This is a simple program to load multiple SPARQL query result sets and compare using union/intersection/difference.
Results are expected to be in JSON (as according to SPARQL 1.1 Query Results JSON Format specification).

Run the program like so to launch it:
clojure -M -m sparql-result-explorer.core
No command-line arguments or configuration file are needed (or supported).

To perform union/intersection/difference, select multiple entries in the list of loaded files (ctrl+click to add/remove individual items to selection, shift click to select a range of files).
The selected files must contain the same query variables.
