AnalysisEngineDescription.getDelegateAnalysisEngineSpecifiers() gives you more than just the names. It returns a map whose values are AnalysisEngineDescription objects. From an AnalysisEngineDescription object you can get the AnalysisEngineMetadata. However, I think the best way to allow setting delegate parameters is for your aggregate descriptor to declare parameter overrides. Then you can just set parameter values on the aggregate's parameters and you don't need to mess with the values for individual delegates; they'll be overridden automatically. -Adam
