Re: Setting WARN_BAD_NAME when reading RDF/XML file has no effect

[Andy Seaborne]

Mark,

Thanks you for a complete, minimal, example which made the point 
perfectly.

The best way I could find for the current Jena release is to suppress 
warnings by setting the error handler to one that does not out warnings.

     RDFParser.create()
        .errorHandler(ErrorHandlerFactory.errorHandlerNoWarnings)
        .source("test-bad-warn.xml")
        .parse(model.getGraph());

But that's all warnings which is unsatisfactory.

The other way would be to create the underlying ARP parser and set 
options directly. That is poking around in non-public APIs.

JIRA ticket JENA-1494 [1] is for adding a way to set properties specific 
to RDF/XML reading.

There is a pull request [2] for next release which would enable RDF/XML 
specific settings:

    Map<String, Object> properties = new HashMap<>();
    // See class ARPErrorNumbers for the possible ARP properies.
    properties.put("WARN_BAD_NAME", "EM_IGNORE");

    // Put a properties object into the Context.
    Context cxt = new Context();
    cxt.set(SysRIOT.sysRdfReaderProperties, properties);

    Model model = ModelFactory.createDefaultModel();
    // Build and run a parser
    RDFParser.create()
         .source("test-bad-warn.xml")
         .context(cxt)
         .parse(model);

Please find attached an example.

Unzip and execute "mvn compile exec:java" to see the WARN.

Thanks,

    Hi,

    Could you please turn this into complete, minimal example by supplying a
    small amount of data that illustrates the problem.
