DB.DBA.RDF_TRIPLES_TO_RDF_XML_TEXT

Serializes vector of triples into a session, in RDF/XML syntax.

DB.DBA.RDF_TRIPLES_TO_RDF_XML_TEXT (inout triples any, in print_top_level any, inout ses any);

Description

Serializes vector of triples into a session, in TURTLE syntax. In current version, every triple is printed in separate top-level record (say, in rdf:Description tag), without any pretty-print or nesting optimization.

Parameters

triples – vector of triples in 'long valmode'.

print_top_level – zero if only rdf:Description tags should be written, non-zero if the rdf:RDF top-level element should also be written

ses – an output stream in server default encoding

Examples

create procedure simple_test(in query varchar, in dflt_graph varchar)
{
  declare ses, rset, triples any;
  declare txt varchar;
  ses := string_output ();
  rset := DB.DBA.SPARQL_EVAL_TO_ARRAY (query, dflt_graph, 1);
  triples := dict_list_keys (rset[0][0], 1);
  DB.DBA.RDF_TRIPLES_TO_RDF_XML_TEXT (triples, 1, ses);
  txt := string_output_string (ses);
  dump_large_text (txt);
}
;
