The RNIFSender class implements a RosettaNet Implementation Framework (RNIF) client.

Syntax

ipworksedi.Rnifsender

Remarks

The RNIFSender component may be used to send RosettaNet Implementation Framework (RNIF) messages over the TLS/SSL-secured HTTPS transport protocol. RosettaNet is used in a variety of industries including Semiconductor Manufacturing, Electronic Components, Telecommunications, Logistics, the Chemical Industry (through CIDX), and more.

A typical RosettaNet transaction is as follows:

1. The RNIF client creates a RosettaNet message and uploads it to the receiver over HTTPS. The contents and structures of these messages are defined by the RosettaNet community in the form of standardized Partner Interface Processes (PIPs). Due to the sensitive nature of most business documents, such messages will usually be encrypted and wrapped in an S/MIME entity along with a digital signature.
2. Upon receipt of the message, the receiver will verify the transport headers, then will attempt to decrypt the message and verify the digital signature.
3. Once these steps have been completed, the receiving application can process the PIP instance, and either send an acknowledgement of receipt or a reply in the form of another RosettaNet message back to the sender, depending upon the requirements of the particular PIP.

When sending a RosettaNet message, the client, at minimum, must specify the StandardName and StandardVersion of the message being sent in the preamble header. In the delivery header, the client must specify the SecureTransportRequired, MessageDateTime, MessageReceiverId, MessageSenderId, and MessageTrackingId properties. For the service header, all properties that are relevant to the action, reply, or signal must be specified. The client, after setting all appropriate header properties, must then set the content of the RosettaNet message body by setting the ServiceContent property.

Attachments may be added to the RosettaNet message. Attachments are arbitrary files allowed by specific PIPs, and may be simple text documents or pictures of products. Attachments are added to the RosettaNet message by adding instances of RNIFAttachment to the Attachments collection.

To secure the RosettaNet message, the message may be signed and/or encrypted by setting the appropriate certificates. By default, the component will apply the highest level of message security if the appropriate certificates are specified. To sign the data, set Certificate. To encrypt, set RecipientCert. To change which parts of the message, if any, are to be encrypted, set the EncryptionType property.

The final property to be set is the URL to which the client is posting the request. Once this is done, a call to the Post method causes the class to generate, sign, and encrypt the RosettaNet business document and upload it to the server.

NOTE: when the Post method is called, the class will perform a minimal set of checks on the various RosettaNet message headers to ensure that an invalid business message is not sent. If any values in the header are missing or are in conflict, the message cannot be processed by the receiving entity. To avoid a round trip, the class throws an exception with a description of which header field is in error.

The response, may be sent synchronously or asynchronously, whether it is a complete business reply or a simple receipt acknowledgement. To change whether a synchronous or asynchronous response is desired, set the ResponseType before calling Post. If a synchronous response is received after the HTTPS post, ReplyHeaders and ReplyData will be populated appropriately.
