Extensibility via a meta-level architecture

Meta-level architectures are recognized as a means to achieve run-time extensibility, and have been applied as such in existing hypermedia systems. Yet, designing a good meta-level architecture is notoriously hard and remains an art rather than a science. This paper shows how to derive a meta-level architecture for hypermedia navigation, thereby providing a way to control how third-party components interact with the linking engine. This extra level of control allows for a better and safer integration between an extensible system and the third-party components extending it.
