SPAM: a SPARQL analysis and manipulation tool

SQL developers are used to having elaborate tools which help them in writing queries. In contrast, the creation of tools to assist users in the development of SPARQL queries is still in its infancy. In this system demo, we present the SPARQL Analysis and Manipulation (SPAM) tool, which provides help for the development of SPARQL queries. The main features of the SPAM tool comprise an editor with both text and graphical interface, as well as various functions for the static and dynamic analysis of SPARQL queries.
