Structure and Unstructured

Content created by The Open Data InstituteDocuments vs DataFor documents the machine is told where to put different things on screen to suit humans. Very fixed output.

Given data, the machine can decide how to use it and how to display it best without the need to be told explicitly by a human.

Content created by The Open Data InstituteData formatsXMLJSONCSVThe occasional XLSXLS and CSV can also be unstructured!
