6.3.2.1 Introduction

The process of direct communication is simple and only has the steps set out below, e.g., for the communication between a licensee and a licensor. There are several approaches to this communication, depending on which of the two parties offers a web service. The first two cases are asymmetric in that only one of the two parties offers a web service. These cases are subsets of the hub-based choreography. The last case is where both companies offer a web service and this is, in turn a subset of the asymmetric cases.
