History Instance

[old_sage]

What are history instances particularly when they are date stamped prior to the document's create date?  Does this mean that the current document is a derivative of an earlier document identified in the history instances? 

Is there a maximum number of history instances such that all of the history instances are not displayed in ExifTool?

What are history instances particularly when they are date stamped prior to the document's create date?  Does this mean that the current document is a derivative of an earlier document identified in the history instances? 

I can't answer this, but you might have more luck asking this in a forum for the software that writes this metadata.

Is there a maximum number of history instances such that all of the history instances are not displayed in ExifTool?

No.
