That was the first thing I picked out too. From wikipedia (I know..):
> Meta ... is a prefix used in English ... to indicate a concept which is an abstraction from another concept, used to complete or add to the latter.
How is the entire message content abstract to the entire message content? It seems like they've just added the prefix to get around some legal obligation. What the fuck.
It's a bit more nuanced than that. What they seem to be doing is looking at the contents for automated text messages such as missed call alerts or texts sent with international roaming, and using that to generate metadata such as call data or geo-location data, called 'content-derived metadata'. So it's generating new metadata records by analysing the content.
interesting definition of metacontent
