PRISSMA,Towards Mobile Adaptive Presentation of the Web of Data
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
The Problem Web of Data resources must be properly consumed on mobile devices and adapted to the current mobile context.Representation ( , , ) 3
The Proposal Contextual adaptation is performed on Uniform, RDF-based RDF data directly solution Declarative framework to share and re-use presentation Presentation-level information for approach. PRISSMA* Adaptive context-adaptable Interoperates with RDF Representation user interfaces over Fresnel [Pietriga et al 06] RDF data. Framework * Presentation of Resources for Interoperable Semantic and Shareable Mobile Adaptability 4
Early Stage Work – The Modelprissma: UserThe Vocabulary specifiesunder which contextualconditions activate a given DeviceFresnel configuration. Environment PRISSMA is NOT yet another context model. Existing context vocabularies are extensively reused. 5
