// Search image metadata in WMF document

// Compose Metadata passing WMF to constructor
try (Metadata metadata = new Metadata("input.wmf"))
{
    // Fetch all metadata properties that fall into a particular category
    IReadOnlyList properties = metadata.findProperties(
        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.");
    for (MetadataProperty property : properties) 
    {
        System.out.println(String.format("Property name: %s, Property value: %s",
