In process mining, event logs have traditionally been considered as strictly hierarchical lists of events, where each event belongs to exactly one case, refers to exactly one activity and has a timestamp. Based on this assumption, the XES standard has been developed to describe event logs. In this paper, we reconsider the notion of an event log, by focussing on events as the primary entity. Furthermore, we do not assume the presence of traditional notions like cases and timestamps (or even ordering), but we introduce mappings for sorting and grouping our KeyValueSets. This allows us to provide a generic transformation from a wide variety of formats to standard XES logs.
