Helpful Virtuoso documentation links
- 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.
- Within isql:
- Removing all triples
- Within isql:
sparql clear graph <http://kb.phenoscape.org/> ;
- Within isql:
- 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
- Within isql:
- Full-text indexing
- Within isql:
DB.DBA.RDF_OBJ_FT_RULE_ADD (null, null, 'All');
- Within isql:
- Performance tuning
- Add index on predicate:
CREATE BITMAP INDEX RDF_QUAD_PGOS ON DB.DBA.RDF_QUAD (G, P, O, S) PARTITION (O VARCHAR (-1, 0hexffff));
- adjust memory settings
- Add index on predicate:
- Configure CORS (Cross-Origin Resource Sharing) to allow SPARQL queries from any web application
