This paper proposes the usage of a software framework, based on the Smart Box application model, for the development of applications or appliances of the Smart Box application domain. This class of ubiquitous computing applications can be described as automatic content monitoring applications using Auto-ID technologies such as Radio Frequency Identification (RFID). The Smart Box application model is based on the concepts of location and object to represent a kind of a box and the items and persons that are related to the box. States defined through conditions abstract from the content of the box and limit notification of the application to exceptional cases. Implementing the model and framework we could show that the model is adequate to describe the Smart Box application domain and that the framework decreases the development effort of Smart Box applications.
