Abstract : Tables are a common form of query results, notably in SPARQL. However, due to the flat structure of tables, all structure from the RDF graph is lost, and this can lead to duplications in the table contents, and difficulties to interpret the results. We propose an extension of SPARQL 1.1 aggregations to get nested results, i.e. tables where cells may contain embedded tables instead of RDF terms, and so recursively.
