From Wikipedia, the free encyclopedia.
In epistemology the prefix meta- is used to mean about. For example, metadata is data about data (who has produced it, when, what format the data is in and so on). Similarily, meta-memory in psychology means an individual's intuition about whether or not she would remember something if she concentrated on recalling it. Any subject can be said to have a meta-theory, which is the theoretical consideration of its foundations and methods.

In Greek mythology, Meta was the first wife of Aegeas. She bore him no heirs.
