...which is where we benefit from shared output formats. XML obviously. 
RDF, less obviously to some. RDF gives you structural similarity across a 
variety of XML-encoded output formats. Instead of needing to know the 
encoding rules used by each service, a generic datamodel-to-encoding 
strategy is used, so that applications share knowledge of the classes/properties 
encoded in the XML, rather than less interesting knowledge of the 
encoding strategies used by each service/site. In that respect, RDF and 
SOAP Encoding are strangely similar...
