// Set up input Otp file

// Instantiate Signature for input file
using (var signature = new GroupDocs.Signature.Signature(filePath))
{
        // instantiate metadata signing options
        var options = new MetadataSignOptions();

        // setup Author property
        PresentationMetadataSignature mdSign_Author = new PresentationMetadataSignature("Author", "Mr.Scherlock Holmes");// String value
        options.Signatures.Add(mdSign_Author);
        // setup document data
        PresentationMetadataSignature mdSign_DocData = new PresentationMetadataSignature("CreatedOn", DateTime.Now);// Datetime value
        options.Signatures.Add(mdSign_DocData);
        // setup document id
        PresentationMetadataSignature mdSign_DocId = new PresentationMetadataSignature("DocumentId", 123456);// Integer value
        options.Signatures.Add(mdSign_DocId);
        
        // sign Otp document
        SignResult result = signature.Sign(outputFilePath, options);
