It used to be that information (Latinate) was called data
(Latinate), and everyone was happy. Then, a rash programmer
noticed that some data is about other data, and started calling
it metadata (Greekoid). The attraction was too much; gradually
it was realized that all data is about something, and that
that something can be de-reified as data. Today, nearly all
computer-stored information is in danger of being termed metadata.
To forestall further breakdown of the Englishistic language,
we need a sexy new source to borrow words from. I suggest cats,
because everyone will want to invent the word “mrowdata”, but
no one will want to say it.
