SPARQL, the W3C standard querying language for RDF (Resource Description Framework), provides rich capabilities for slicing and dicing RDF data. The latest version, SPARQL 1.1, added support for aggregation, nested and distributed queries among others. Nevertheless, the purely declarative nature of SPARQL and the lack of support for common programming patterns, such as recursion and iteration, make it challenging to perform complex data processing and analysis in SPARQL. In the database community, similar limitations of SQL resulted in a surge of proposals of analytics languages and frameworks.
