+# EiffelFlowContextDefined
+The EiffelFlowContextDefined describes the context of other events, answering questions such as "Which project is change part of?" or "Which track does artifact belong to?". In this way it offers a method of classifying and structuring one's continuous integration and delivery system and thereby facilitaring traceability and searchability. 
+
+The nature of the described context can vary. The event consequently offers a high degree of flexibility in its description, and none of its member fields are mandatory. Instead they can picked and mixed to fit the situation.
+
+## Data Members
+### data.product
+__Type:__ String  
+__Required:__ No

+__Required:__ No  
+__Description:__ A project context which other events can relate to (e.g. "This test is part of the Killer Feature project.").
+
+### data.program
+__Type:__ String  
+__Required:__ No  
+__Description:__ A program context which other events can relate to (e.g. "This source change was made for the Zero Bugs program.").
