Examples
The following example shows the use of this function for a geometry with SRID 8307 The COLA_MARKETS table is the one from the simple example in Oracle Spatial Developer's Guide.
INSERT INTO cola_markets VALUES( 10, 'cola_x', SDO_GEOMETRY( 2003, 8307, -- SRID NULL, SDO_ELEM_INFO_ARRAY(1,1003,3), SDO_ORDINATE_ARRAY(1,1, 6,13) ) ); commit; SELECT sem_apis.convert_to_gml311_literal(shape) as gml1 FROM cola_markets; "<gml:Polygon srsName=\"SDO:8307\" xmlns:gml=\"http://www.opengis.net/gml\"><gml :exterior><gml:LinearRing><gml:posList srsDimension=\"2\">1.0 1.0 6.0 1.0 6.0 13.0 1.0 13.0 1.0 1.0 </gml:posList></gml:LinearRing></gml:exterior></gml:Polygon> "^^<http://www.opengis.net/ont/geosparql#gmlLiteral>
