RFC 3354                  IOTP V2 Requirements               August 2002


1. Introduction

   Version 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 digital signature [RFC
   2802] parts of IOTP v1 with standards based mechanisms [RFC 3275].

   This document gives requirements for the Internet Open Trading
   Protocol (IOTP) Version 2 by describing design principles and scope
   and dividing features into those which will, may, or will not be
   included.

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 Schemas and XML examples in the
      specification to insure that they are well-formed.

   5. Create usage/implementation guidance information, probably as a
      separate document.

   6. It should be designed to work well with other protocols such as
      ECML [RFC 3106].

   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.  I.E.,
      transactions will not be limited, as with v1, to a single payment
      and a single delivery with delivery occurring after payment.
