The larger or more complex a service composition, the more context information will generally need to be managed because more services and inter-service data exchanges will be involved in the corresponding service activity. There are two categories of context information: • context data • context rules Context-related information is one of three state information types, the other two being session and business information. State information types are of relevance to the application of the Service Statelessness design principle. The term "context" (in association with state management) originated from the WS-Coordination specification that established a context management framework for Web services.
