The ability to convert between different data formats is important in large and heterogeneous information systems. Although XML was established as an universal standard for data exchange, XML-related languages like XQuery lack the ability to access data in other formats; in particular, relational data and RDF. In this paper, we describe TriQuery - an extension of the XQuery language which adds records (tuples) and RDF-specific operators. Using the statically optimizable record types, relational data as well as the results from RDF sub-queries can be integrated more efficiently than with their traditional encoding using XML elements and attributes.
