Based on equalities. union (1) union: {T}, {U} -> {V} where V =LUB(T, U) (2) union(S 1, S 2) = {vi v belongs to S 1 or v belongs to S 2} This operator returns union of two input sets. difference (1) difference: {T}, {U} -> {T} (2) difference(S 1, S2) = {511 51 belongs to S 1 and 51 does not belong to S2} This operator returns the difference of two input sets. intersection (1) intersection: {T}, {U} -> {V} where V =GLB(T, U) (2) intersection(S 1, S2) = {vlv belongs to S 1 and v belongs to S2} This operator returns the intersection of two input sets.

We define the notion of interpretations I associated with types. (1) I(Di) = Di. (2) ICc) = a function from c to a set of object identifiers. (3)/(lv i belongs to I(Ti) for i=I,2, ... , n }.

The absolute data is translated from the relative data and is used for actual display. The procedural attributes for GRAPHICS also include input, output, display, move, and change-size. TEXT objects have attributes such as string data for storage and graphics text data for display. The TEXT procedural attributes also include input, output, display, move, and change-size. TEXT objects can contain other arbitrary objects as subtexts. IMAGE, GRAPHICS, and TEXT have the same interface for the same manipulation such as move although each implementation differs from one to another.
