Summary

The authors provide an overview of the federation framework infrastructure and compare existing SPARQL federation frameworks, highlighting their shortcomings and potential research directions. The paper focuses on the challenges of querying data in the Web of Data context, where there is no global schema, and data is heterogeneous in terms of vocabularies. The authors discuss the importance of link establishing among datasets and the use of tools like SILK and LIMES for entity matching. The paper also provides a motivating example of querying data from multiple SPARQL Endpoints, such as Drugbank, DBpedia, and Kegg, to collect drug information.
