I can only see metadata, XMP specifically, becoming more important if
this new “Cloud Rule” begins to take hold with customers.
Google’s Data Liberation Front springs from customer
altruism but it also builds pressure in the industry to provide data
portability with cloud based services. For the customer, it removes
the ‘icky’ from the stickyness of web based services, for the service
providers it removes an excuse for not keeping their services
Yet to be seen if this will put pressure on services like Facebook and
Picassa to allow them to export them images with socially added tags
embedded in the images.
Last I checked none of the description, keywords or ratings I added
online at Photoshop.com were preserved in the photo I downloaded.
