Web Services Message Data (WS-MessageData) 0.91

Feb 26, 2003

Introduction

One of the types of information that a SOAP message can carry is meta-data about itself, for example, a token that uniquely identifies the message. To enable the re-use of meta-data about a message across SOAP extensions, WS-MessageData introduces the MessageData header. As new types of message meta-data are standardized it is hoped that they will be placed inside of the MessageData header so as to more easily enable re-use.

This specification also introduces two specific types of message meta-data, MessageId and RefToMessageId. MessageID is used to provide a Message ID, a URI that uniquely identifies a particular message. RefToMessageId allows one message to identify another message it is associated with by providing the associated message's Message ID.
