Manutenção incremental de visões de mashup de dados interligados

Abstract

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 work proposes an ontology-based framework for specifying formally Linked Data Mashup views, and a strategy for incremental maintenance of such views, based on their specifications.
