Hello!
So i've tried to run tutorial with *representation *module. But it kept
giving *null. *I've kept track of it and it's giving in this line of
*Parser.class:
*

ParsingProvider provider =
(ParsingProvider)this.providerMap.get(deParameterizedIdentifier);

It can't get the provider and throws
*UnsupportedParsingFormatException.*


*and the output was:
[main] INFO org.apache.clerezza.representation.Parser - constructing Parser
[main] WARN org.apache.clerezza.tutorial.Example02 - text/turtle is
not supported by the used parser

*

Then I tried with the dependencies as written in Tutorial 2. I moved
*example02.ttl *file under *resources *directory of module and made a
change in the code as:
package org.apache.clerezza.tutorial;
import org.apache.clerezza.commons.rdf.Graph;import
org.apache.clerezza.commons.rdf.Triple;import
org.apache.clerezza.rdf.core.serializedform.Parser;import
org.apache.clerezza.rdf.core.serializedform.SupportedFormat;import
org.apache.clerezza.rdf.core.serializedform.UnsupportedFormatException;import
org.slf4j.Logger;import org.slf4j.LoggerFactory;
import java.io.InputStream;import java.util.Iterator;
public class Example02 {

    private static final Logger logger = LoggerFactory.getLogger(
Example02.class );

    public static void main( String[] args ) {

        InputStream inputStream =
Example02.class.getClassLoader().getResourceAsStream( "example02.ttl"
);
        Parser parser = Parser.getInstance();

        try {
            Graph graph = parser.parse( inputStream, SupportedFormat.TURTLE );

            Iterator<Triple> iterator = graph.filter( null, null, null );
            Triple triple;

            while ( iterator.hasNext() ) {
                triple = iterator.next();
                logger.info( String.format( "%s %s %s",
                        triple.getSubject().toString(),
                        triple.getPredicate().toString(),
                        triple.getObject().toString()
                ) );
            }
        } catch ( UnsupportedFormatException ex ) {
            logger.warn( String.format( "%s is not supported by the
used parser", SupportedFormat.TURTLE ) );
        }
    }
}

And i got the output as:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in

I hope i managed to tell what i meant. Just a bit confused why it
didn't work with *representation* module. Should i try with
*representation *or this is fine?

Regards!
