[OSGeo-Standards] Standard For Photo Descriptions?

[Landon Blake]

Raj,

I was hoping to have some sort of text file that could be edited by
users without special software. I don't think this would be possible
with EXIF.

Thanks for the suggestion.

Some of what you want is in the EXIF spec:
http://www.exif.org/specifications.html

Could you use their UserComment field for the rest? Obviously not  
optimal, but it would build on a standard, and people and software are  
already conditioned to look for photo metadata in the EXIF data.
