RESUMO
Semantic Web technologies like RDF model, URIs and SPARQL query language, can reduce the complexity of data integration by making use of properly established and described links between sources.However, the difficulty to formulate distributed queries has been a challenge to harness the potential of these technologies due to autonomy, distribution and vocabulary of heterogeneous data sources. This scenario demands effective mechanisms for integrating data on Linked Data.Linked Data Mashups allow users to query and integrate structured and linked data on the web. This work proposes two architectures of Linked Data Mashups: one based on the use of mediators and the other based on the use of Linked Data Mashup Services (LIDMS). A module for efficient execution of federated query plans on Linked Data has been developed and is a component common to both proposed architectures.The execution module feasibility has been demonstrated through experiments. Furthermore, a LIDMS execution Web environment also has been defined and implemented as contributions of this work.
