Submission request to W3C (W3C Staff Comment)

We, W3C member DataChannel, Inc., hereby submit to the Consortium the following specification comprising the document(s) linked below:

  1. WebBroker Submission
  2. ObjectMethodMessages DTD
  3. AnonymousData DTD
  4. TerseAnonymousData DTD
  5. InterfaceDef DTD
which collectively are referred to as "the submission". We request the submission be known as the "WebBrokering" submission.


This document provides a specification (WebBroker document type definitions, or WebBroker DTDs) for describing and exchanging structured messages between software components on the Web. Such exchange is facilitated by the DTDs which describe the structure of the messages (method requests and method responses) and which also describe the interfaces of the software components themselves. The AnonymousData DTD describes a simple way of expressing the data type of structures which works within XML 1.0 and is designed to work with XML-Data. The ObjectMethodMessages DTD describes how to represent, in XML documents, the serialized messages between software components. ObjectMethodMessages uses the AnonymousData DTD and is modeled after DCE RPC Request and Response PDUs. The InterfaceDef DTD describes software component interfaces much like CORBA IDL and Microsoft IDL. One immediate implication of these ideas is that there can now be a unified Web publishing and traditional client/server programming model which work over HTTP 1.1. We expect the WebBroker DTDs to be useful for enabling many organizations to implement a mature yet simple and easy to reproduce model of distributed computing on the Web.
