</div></div>I tried that. E.g., if I extract the metadata using<br>
exiv2 ex IMG_0910.JPG<br>
then I get a bunch of complicated stuff including:<br>
<br>
<rdf:li xml:lang="x-default">This is a picture of a person</rdf:li> <br>
<exif:UserComment> <rdf:Alt> <rdf:li xml:lang="x-default">This is a<br>
picture of a person</rdf:li> </rdf:Alt> </exif:UserComment><br>
<dc:description> <rdf:Alt> <rdf:li xml:lang="x-default">This is a<br>
picture of a person</rdf:li> </rdf:Alt> </dc:description><br>
<br>
So it seems that the caption has been placed in multiple tags, and I<br>
don't know how to write to those tags.<br>
