Linked data has provided the means for a large number of considerable knowledge resources to be published and interlinked utilizing semantic Web technologies. However it remains difficult to make use of this 'Web of data' fully, due to its inherently distributed and of-ten inconsistent nature. In this paper, the authors introduce core challenges faced when consuming multiple sources of linked data, focusing in particular on the problem of querying. They compare both URI (Uniform Resource Identifier) resolution and federated query approaches, and outline the experiences gained in the development of an application which utilizes a hybrid approach to consume linked data from the unbounded web.
