A Middleware Supporting Context-Aware Services Based on Context Business Objects
Although the demand for context-aware applications seems very high, not many applications are in real use. Besides the strenuosity, their insufficient adaptability to changing environment is a major reason. To address the issue, we proposed a VINCA-cc approach and a context middleware to support business-level dynamic configuration of context-aware service. In our approach, all kinds of context information are abstracted to standardized context business objects (CBO), registered in the context middleware. The business-level context model,CBO, represents a set of business-level properties and abstract unified operations that are applicable to all context information. Based on the visual business-level service composition language-VINCA and CBO model,context-aware services can be visually (re-)configured at the business-level. The paper focuses on the context middleware, CBO model and its application.
