![](paris_extended_xmp.jpg)

License: [same as libavif](https://github.com/AOMediaCodec/libavif/blob/main/LICENSE)

Source: Metadata was extracted from `paris_exif_xmp_icc.jpg` with
`exiftool -tagsfromfile paris_exif_xmp_icc.jpg paris_exif_xmp_icc.xmp`. The text of the first book of
[De finibus bonorum et malorum](https://en.wikipedia.org/wiki/De_finibus_bonorum_et_malorum) was manually inserted in
that file under the tag `xmp:Label` and the second book under the tag `xmp:Nickname` (any `<` or `>` removed to avoid
conflicts with XMP). The file was reconstructed with
`exiftool -tagsfromfile paris_exif_xmp_icc.xmp -Exif= -icc_profile= paris_exif_xmp_icc.jpg -o paris_extended_xmp.jpg`.
The goal is to have a large XMP blob so that it can only be stored as multiple extended XMP chunks.
