A specialization of DevisedPracticeOrWork (q.v.). Each instance of ConceptualWork is a partially abstract work (in the sense that each instance has a beginning in time, but lacks a location in space) which either has an associated AbstractInformationStructure (q.v.) or has a version with an associated AbstractInformationStructure. Conceptual works or versions of conceptual works can be instantiated in instances of InformationBearingThing (q.v.); every such instantiation of a conceptual work will also be an instantiation of an instance of AbstractInformationStructure. Notable specializations of ConceptualWork include ComputerProgram_CW, VisualWork, and Book_CW. (en)
