language for algebraic specification, with a late
binding mechanism. More precisely, we introduce a
special kind of functions called methods, for which,
differently to what happens for usual functions,
overloading resolution is delayed at evaluation time
and not required to be conservative. The extension
consists, at the semantic level, in the definition of
an institution LBInst supporting late binding which is
defined on top of the standard subsorted institution of
\textsc{Casl} and, at the linguistic level, in the
enrichment of the \textsc{Casl} language with
appropriate constructs for dealing with methods. In
addition to this, we propose a further enrichment of
the \textsc{Casl} language which is made possible by
introduction of late binding, that is a mechanism for
``inheriting'' axioms from a supersort with the
possibility of overriding them. The aim is to obtain
advantages in terms of reuse of specifications similar
to those obtained by inheritance in object-oriented

The notion of a schema is internal to the logic of Z

notion of a schema can only be applied in the context
of Z. By translating Z-schemata to abstract datatypes
these specification techniques can be transformed to
specification techniques using abstract datatypes.
Since the notion of abstract datatypes is institution

specification techniques from the specification

such as the translation frame (e.g., a compiler), the
information system frame, the control frame (or
reactive system frame), \ldots . Each frame is
described along three viewpoints that are application
domains, requirements, and design. Our aim is to use
\textsc{Casl} (or possibly a sublanguage or an
extension of \textsc{Casl} if and when appropriate) to
formally specify the requirements and the design of
particular classes of problems (``problem frames'').
This goal is related to methodology issues for
\textsc{Casl}, that are here addressed in a more
specific way, having in mind some particular problem
frame, i.e., a class of systems. It is hoped that this
will provide both a help in using, in a really
effective way, \textsc{Casl} for system specifications,
a link with approaches that are currently used in the
industry, and a framework for the reusability. This
approach is illustrated with some case studies, e.g.,

what is necessary to write relevant, legible, useful
descriptions of the systems to be developed, which will
be the basis of successful developments. This goal was
addressed both from informal approaches (providing in
particular visual languages) and formal ones (providing
a formal sound semantic basis). Informal approaches are
often driven by a software development method, and
while formal approaches sometimes provide a user
method, it is usually aimed at helping to use the
proposed formalism/language when writing a
specification. Our goal here is to provide a companion
method that helps the user to understand the system to
be developed, and to write the corresponding formal
specifications. We also aim at supporting visual
presentations of formal specifications, so as to ``make
the best of both formal and informal worlds''. We
developed this method for the (logical-algebraic)
specification languages \textsc{Casl} (Common Algebraic
Specification Language, developed within the joint
initiative CoFI) and for an extension for dynamic
systems \textsc{Cas-Ltl}, and we believe it is general
enough to be adapted to other paradigms. Another
challenge is that a method that is too general does not
encompass the different kinds of systems to be studied,
while too many different specialized methods and
paradigms result in partial views that may be difficult
to integrate in a single global one. We deal with this
issue by providing a limited number of instances of our
method, fitted for three different kinds of software
items and two specification approaches, while keeping a
common ``meta''-structure and way of thinking. More
precisely, we consider here that a software item may be
a simple dynamic system, a structured dynamic system,
or a data structure. We also support both
property-oriented (axiomatic) and model-oriented
(constructive) specifications. We are thus providing
support for the ``building-bricks'' tasks of
specifying/modelling software artifacts that in our
experience are needed for the development process. Our
approach is illustrated with a lift case study, it was
also used with other large case studies, and when used
on projects by students yielded homogeneous results.
Let us note that it may be used either as itself, e.g.,
for requirements specification, or in combination with
structuring concepts such as the Jackson's problem
frames.",
