Open terminology can refer to a higher-order concept (e.g. the ‘‘philosophy of openness’’); the nature of resources (e.g. ‘‘open data’’); the nature of processes (e.g. ‘‘open innovation’’); or the effects on specific domains (e.g. ‘‘open education’’) [...] The principles typically used to characterize this higher-order concept are: access to information and other resources; participation in an inclusive and often collaborative manner; transparency of resources and actions; and democracy or ‘‘democratization’’ such as the breaking up of exclusionary structures.[1]
