document: Semantic navigation on the web of data : specification of routes , web fragments and actions The massive semantic data sources linked in the Web of Data give new meaning to old features like navigation ; introduce new challenges like semantic specification of Web fragments ; and make it possible to specify actions relying on semantic data . In this paper we introduce a declarative language to face these challenges . Based on navigational features , it is designed to specify fragments of the Web of Data and actions to be performed based on these data . We implement it in a centralized fashion , and show its power and performance . Finally , we explore the same ideas in a distributed setting , showing their feasibility , potentialities and challenges .
