Abstract : Research in data warehousing (DW) has developed expressive and efficient tools for the multidimensional analysis of large amounts of data. As more data gets produced and shared in RDF, analytic concepts and tools for analyzing such irregular, graph-shaped, semantic-rich data need to be revisited. We introduce the first all-RDF model for warehousing RDF graphs. Notably, we define analytical schemas and analytical queries for RDF, corresponding to the relational DW star/snowflake schemas and cubes. We also show how typical OLAP operations can be performed on our RDF cubes, and experiments on a fully-implemented platform demonstrating the practical interest of our approach.
