Conference Paper
In this paper, we present an approach to exploit Linked Data in Smart Spaces, doing more than just using RDF to represent informa- tion. In particular, we rely on knowledge stored in DBpedia1, a dataset in the Web of Data. We also provide a platform to implement such an approach and a eTourism use case, both developed in collaboration with a mobile...
Conference Paper
Internet has evolved and grown tremendously during the last years. We're living the rise of the “self-made” Web Services. On the one hand, this conception reduces the limitations for the creation of new Web Services capable of operating on top of the large Internet technological foundation, while on the other it has some drawbacks such as: slow cre...

Access control is a recognized open issue when interacting with RDF using HTTP methods. In literature, authentication and authorization mechanisms either introduce undesired complexity such as SPARQL and ad-hoc policy languages, or rely on basic access control lists, thus resulting in limited policy expressiveness. In this paper we show how the Shi...
