Rupert Westenthaler resolved STANBOL-8.
---------------------------------------
Resolution: Fixed
The ExecutionPlan now used by EnhancementChains allows to define optional and
required ExecutionNodes. This alls to define if a failed execution of an engine
should cause the whole enhancement process to fail or not (see STANBOL-431)
> Define/implement error handling strategy for EnhancementJobManager

> URL: https://issues.apache.org/jira/browse/STANBOL-8
> Project: Stanbol
> Issue Type: Improvement
> Components: Enhancer
> Reporter: Rupert Westenthaler
>
> The Interface does not define how to handle EngineExceptions of single
> engines while enhancing parsed content Items.
> The InMemoryJobManager implementation just forwards such exception what
> causes the whole enhancement request to fail if a single Engine encounters an
> exception. This might be the intended behavior in some cases, but might be
> unintended under other conditions. Especially on errors within semantic
> lifting type enhancement engines it might still make sense to return
> enhancement results of previous engines.
> One possible way would also to include an "enhancement report" in the
> response that provides information about errors and warnings during the
> enhancement process. This might be also a nice feature for the still
> unimplemented async. enhancement mode, because than such a report could also
> contain a listing of expected, but still missing enhancement results.
