Importing and Exporting RDF Ntriples from IMM

A question that always comes up is how to bulk export and bulk import raw nTriples or RDF/XML into and out of the IMM Semantic Store.

Its actually quite simple. You should open up the RDFQA.exe application in the %Program Files%\Microsoft Interactive Media Manager\Semantic Metadata Store folder, connect to your database, and then execute the following commands.

USE IMM;  Export data as [c:/backup/mydata.rdf]; 
var datas = new DataSource("inet?url=C:\\backup\\mydata.rdf.1&
            parsetype=ntriples"); 
//insert  {?p ?s ?o} into data using #datas where {?p ?s ?o}; 
LOAD {?p ?s ?o} INTO data USING #datas;

As you notice here I commented out the insert command. Insert can be used for small loads, but for larger bulk loads of nTriples or rdf/xml you should use the LOAD command. The LOAD command is targeted at bulk imports.

To parse ntriples, set the parsetype=ntriples. For Rdf/XML set the parsetype=rdf.
