In this paper we discuss the idea of Web Service market places as an extended point of view towards the SOA paradigm. As existing business applications include software functionality which can be reused in new applications the idea of a shared management among allied (federated) network nodes as participants of a superordinated union of software providers and software consumers arises. Having a look at the example of a Federated ERP system we show the advantages and challenges coming along with this idea. As one of the most important issues to be considered in this context we discuss a decentralized approach for the establishment of trust relationships in federated networks. In this approach Web Service consumers rate Web Service providers, that support the competitive behavior between Web Service providers in a market-oriented system.
