Exiv2 is also a command line utility to
* print the Exif metadata of JPEG, TIFF and several RAW image formats as
summary info, interpreted values, or the plain data for each tag (a sample is
here)
* print the IPTC metadata of JPEG images
*print, set and delete the JPEG comment of JPEG images
*set, add and delete Exif and IPTC metadata of JPEG images
*adjust the Exif timestamp (that's how it all started...)
*rename Exif image files according to the Exif timestamp
*extract, insert and delete Exif metadata, IPTC metadata and JPEG comments
*extract, insert and delete the thumbnail image embedded in the Exif metadata
*fix the Exif ISO setting of picture taken with Nikon cameras
