Overview
GXS makes use of web services standards across our portfolio of software and services, and will make more aggressive use of this set of standards as they are adopted by our customers and key standards mature.
Web services are a perfect solution to many supply chain communication challenges, because they provide a means to exchange information that is easy to begin using, without requiring all parties to agree on a vendor, or even a particular technology stack (Java versus .NET versus scripting languages or LAMP). The GXS approach to web services is to develop SOAP-based capabilities that provide access to our software and services, while providing core web services capabilities through partnerships with industry leaders like webMethods and Systinet, and leveraging major open source work like that of the Apache Group.
GXS currently tends to focus its usage of web services on the SOAP (Simple Object Access Protocol) and WSDL (Web Services Description Language) standards. Our current interfaces complement one or more additional protocols used for bulk data transfer (often AS2 or FTP). Current development work involves the use of WS-Security for the GXS Trading Grid Business Services APIs, as well as SAML (Security Assertion Markup Language).
