Interest in XML protocols continues to rise, with the recent publication of a batch of articles on MSDN and IBM's developerWorks.

SOAP in the Microsoft .NET Framework and Visual Studio.NET discusses the use of SOAP in Microsoft's NET Remoting, ASP.NET Web Services, and ATL Web Services.

Uche Ogbuji has written a couple of articles at IBM's developerWorks concerning XML protocol-related technologies. Using WSDL in SOAP applications explains WSDL, the Web Services Description Language.

Ogbuji's other article, Supercharging your WSDL with RDF builds a bridge between WSDL and RDF, providing an RDF representation of WSDL information, and explaining how RDF tools might visualize this information.
