Thanks Marshall for your detailed response. Really appreciate it. I have a few more inquiries:

I had a look at the CAS Multiplier and saw that it implements the interface AnalysisComponent http://uima.apache.org/d/uimaj-2.4.2/apidocs/org/apache/uima/analysis_component/AnalysisComponent.html So my question is what is the relationship between this interface and the AnalysisEngine interface http://uima.apache.org/d/uimaj-2.4.2/apidocs/org/apache/uima/analysis_engine/AnalysisEngine.html Conceptually speaking, AE should be subclass of AC but this doesn't seem to be the case? > > Later, it became clear that the Collection Reader and Cas Consumer were just > parameterizations of normal Analysis Engines, so they were replaced by those. > The older classes still work, though.

Again, when you say AE specified as a CAS Multiplier, how does the inheritance relationship work? Thanks again for your help. Regards
