The document is a slide presentation by Peter Aiken on the importance of metadata. Some key points:
1. Metadata is defined as data that provides information about other data. It is a use of data, not a type of data itself.
2. Metadata should be used as the language of data governance and treated as capabilities rather than technologies.
3. Metadata defines the essence of organizational interoperability and can be leveraged to increase value from data assets. When data is better organized through metadata, its value increases.
