My question basically boils down to this: should XML > messaging be based on a "metadata" language, or on a "domain" > language? I think you'll find a wide variety of opinions on this one. Metadata languages are often easier to apply when you don't have control over the data model of the data you will convert to and from XML. If you control the entire usage of your application (clients and servers) you can easily define a domain language and use that. Most XML applications that define an XML DTD or schema for their specific messages are, of course, domain languages. There are several projects aimed at automatically associating domain languages with general data models. My list is out of date, but the following are some examples of each: * Metadata languages for messaging using XML * LDO-XML <http://casbah.org/LDO/> * ObjectSource <http://www.xml.com/pub/1999/09/serialization/index.html> * SOAP <http://www.develop.com/soap/> * WDDX <http://wddx.org/> * XML-RPC <http://www.xmlrpc.com/> * XP Extensible Protocol, an expired Internet Draft * Messaging support for Domain languages * XMLTP <http://xmltp.org/> * Tieing domain languages to data models * Coins <http://www.jxml.com/coins/> -- Ken MacLeod ken@b... xml-dev: A list for W3C XML Developers.
