FP-Akka marks up the composition of actors in the workflow using YesWorkflow markup. Individual actors in FP-Akka have their internals delegated to classes in FP-KurationServices, where the implementation details tend to be in sets of object oriented classes. For example, SciNameServiceParent is an abstract class, with concrete IPNIService, GBIFService, WoRMSService, children composed with a concrete subclass of AuthorNameComparator. Following the logic of the data processing in the internals of the scientific name validation actor poses challenges for the dataflow oriented YesWorfklow markup.
Timothy McPhillips made the following notes in KURATOR-106 concerning challenges that markup of object oriented code provides for YesWorkflow (YW).
