In this article, I would like to share some experiences with a visualisation for the business in a SOA environment. MediaWiki is the basis for the visualisation tool because it is a wide spread and well known environment. For this purpose, the normal static MediaWiki is enhanced with some dynamic features to support hyperlinks for the inter-relations between the entities in the SOA environment.

Chapter 2 will give some background information on the environment where this project has been carried out. Chapter 3 explains the solution which is implemented in the past year whilst chapter 4 presents some ideas for future developments. Chapter 5 finally presents some lessons learned.
