Effective digital transparency largely depends on provision of a notice, which historically has been a static document such as a privacy policy rather than a contextually useful notice or sign. In this paper, we present Open Notice (OPN) network as a solution to address digital governance transparency challenges to make invisible changes to the state of policy (or governance) visible. OPN uses an open notice receipt schema to capture the semantics of a notice, which allows broadcasting changes and automating the tracking of policy changes.
