+METADATA:
+    Metadata consist of information that characterizes data.
+    Metadata are used to provide documentation for data products.

+    every facet of the data that are being documented.
+
+METADATA AND PRIVACY:
+    Metadata within a file can tell a lot about you.
+    Cameras record data about when a picture was taken and what
+    camera was used. Office documents like pdf or Office automatically adds
+    author and company information to documents and spreadsheets.
+    Maybe you don't want to disclose those informations on the web.
