Class: SpecimenProcessingActivity

An activity that modifies the physical structure, composition, or state of a specimen. Unlike SpecimenCreation, SpecimenProcessing activities do not result in the generation of new entities - they take a single specimen as input, and output that same specimen.

Comments: "Processing" as defined here alters the physical nature of a specimen, such that storage or transport activities do not qualify as processing activities. When instantiating this class, create a separate instances for each type/method of processing performed (e.g. each method of fixation, freezing, labeling, etc. that is applied).
