{A new notion is given for the \emph{implementation} of one
specification by another. Unlike most previous notions, this
generalises to handle parameterised specifications as well as
\emph{loose} specifications (having an assortment of non-isomorphic
models). Examples are given to illustrate the notion. The definition
of implementation is based on a new notion of the \emph{simulation}
of a theory by an algebra. For the bulk of the paper we employ a
variant of the Clear specification language [BG77] in which the notion
of a \emph{data constraint} is replaced by the weaker notion of a
\emph{hierarchy constraint}. All results hold for Clear with data
constraints as well, but only under more restrictive conditions.
We prove that implementations compose \emph{vertically} (two
successive implementation steps compose to give one large step) and
that they compose \emph{horizontally} under application of
(well-behaved) parameterised specifications (separate implementations
of the parameterised specification and the actual parameter compose to
give an implementation of the application).},

title = {Semantics, Implementation and Pragmatics of {C}lear,
a Program Specification Language},

year = 1982,

{Specifications are necessary for communicating decisions and
intentions and for documenting results at many stages of the program
development process. Informal specifications are typically used
today, but they are imprecise and often ambiguous. Formal
specifications are precise and exact but are more difficult to write
and understand. We present work aimed toward enabling the practical
use of formal specifications in program development, concentrating on
the Clear language for structured algebraic specification.
Two different but equivalent denotational semantics for Clear are
given. One is a version of a semantics due to Burstall and Goguen
with a few corrections, in which the category-theoretic notion of a
colimit is used to define Clear's structuring operations independently
of the underlying ``institution'' (logical formalism). The other
semantics defines the same operations by means of straightforward
set-theoretic constructions; it is not institution-independent but it
can be modified to handle all institutions of apparent interest.
Both versions of the semantics have been implemented. The
set-theoretic implementation is by far the more useful of the two, and
includes a parser and typechecker. An implementation is useful for
detecting syntax and type errors in specifications, and can be used as
a front end for systems which manipulate specifications. Several
large specifications which have been processed by the set-theoretic
implementation are presented.
A semi-automatic theorem prover for Clear built on top of the
Edinburgh LCF system is described. It takes advantage of the
structure of Clear specifications to restrict the available
information to that which seems relevant to proving the theorem at
hand. If the system is unable to prove a theorem automatically the
user can attempt the proof interactively using the high-level
primitives and inference rules provided.
We lay a theoretical foundation for the use of Clear in systematic
program development by investigating a new notion of the
implementation of a specification by a lower-level specification.
This notion extends to handle parameterised specifications. We show
that this implementation relation is transitive and commutes with
Clear's structuring operations under certain conditions. This means
that a large specification can be refined to a program in a gradual
and modular fashion, where the correctness of the individual
refinements guarantees the correctness of the resulting program.},

{An extension to the Edinburgh LCF interactive theorem-proving system

upon ideas from the Clear specification language. A new theory can be
built from an existing theory in two new ways: by \emph{renaming} its
types and constants, or by \emph{abstraction} (forgetting some types
and constants and perhaps renaming the rest). A way of providing
\emph{parameterised} theories is described. These theory-building
operations --- together with operations for forming a \emph{primitive}
theory and for taking the \emph{union} of theories --- allow large
theories to be built in a flexible and well-structured fashion.
Inference rules and strategies for proof in structured theories are
also discussed.}}

{A specification formalism with parameterisation of an arbitrary order
is presented. It is given a denotational-style semantics, accompanied
by an inference system for proving that an object satisfies a
specification. The inference system incorporates, but is not limited
to, a clearly identified type-checking component.
Special effort is made to carefully distinguish between parameterised
specifications, which denote functions yielding classes of objects,
and specifications of parameterised objects, which denote classes of
functions yielding objects. To deal with both of these in a uniform
framework, it was convenient to view specifications, which specify
objects, as objects themselves, and to introduce a notion of a
specification of specifications.
The formalism includes the basic specification-building operations of
the ASL specification language. This choice, however, is orthogonal
to the new ideas presented. The formalism is also
institution-independent, although this issue is not explicitly
discussed at any length here.},

{Parameterisation is an important mechanism for structuring programs
and specifications into modular units. The interplay between
parameterisation (of programs and of specifications) and specification
(of parameterised and of non-parameterised programs) is analysed,
exposing important semantic and methodological differences between
specifications of parameterised programs and parameterised
specifications. The extension of parameterisation mechanisms to the
higher-order case is considered, both for parameterised programs and
parameterised specifications, and the methodological consequences of
such an extension are explored.
A specification formalism with parameterisation of an arbitrary order
is presented. Its denotational-style semantics is accompanied by an
inference system for proving that an object satisfies a specification.
The formalism includes the basic specification-building operations of
the ASL specification language and is institution independent.}}

