A generative approach to the implementation of language bindings for the Document Object Model

The availability of a C implementation of the Document Object Model (DOM) offers the interesting opportunity of generating bindings for different programming languages automatically. Because of the DOM bias towards Java-like languages, a C implementation that fakes objects, inheritance, polymorphism, exceptions and uses reference-counting introduces a gap between the API specification and its actual implementation that the bindings should try to close. In this paper we overview the generative approach in this particular context and apply it for the generation of C++ and OCaml bindings.
