Abstract With the spread of Machine-to-Machine (M2M) and cloud services, we have become to be able to

use heterogeneous and distributed data. Implementation of the service which judges the context and controls

au-tonomous from these data is expected. We have previously proposed the framework, which can create and manage

in a unified manner context-aware services using heterogeneous and distributed Web services (sensor services,

infor-mation system, state of appliance services and so on). The proposed framework consists of five layers and we define

the context based on the data of the existing Web services, and then define the context-aware service by the ECA

rule that is a set of event, condition and action. In this paper, we implement a platform based on the framework.

The platform has the functions to register, delete, get and edit elements in each layer and to run the services. We

implement these using Java, and publish APIs as the Web service.

Key words Web services, context, event-condition-action rule, home network system, sensor services
