Good day all,
Can anyone help me with editing XMP metadata in image files (JPEG)?
I've searched the archives and I've found some messages about EXIF
data and IPTC metadata. But it looks like no one has done XMP
reading / editing yet. It wouldn't perhaps be too difficult, since
XMP data is 'just' an XML tree put somewhere into the JPEG binary
data. But I have no knowledge of binary data, so I can't figure out
how to add these metadata to a (JPEG) file.
Another option might be Image Magick. If an external could be built
around the Image Magick libraries, that would provide another way to
read and edit XMP data.
I need this facility for a new application we are going to build for
a couple of local cultural institutions. We need to describe lots of
historical photographs, and it looks like the best way to store these
descriptions is as metadata inside the files. These images are also
to be used in educational applications, where children can read - and
eventually edit - the metadata.
There will be a budget to develop this kind of thing. So what I would
like to know is:
- who feels able to develop this?
- how would you build this kind of functionality
- an estimation of the costs
You can contact me off list.
