A “tag” is a label that can be added to a CADF Event Record to qualify or categorize an event.

Tags provide a powerful mechanism for adding domain-specific identifiers and classifications to CADF Event Records that can be referenced by the CADF Query Interface. This allows customers to construct custom reports or views on the event data held by a provider for a specific domain of interest. A CADF Event Record can have multiple tags that enable cross-domain analysis.
