Title: Execution Metadata
-The execution metadata provide detailed information about an ongoing/completed
enhancement process. Basically they describe how the
[ExecutionPlan](chains/executionplan.html) provided by the
[Chain](chains.enhancementchain.html) was executed by the
[EnhancementJobManager](enhancementjobmanager.html). Both the ExecutionMetadata
and the ExecutionPlan are provided with the ContentItem as an own content part
of the type MGraph with the URI

For users of the Stanbol Enhacer the Execution Metadata are of interest to:
* check progress of asynchronously started Enhancement Processes: Metadata for
all planed executions of engines are created as soon as an ContentItem is
parsed to the EnhancementJobManager and are updated as soon as the execution of
engines start/complete/fail.
* Monitor the performance of different EnhancementEngines: The Execution
Metadata provide detailed information about starting/completion time points for
engine executions.
