[Digikam-users] Image Title MetaData

[Gilles Caulier]

Why digiKam & co do not handle Headline to set caption as well : look
IPTC tags description :

0x0069 	105 	Iptc.Application2.Headline 	String 	No 	No 	0 	256 	A
publishable entry providing a synopsis of the contents of the object
data.

0x0078 	120 	Iptc.Application2.Caption 	String 	No 	No 	0 	2000 	A
textual description of the object data.

...from http://www.exiv2.org/iptc.html

To resume, headline is limited to 256 char, where Caption is limited
to 2000 char !

Headline is a resume, not the right place to set a caption or full description.

Why Flickr (or picasaweb) use Headline as caption tag ? I don't know,
but i suspect that both don't understand properly what's the metadata
are delegate for.

In fact IPTC are deprecated since a long time and XMP must be used
instead, for a simple reason : IPTC do not support UTF8 and use only
ASCII. Also IPTC string size are limited. These problem do not exist
with XMP...

Now, look how digiKam set caption in image metadata :
