7.3 Metadata

There are many confusing definitions of metadata, not helped by the fact that one man's data is another man's metadata. We will use a very simple definition by exclusion.

Metadata is everything other than the raw data that we will analyse.

This definition runs the risk of being too broad, but there is a greater danger from too little metadata being stored and shared rather than too much, so anything that might accidentally lead to an over abundance of metadata is a risk worth taking.
