The Word Metadata

• Meta – About– After

• Metadata– Data about data– Other stuff apart from the data that helps

you make use of it

Achilles: Tell me, Mr. Genie — what is a meta-wish?

Genie: It's simply a wish about wishes. I am not allowed to grant meta-wishes. It's only in my purview to grant plain ordinary wishes, such as wishing for ten bottles of beer, to have Helen of Troy on a blanket, or to have an all-expense-paid weekend for two at the Copacabana. You know — simple things like that. But meta-wishes I cannot grant, GOD won't permit me to.

Douglas Hofstadter – Gödel, Escher, Bach

Metadata: The Narrow and Wide Sense• The Narrow sense

– A fancy file system with much more than the usual title, size, and date

– The basis of file, asset, and document management• The broad view

– Not about whole files– Any information that describes or contexts– All the names we come up with to encapsulate and

divide info in order to understand and use it
