Architectures for internal Web services deployment

There is a new emerging world of web services. In this world, services will be combined in innovative ways to form elaborate services out of building blocks of other services. This is predicated on having a common ground of vocabulary and communication protocols operating in a secured environment. Currently, massive standardization efforts [UDDI, WSDL, ebXML, RosettaNet] are aiming at achieving this common ground. We explore possible architectures for deploying computerized traders internal services. This encompasses both the structure and the functionalities of “traders ” and “services ” and the form in which these functionalities could be realized in actual implementations. We consider elaborate services such as negotiation services and marketplaces and their role in this new emerging environment 1. Web Services and Traders The term web service is used to refer to functionalities that a web entity (the service provider) makes available to other web entities (the service consumer, or more generally, the service trader as the consumer may, in turn, be a provider as well). By making a web service available, sufficient information regarding the service is disclosed. This information includes meta-information regarding the service and its provider as well as specific technical data on how to programmatically activate th
