Recognising the World Wide Web as both a disruptive and pervasive technology, in tandem with the emergence of devices with widely ranging capabilities through which it is navigated, the role of the Web as an information system in pervasive computing is becoming an important concern. A key characteristic of the Web is the ability to access distributed resources, navigating between them by following links. However, this relatively static interaction model is not suitable in scenarios where resources are not at 'well known' locations, for example when copies or versions exist locally. This thesis concerns an augmentation of the Web to provide access to spontaneously available local resources, enriched with open hypermedia linking, for local participants in an impromptu network. The approach taken has been to identify scenarios that serve to scope the application space and then analyse and develop, through a series of prototype experiments, different enabling infrastructures for hypermedia link services, grounded on the notion of a framework of cooperating components.
