Logical Structure Specification and data type definition

We describe a constructive approach to the specification of data types. The primary motivation for this approach, which is referred to as the Logical Structure - Operation Specification (LSOS), is to highlight certain aspects of a data type, and to possibly suggest one or more implementations for the data type. A key feature of the LSOS is its flexibility, which permits a wide variety of specifications for a data type. This allows the specifier of a data type to communicate to the user any view or perspective which was taken in developing the data type.
