eventually. i consider the dtd to be the crucial thing before i call
anything my plug-in writes "xml"

it is the nature of xml (at least for some of us) to be used to define
information in a way that meets your own needs. at least, this is
always what i thought was neat about it. of course, such flexibility
leads to ideas like this.

driving me is the frustrating situation in which many of the existing
options do not work on my operating system, or change so they dont work.
if i am going to put the time into this, i am going to end up with
information that i can share and information i can count on not changing
too often and information that i can trust.

as i said earlier, my app works on so many operating systems. i am
gathering information that other plug-ins i have written can use (i have
some really simple gallery scripts). just as the the photoshop plug-in
writes XMP for adobe, my plug-in will be writing GIPP for gimp. there
is a chance that there will be a user base of only one person. it is
being written to help me and some of my friends with their image
licensing problems.

you can clearly see how lazy i am. i dont want to have to paste
information or load a template even. one toggle and its off ....

GIPP will be a text xml file, so it could be useful to many.

we have had problems with exif containing inaccurate rotation
information already. XMP is as useful to gimp as GIPP is to photoshop.
i have never heard of IPTC. it will be useful to gimp users to get the
exif information and fix it if some other application wrote incorrect
information to it.

what is the big deal about using xml then?

the first big selling feature i responded to when xml first hit all of
my media was "flexibility". XMP is handled by an application which does
not work on my operating system and this is one of those inoperability
issues that i did not have too much to do with.
