An Imperative for Libraries

E-publishing in libraries: the [Digital] preservation imperative

Purpose – This paper aims to, through an analysis of the current literature, explore the current state of the library e-publishing community and its approach to preservation. Libraries are increasingly proposing publishing services as part of their workwith their communities, and recently, there has been a pronounced interest in providing electronic publishing (e-publishing) services. The libra...

A certified compiler for an imperative language

This paper describes the process of mechanically certifying a compiler with respect to the semantic speciication of the source and target languages. The proofs are performed in type theory using the Coq system. These proofs introduce speciic theoretical tools: fragmentation theorems and general induction principles. Un compilateur certiii pour un langage impratif RRsumm : Cet article ddcrit la ...

An Imperative Core Calculus for Java

This technical report presents the specification of a programming language Cool: the Core Object-Oriented Language. Cool is a small language but retains many of the features of modern class-based object-oriented languages, including primitive types, classes, inheritance, objects, instance variables and methods, dynamic method binding, null and arrays, etc.. The specification for Cool in this re...

An Imperative Object Calculus

1 Abstract. We develop an imperative calculus of objects. Its main type constructor is the one for object types, which incorporate variance annotations and Self types. A subtyping relation between object types supports object subsumption. The type system for objects relies on unusual but beneficial assumptions about the possible subtypes of an object type. With the addition of polymorphism, the...
