Specification and incremental maintenance of linked data mashup views

The Linked Data initiative promotes the publication of previously isolated databases as interlinked RDF datasets, thereby creating a global scale data space, known as the Web of Data. Linked Data Mashup applications, which consume data from the multiple Linked Data sources in the Web of Data, are confronted with the challenge of obtaining a homogenized view of this global data space, called a Linked Data Mashup view. This paper proposes an ontology-based framework for formally specifying Linked Data Mashup views, and a strategy for the incremental maintenance of such views, based on their specifications.
