Summary

A data object is a named set of data objects. It could have more than one name. An empty data object is a reference if its name indicates an object, otherwise it is a value. If a data object is non-empty, its set of objects is its attributes or properties.
Where does data type fit into this? I think it's just an attribute of a data object. (cbb 1/90)

Quote: use abstract syntax expressions to define, construct, analyze, and classify sets of abstract expressions; e.g., APPL = [opr: EXP, opnd: EXP] defines a set APPL, selectors opr and opnd, classifier appl?, and constructor mk-appl [»reynJC8_1972]
Quote: APPL = [opr: EXP, opnd: EXP] defines a set APPL, selectors opr and opnd, classifier appl?, and constructor mk-appl