{In the theory of algebraic specifications, many-sorted algebras are
used to model programs: the representation of data is arbitrary and
operations are modelled as ordinary functions. The theory that
underlies the formal development of programs from specifications takes
advantage of the many useful properties that these models enjoy.
The models that underlie the semantics of programming languages are
different. For example, the semantics of Standard~ML uses rather
concrete models, where data values are represented as closed
constructor terms and functions are represented as ``closures''. The
properties of these models are quite different from those of
many-sorted algebras.
This discrepancy brings into question the applicability of the theory
of specification and formal program development in the context of a
concrete programming language, as has been attempted in the
Extended~ML framework for the formal development of Standard~ML
programs. This paper is a preliminary study of the difference between
abstract and concrete models of specifications, inspired by the kind
of concrete models used in the semantics of Standard~ML, in an attempt
to determine the consequences of the discrepancy.}}

and on the other hand dependencies between the module elements to be
spelled out explicitly. Algebraic constructions are specified in a
very natural way by means of ordinary algebraic specifications. They
are combined using a sum operation which captures as special cases
various operations on (parameterised) modules offered by standard
specification and development frameworks. We show the expected
composability result for the sum of algebraic constructions and of
their specifications.}}

{The notion of module extraction has been studied extensively in the
ontology community. The idea is to extract, from a large ontology,
those axioms that are relevant to certain concepts of interest
(formalised as a subsignature). The technical concept used for the
definition of module extraction is that of inseparability, which is
related to indistinguishability known from observational specifications.
Module extraction has been studied mainly for description logics and
the Web Ontology Language OWL. In this work, we generalise previous
definitions and results to an arbitrary inclusive institution. We reveal
a small inaccuracy in the formal definition of inseparability, and
show that some results hold in an arbitrary inclusive institution,
while others require the institution to be weakly union-exact.
This work provides the basis for the treatment of module extraction
within the institution-independent semantics of the distributed
ontology, modeling and specification language (DOL), which is
currently under submission to the Object Management Group (OMG).}}

{The Extended ML specification language provides a framework for the
formal stepwise development of modular programs in the Standard ML
programming language from specifications. The object of this paper is
to equip Extended ML with a semantics which is completely independent
of the logical system used to write specifications, building on Goguen
and Burstall's work on the notion of an \emph{institution} as a
formalisation of the concept of a logical system. One advantage of
this is that it permits freedom in the choice of the logic used in
writing specifications; an intriguing side-effect is that it enables
Extended ML to be used to develop programs in languages other than
Standard ML since we view programs as simply Extended ML
specifications which happen to include only ``executable'' axioms.
The semantics of Extended ML is defined in terms of the primitive
specification-building operations of the ASL kernel specification
language which itself has an institution-independent semantics.
It is not possible to give a semantics for Extended ML in an
institutional framework without extending the notion of an
institution; the new notion of an \emph{institution with syntax} is
introduced to provide an adequate foundation for this enterprise. An
institution with syntax is an institution with three additions: the
category of signatures is assumed to form a concrete category; an
additional functor is provided which gives concrete syntactic
representations of sentences; and a natural transformation associates
these concrete objects with the ``abstract'' sentences they represent.
We use the first addition to ``lift'' certain necessary set-theoretic
constructions to the category of signatures, and the other two
additions to deal with the low-level semantics of axioms.},

decomposition into parts is specified by a CASL-style architectural
specification and the parts (\emph{units}) are developed separately,
perhaps by an independent supplier. We consider how to test such
units without reference to their context of use. This problem is most
acute for generic units where the particular instantiation cannot be
predicted.}}

{Component based design and development of software is one of the most
challenging issues in software engineering. In this paper, we adopt a
somewhat simplified view of software components and discuss how they
can be conveniently modeled in a framework that provides a modular
approach to formal software development by means of stepwise
refinements. In particular we take into account an observational
interpretation of requirements specifications and study its impact on
the definition of the semantics of specifications of (parametrized)
components. Our study is carried out in the context of CASL
architectural specifications.}}

{The way that refinement of individual ``local'' components of a
specification relates to development of a ``global'' system from a
specification of requirements is explored. Observational
interpretation of specifications and refinements add expressive power
and flexibility while bringing in some subtle problems. Our study of
these issues is carried out in the context of CASL architectural
specifications. We introduce a definition of observational
equivalence for CASL models, leading to an observational semantics for
architectural specifications for which we prove important properties.
Overall, this fulfills the long-standing goal of complementing the
standard semantics of CASL specifications with an observational view
that supports observational refinement of specifications in
combination with CASL-style architectural design.},

{An applicative language called HOPE is described and discussed. The
underlying goal of the design and implementation effort was to produce
a very simple programming language which encourages the construction
of clear and manipulable programs. HOPE does not include an
assignment statement; this is felt to be an important simplification.
The user may freely define his own data types, without the need to
devise a complicated encoding in terms of low-level types. The
language is very strongly typed, and as implemented it incorporates a
typechecker which handles polymorphic types and overloaded operators.
Functions are defined by a set of recursion equations; the left-hand
side of each equation includes a pattern used to determine which
equation to use for a given argument. The availability of arbitrary
higher-order types allows functions to be defined which ``package''
recursion. Lazily-evaluated lists are provided, allowing the use of
infinite lists which could be used to provide interactive input/output
and concurrency. HOPE also includes a simple modularisation facility
which may be used to protect the implementation of an abstract data
type.}}
