Method Details

convert

public static void convert(URL infileurl,
 String syntax,
 String mappingurl,
 String mappingsyntax,
 TopicMapIF topicmap,
 boolean lenient)
                    throws org.apache.jena.shared.JenaException,
IOException

EXPERIMENTAL: Converts an RDF model into the topic map using the given mapping.

Parameters:

infileurl - the URL to read the input data from

syntax - the syntax of the input data. Values are "RDF/XML", "N3", and "N-TRIPLE". Defaults to "RDF/XML" if null.

mappingurl - the URL to read the mapping from. If null the mapping is taken from the input data.

mappingsyntax - the syntax of the mapping. Values are "RDF/XML", "N3", and "N-TRIPLE". Defaults to "RDF/XML" if null.

topicmap - The topic map to add the converted data to.

lenient - When false, errors are thrown if the RDF data cannot be correctly mapped (for example, a statement type is mapped to a topic name, but has a URI value).

Throws:

org.apache.jena.shared.JenaException

IOException
