{
    MetadataSearchOptions options = new MetadataSearchOptions();
    // search for signatures in document
    List<MetadataSignature> signatures = signature.Search<MetadataSignature>(options);
    foreach (var metadataSignature in signatures)
    {
        Console.WriteLine("Metadata signature found. Name : {0}. Value: {1}", metadataSignature.Name, metadataSignature.Value);
