This folder is created the first time the rdf_import API is called (with values for pUser and pPassword). 1. DB.DBA.rdf_import(in URL varchar, in mode integer, [in graph varchar]) 1. Parameters: <verbatim> pURL - RDF URL source; pMode - 0 or 1; 1 - sponger mode (default); 0 - normal mode pGraph - if empty, pURL is used as graph; pUser - user name. - If value is given then a new file is created in the folder '<home>/Uploads/RDF'. - This is dynamic resource - sparql query that select all triplets from the graph pURL - and output format 'RDF' (optional); pPassword - user password (optional); pFolder - destination folder path (optional). - If not set then default folder is used from the user's home - directory - '[home dir]/Uploads/RDF/'. - The folder path must end with '/'. - The pUser must have write permissions for pFolder; </verbatim> 1.
