A central task in the development of context-aware applications is
the modeling and management of complex context information. In this
paper, we present the NexusEditor, which eases this task by
providing a graphical user interface to design schemas for spatial
context models, interactively create queries, send them to a server
and visualize the results. One main contribution is to show how
schema awareness can improve such a tool: the NexusEditor
dynamically parses the underlying data model and provides additional
syntactic checks, semantic checks, and short-cuts based on the
schema information. Furthermore, the tool helps to design new schema
definitions based on the existing ones, which is crucial for an
iterative and user-centric development of context-aware
applications. Finally, it provides interfaces to existing
information spaces and visualization tools for spatial data like
GoogleEarth.
