M etadata
Data about Data (official definition)
Inform ation that describes a resource (data) so it can be understood
Ensures we find and use the right data for the right purpose
And used correctly
Geographic M etadata

A Key interoperability technology:Producers explain their productUsers learn about products
Non standard products can be understood4
