        new FallsIntoCategorySpecification(Tags.getContent()));

    // Process found metadata entries
    System.out.println("The metadata properties describing some characteristics of 
        the file content: title, keywords, language, etc.");

    {
        System.out.println(String.format("Property name: %s, Property value: %s",
