What &quot;data&quot; are you talking about that Lightroom stores in files? How is your &quot;data&quot; different than what is known as &quot;metadata&quot;?<p>If I tag a photo or picture, I want the metadata to go with me. I can create a dynamic playlist of photos on all my devices based on the metadata on multiple different platforms (even in my car). If I choose to strip my personal metadata later, it&#x27;s just a single click. What is idiotic is to store metadata only in silos (iTunes, Lightroom, iPhoto databases), it&#x27;s a vendor lock-in that will hurt the customer in the long term.
