Overcoming the Multiplicity of Languages and Technologies for Web-Based Development Using a Multi-paradigm Approach

In this paper, we present QHTML, a library for building Web-based applications in Oz. QHTML provides the Oz programmer with a basic set of abstractions through which creating Web-based interfaces becomes similar to traditional graphical toolkits. In the mean time, QHTML is an experiment investigating whether a single language can replace the numerous ad-hoc combined languages/technologies currently used for building Web-based interfaces. QHTML is realized thanks to the multi-paradigm features of the Oz programming language, which supports symbolic data structures, a functional programming style, an object-oriented style and concurrency via dataflow and lightweight threads.
