Bulk loading RDF source files
- Within isql: ld_dir_all('/usr/local/virtuoso/6.1.4/share/virtuoso/vad/kb', '*.owl', 'http://kb.phenoscape.org/');
- then, rdf_loader_run();
- Before doing the above you may need to delete from db.dba.load_list; to make it reload files that have previously been loaded.
Removing all triples
- Within isql: sparql clear graph <http://kb.phenoscape.org/> ;
Setting default passwords
Inference rules and reasoning
- Within isql: rdfs_rule_set('http://kb.phenoscape.org/', 'http://kb.phenoscape.org/');
  - First arg is name of rule set, second is RDF graph to include
Full-text indexing
- Within isql: DB.DBA.RDF_OBJ_FT_RULE_ADD (null, null, 'All');
Performance tuning
- add index on predicate
- adjust memory settings
Configure CORS (Cross-Origin Resource Sharing) to allow SPARQL queries from any web application
