Example 28 with LinkedHashModel

the class Rio method parse.

/**
 * Adds RDF data from a {@link Reader} to a {@link Model}, optionally to one or more named contexts.

 * such data using an InputStream is to be preferred.</b>
 *
 * @param reader
 *        A Reader from which RDF data can be read.
 * @param baseURI

 *        these contexts, ignoring any context information in the data itself.
