Bringing network effects to pervasive spaces

The Obje Interoperability Framework, a middleware technology that lets networked applications and services coordinate with each other, is developed. Obje lets devices declare the formats they can provide, and recipients can declare which formats they can execute. Work on the Obje infrastructure has revolved around defining a set of development-time agreements that are as minimal as possible, while allowing the greatest possible flexibility. Tools to support easy end-user composition by letting end users create assemblages of devices and services that can support them in their tasks are being developed.
