The question: For this image, what should be the values of each of
these tags? (The MWG tag descriptions are in brackets.)
- ModifyDate - ("modification date of the digital image file")
- CreateDate - ("creation date of the digital representation")
- DateTimeOriginal - ("creation date of the intellectual content being shown")
- DateTimeOriginal - I think it is fairly clear that this should be 2009/10/23, the date that the image was last modified.
- CreateDate - If we take the MWG description literally this should be 2009/09/12 (the date that the image was scanned), however this date is perhaps not as meaningful as some of the other possibilities.
- DateTimeOriginal - This one is up for grabs. Any of 2009/05/01, 2005 or 1941/12/07 could be possible.
I suppose the proper value for DateTimeOriginal depends on the context in which the image is used. If I want to associate the image with other pictures from my trip, then 2009/05/01 is the most appropriate date to use. However, if I am using it to document an essay on American history, then 1941/12/07 is more significant, or if used in a biography of Tom Freeman, 2005 is the appropriate date.
Confusing.
