“…They challenged the open hypermedia community to generalize open hypermedia infrastructure to support the structures and services of other application domains. This call led to work on component-based open hypermedia systems and structural computing environments, producing systems such as Callimachus [31], Construct [35], FOHM [20], IUHM [21] and Themis [2,3,16].…”

This paper presents a new definition of context for contextaware computing based on a model that relies on dynamic queries over structured objects. This new model enables developers to flexibly specify the relationship between context and context data for their context-aware applications. We discuss a framework, HyConSC, that implements this model and describe how it can be used to build new contextual hypermedia systems. Our framework aids the developer in the iterative development of contextual queries (via a dynamic query browser) and offers support for context matching, a key feature of contextual hypermedia. We have tested the framework with data and sensors taken from the HyCon contextual hypermedia system and are now migrating HyCon to this new framework.

Structural computing provides techniques and tools to ease the task of developing application infrastructure; infrastructure that provides common services such as persistence, naming, distribution, navigational hypermedia, etc., over a set of application-specific or domain-specific structures. Within structural computing, "structure" refers to a combination of data together with relationships pertaining to that data. Structure servers support the specification and manipulation of structures. One important aspect of structural computing is the power and flexibility it provides application developers constructing new applications. A large part of this power is due to structural computing's ability to provide awareness services for both structure and behavior. We define this concept and describe the awareness services provided by the Themis structural computing environment. The utility of these services are demonstrated by presenting the impact they have had on the InfiniTe information integration environment. In particular, these services help to increase the efficiency and reduce the size of domain-specific applications built using structural computing technology. We conclude by discussing how these services might influence the open hypermedia field and the development of new hypermedia services.
