Nanobrowser is described in the following publication:
Tobias Kuhn, Paolo Emilio Barbano, Mate Levente Nagy, and Michael Krauthammer. Broadening the Scope of Nanopublications. In Proceedings of the 10th Extended Semantic Web Conference (ESWC). 2013. http://www.tkuhn.ch/pub/kuhn2013eswc.pdf
Some screenshots of the browser interface:
Nanobrowser uses the Virtuoso triple store via its SPARQL endpoint. You should use a separate Virtuoso instance for nanobrowser. Make sure that the SPARQL endpoint is accessible to nanobrowser but not directly to web users.
The following commands have to be executed to configure the Virtuoso triple store:
GRANT EXECUTE ON DB.DBA.RDF_QUAD TO "SPARQL";
GRANT DELETE ON DB.DBA.RDF_QUAD TO "SPARQL";
GRANT EXECUTE ON DB.DBA.SPARUL_CLEAR TO "SPARQL";
GRANT EXECUTE ON DB.DBA.SPARQL_INSERT_DICT_CONTENT TO "SPARQL";
GRANT EXECUTE ON DB.DBA.SPARQL_DELETE_DICT_CONTENT TO "SPARQL";
To load a (large) file of nanopubs in N-Quads format to Virtuoso:
ttlp_mt (file_to_string_output ('file.nq'), '', 'http://example.org/foo', 512);
