+# Metadata and privacy
+
+Metadata consist of information that characterizes data.                                             
+Metadata are used to provide documentation for data products.                                        
+In essence, metadata answer who, what, when, where, why, and how about                               
+every facet of the data that are being documented.                                                   
+
+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 information on the web. 
+
+This is precisely the job of MAT2: getting rid, as much as possible, of
+metadata.
