Eastlake 3rd [Page 2] INTERNET-DRAFT IOTP v2 Requirements February 2001 1. Introduction Verion 2 of the Internet Open Trading Protocol (IOTP) will extend the interoperable framework for Internet commerce capabilities of Version 1 [RFC 2801] as described in Section 3 below. In addition, it will replace the ad hoc XML messaging and digitial signature [RFC 2802] parts of IOTP v1 with standards based mechanisms. This early draft gives requirements for IOTP Version 2 based on the TRADE workging group charter. 2. Design Principles and Scope 1. The specification must describe the syntax and processing necessary for an extension of the interoperable framework for Internet commerce described in IOTP V1.0 [RFC 2801]. 2. Keep changes to IOTP V1.0 to a minimum. 3. Maintain all existing functionality of IOTP V1.0. 4. Test all XML DTDs and/or Schmeas and XML examples in the specification to insure that they are well-formed. 5. Create usage/implementation guidance information. 6. It should be designed to work well with other protocols such as ECML. 7. IOTP Version 2 should be developed as part of the broader Web design philosophy of decentralization, URIs, Web data, and modularity /layering / extensibility. [Berners-Lee, WebData] In this context, this standard should take advantage of existing provider (and infrastructure) primitives. 3. Requirements IOTP Version 2 will include the following: 1. Be a superset of IOTP Version 1. 2. Provide for the Dynamic Definition of Trading Sequences. 3. Include specification of an Offer Request Block. 4. Support Improved Problem Resolution (extend to cover presentation D. Eastlake 3rd [Page 3] INTERNET-DRAFT IOTP v2 Requirements February 2001 of signed receipt to customer support party, etc.) 5. Add provisions to indicate and handle a payment protocol not tunneled through IOTP. The following may be include in IOTP v2: 1. Support for wallet servers. 2. Support Repeated/ongoing payments. 3. Enhanced Server to Server messages. 4. Include the ability to add both fields and attributes to trading blocks. The following are out of scope for IOTP version 2: 1. Legal or regulatory issues surrounding the implementation of the protocol or information systems using it. 2. Design of an XML Messaging Layer. 3. Design of XML Digitial Signatures. 4. Security Considerations As provided above, IOTP v2 will provide optional authentication via standards based XML Digitial Signatures [XMLDSIG]; however, neither IOTP v1 nor v2 provide confidentiality mechanism. Both depend on the security mechanisms of any payment system used in conjuction with them to secure payments and require the use of secure channels such as those provided by TLS [RFC 2246] or IPSEC for confidentiality.
