Description

Hi,

I'm not 100% sure this is a bug:

I have a lot of pictures that use Xmp.fwl.LocalCaption as the main description.

I can see the key when I do a 'exiv2 -PX $picture'

Xmp.fwl.LocalCaption                         XmpText   239 blablahblah lot of text here 

but trying to change it:


# exiv2 -ix -M "set Xmp.fwl.LocalCaption XmpText blahblah" A_S_9686.JPG 
-M option 1: Invalid key `Xmp.fwl.LocalCaption'
exiv2: Error parsing -M option arguments
Usage: exiv2 [ options ] [ action ] file ...

Manipulate the Exif metadata of images.

# exiv2 -ix -M "set Xmp.fwl.LocalCaption blahblah" A_S_9686.JPG 
-M option 1: Invalid key `Xmp.fwl.LocalCaption'
exiv2: Error parsing -M option arguments
Usage: exiv2 [ options ] [ action ] file ...

Manipulate the Exif metadata of images.

is not working. Am I missing something or did I hit a bug?

Btw. There are other keys in the Xmp.fwl "class".

If you want to have the picture for further investigation just write me an email :)

Here the exiv2 version and stuff:

# exiv2 -V
exiv2 0.20

Exiv2 doesn't know the fwl prefix. You need to register it. Something like this works:

exiv2 -M"reg fwl some-namespace" -M"set Xmp.fwl.LocalCaption blahblah" image.jpg

Where some-namespace should be replaced with the proper namespace URI for fwl.

If you know that URI, good. If not, you can trick exiv2 into showing it by running the above command (with "some-namespace") on a copy of an existing image that already has fwl properties and you'll get a warning of the form

Warning: Updating namespace URI for fwl from http://the.real.uri/ to some-namespace/

(maybe you'll need a newer version of exiv2 for that than 0.20, that warning was introduced relatively recently IIRC)

I'm going to set the status of this to "Resolved". Google can help me find the definition of the fwl namespace. In fact, this bug report is the first item that Google lists! I've confirmed that Andreas suggestion is totally correct:

$ exiv2 -M"reg fwl http://exiv2.org/issue783" -M"set Xmp.fwl.LocalCaption XmpText blahblah" jpg.jpg 
Warning: Updating namespace URI for fwl from http://clanmils.com/ to http://exiv2.org/issue783/
