Sure. I think there's a risk that it will bump a little bit into what my colleague mentioned before about having acts written in a technologically neutral fashion. Metadata means one thing today; it could well mean a totally different thing in five or 10 years.
I do think that metadata has a very high privacy value. Its disclosure and its sharing can have very high risks associated with it. It can be extremely personal, and I think that it needs to be strongly protected.
