provide guidelines to improve the Findability, Accessibility, Interoperability, and Reuse of digital assets. The principles emphasise machine-actionability because humans increasingly rely on computational support to deal with data as a result of the increase in volume, complexity, and creation speed of data. The principles refer to three types of entities: data (or any digital object), metadata (information about that digital object), and infrastructure.
