Limbo: an Ontology based Web Service Compiler for Networked Embedded Devices Final | ||||
| Klaus Marius Hansen, Weishan Zhang, and Goncalo Soares, Department of Computer Science, University of Aarhus, Denmark: Web services are increasingly needed to be adopted as service provision mechanisms in pervasive computing environment. Implementing web services on devices raises a number of challenges. First, the web service should be efficient enough in order to provide usable services on small devices. Second, development of embedded web service must handle the variability and dependencies of hardware and software platforms. And at the same time, device status are changing very often, which are deemed to affect the end user applications. To address these challenges, we developed a web service compiler, Limbo, in which OWL ontologies are used to make the Limbo compiler aware of its compilation context, such as the targeted hardware and software. To achieve context awareness at runtime, we are using a state machine ontology to generate stub code for state changes of a device. |
