What is Metadata?

Put simply, it’s data about data. The who, what, when, where and how that outlines the properties and tags to categorise the information on a piece of data, defining its purpose. 

Take, for example, a digital image. The file may tell you the size of the image, the date & time it was taken, what type of camera was used, and where the photo was taken. This is metadata, it gives you more insight into the data asset.
