How Metadata Was Formed

It's easy to find data on the source of "metadata": the word was formed by combining "data" with "meta-," which means "transcending" and is often used to describe a new but related discipline designed to deal critically with the original one. "Meta-" was first used in that way in "metaphysics" and has been extended to a number of other disciplines, giving us such words as "metapsychology" and "metamathematics." "Metadata" takes the "transcending" aspect a step further, applying it to the concept of pure information instead of a discipline. "Metadata" is a fairly new word (it appeared in the latter half of the 20th century), whereas "data" can be traced back to the middle of the 17th century.
