 An alternative approach is to embrace these findings and abandon the idea of data as fixed representations of reality altogether. Within the relational view, data are objects that are treated as potential or actual evidence for scientific claims in ways that can, at least in principle, be scrutinised and accounted for (Leonelli 2016). The meaning assigned to data depends on their provenance, their physical features and what these features are taken to represent, and the motivations and instruments used to visualise them and to defend specific interpretations. The reliability of data thus depends on the credibility and strictness of the processes used to produce and analyse them. The presentation of data; the way they are identified, selected, and included (or excluded) in databases; and the information provided to users to re-contextualise them are fundamental to producing knowledge and significantly influence its content. For instance, changes in data format—as most obviously involved in digitisation, data compression or archival procedures— can have a significant impact on where, when, and who uses the data as source of knowledge.
