Dear Pierre-Antoine,

I asked the same question to me yesterday.

The spec says:

xmp:MetadataDate: The date and time that any metadata for this resource
was last changed. It should be the same as or more recent than

xmpDM:metadataModDate: The date and time when the metadata was last

I actually can not spot the exact difference. So either Adobe had a
reason why similar properties are defined in the Basic and the DM schema
and they just did not make the difference more explicit (which I
suppose) . Or it is redundant in the XMP Schema.

What do  others think?
