Overview
The XDASv2 specification provides a standardized classification for audit events. It defines a set of
generic events at a global distributed system level. XDASv2 provides a common portable audit
record format to facilitate the merging and analysis of audit information from multiple components
at the distributed system level. The XDASv2 events are encapsulated within a hierarchical
notational system that helps to extend the standard or existing event identifier set.The XDASv2
taxonomy defines a set of fields, of these the primary fields are observer, initiator and target.
