I generally agree that Metadata does not fall under copyright, with these aspects. But it is more nuanced.. the Geotag, for instance: It was the photographers choice to move to this location, as it was the photoraphers choice to trigger the shutter at exactly that date_taken_time, as it was his/her decision to upload at specificly that upload_time. All of these aspects reflect individual choices, and individual choices are a reflection of our identity and creativity (ask Susan Sontag).
