CASL for ASF+SDF Users

Peter D. Mosses

Abstract


Casl is an expressive language for the algebraic specification
of software requirements, design, and architecture. It has been
developed by an open collaborative effort called CoFI (Common
Framework Initiative for algebraic specification and development).
Casl combines the best features of many previous algebraic
specification languages, and it is hoped that it may provide
a focus for future research and development in the use of algebraic
techniques, as well being attractive for industrial use.
This paper presents Casl for users of the Asf+Sdf framework.
It shows how familiar constructs of Asf+Sdf may be
written in Casl, and considers some problems that may arise
when translating specifications from Asf+Sdf to Casl. It then
explains and motivates various Casl constructs that cannot be
expressed directly in Asf+Sdf. Finally, it discusses the role that
the Asf+Sdf system might play in connection with tool support
for Casl.
