The Mobile Web is evolving fast and mobile access to the Web of Data is gaining momentum. Interlinked RDF resources consumed from portable devices need proper adaptation to the context in which the action is performed. This paper introduces PRISSMA (Presentation of Resources for Interoperable Semantic and Shareable Mobile Adapt- ability), a domain-independent vocabulary for displaying Web of Data resources in mobile environments. The vocabulary is the first step to- wards a declarative framework aimed at sharing and re-using presenta- tion information for context-adaptable user interfaces over RDF data. The namespace vocabulary can be found at http://ns.inria.fr/prissma

Web of Data resources
must be properly
consumed on mobile
devices and adapted to
the current mobile

5. Early Stage Work – The Model
prissma:
User
The Vocabulary specifies
under which contextual
conditions activate a given Device
Fresnel configuration.
Environment
PRISSMA is NOT yet another context model.
Existing context vocabularies are extensively reused.
