Testcode is the following:

OGVTest.java

	void parse(String fileName) throws Exception {
		InputStream inputStream = new FileInputStream(fileName);
		
		Metadata metadata = new Metadata();
		
		Parser parser = new AutoDetectParser();
		
		ParseContext parserContext = new ParseContext();

		parserContext.set(Parser.class, parser);

		ContentHandler contentHandler = new WriteOutContentHandler(
			new DummyWriter());

		parser.parse(inputStream, contentHandler, metadata, parserContext);
		
		System.out.println(metadata);
	}
