The SmartProducts Network of Ontologies (SPO) provides a clear specification of the conceptual model underlying the work on the SmartProducts project, and maximises interoperability not just among all SmartProducts applications, but also between these and other applications in related domains. SPO comprises three different sets of modules, which reflect different levels of abstraction and reuse, from the most generic to the application-specific ones. Because each layer is itself divided into several sub-modules, we obtain a highly modular design, which makes it possible to reduce the parts to be used by a device, depending on its functionalities - e.g., no need to use the process model on devices that only serve as data providers.

The SmartProducts Food Domain Model defines concepts and properties specific for the Philips use case (cooking domain)

The Food Taxonomy contains food taxonomy constructed using PowerAqua and edited manually.

The Food nutrients ontology contains nutritional information fromm Freebase and defines individuals for a "dummy" test scenario for Philips.
