XML-based Supply Chain Management

In this paper we want to examine, to what extent XML is able to support the exchange of business documents in supply chains. Thereby we focus on the problem of converting different data formats of participants of the supply chain. First results show that XML and its surrounding standards of the XML family highly accelerate and simplify the conversion process. Therefore, XML allows using a common standard on a lower level, without reducing variety on a higher level, due to the use of different XML vocabularies. First, we examine different approaches for solving the transformation problem. Second, we show how XML can actually be implemented for a Web-based integration in supply chains. We present a java-based prototype that enables document exchange over the Internet using XML business vocabularies for document representation, XSLT for document conversion and presentation, and both DOM and SAX for processing and integrating documents into in-house-systems.
