WS-CAF: Contexts, Coordination and Transactions for Web Services [chapter]

Mark Little
On the Move to Meaningful Internet Systems 2007: CoopIS, DOA, ODBASE, GADA, and IS  
We'll also consider how the architecture defined by WS-CAF fits into the evolving architecture of Web services and give an indication of where we think things are going in the future.  ...  There is considerable discussion in the Web services community about how to create composite applications for business process automation.  ...  An implementation of WS-CAF can start with WS-CTX for simple context management, and later add WS-CF for its additional context management features and context message delivery guarantees, and finally  ...

The Influence of an External Transaction on a BPEL Scope [chapter]

Oliver Kopp, Ralph Mietzner, Frank Leymann
2009 Lecture Notes in Computer Science  
The WS-Coordination framework deals with (external) transactions between Web services and is used to define the transaction behavior between a BPEL process and its partners.  ...  The Business Process Execution Language is the dominant standard for modeling and execution of business processes in a Web service environment.  ...  Besides WS-Coordination, the business transaction protocol (BTP, [19] ) and the Web Services Composite Application Framework (WS-CAF, [20] ) are relevant.  ...

A framework for ensuring consistency of Web Services Transactions based on WS-BPEL

Shan-liang Pan, Ya-Li Li, Wen-juan Li
2011 International Journal of Modern Education and Computer Science  
WS-BPEL [1] as a primary web service composition description language, which couldn't coordinate these web service transactions that distribute in a distributed computing environment reach consistent agreement  ...  This paper proposed two kinds of transaction types and coordination mechanisms by analyzing the features of WSC transaction, and a transaction processing coordination model based on BPEL was lastly proposed  ...  Web Services Transactions specifications [8] , Business Transaction Protocol (BTP) [7] , and WS-CAF [9] [10] [11] .  ...

Seunglak Choi, Hyukjae Jang, Hangkyu Kim, Jungsook Kim, Su Myeon Kim, Junehwa Song, Yoon-Joon Lee
2005 Lecture Notes in Computer Science  
For efficiently managing Web Services (WS) transactions which are executed across multiple loosely-coupled autonomous organizations, isolation is commonly relaxed.  ...  A Web services operation of a transaction releases locks on its resources once its jobs are completed without waiting for the completions of other operations.  ...  There are three proposals for protocols to extend the WS with transaction processing capabilities, i.e., Web Services Transactions specifications [6] , Business Transaction Protocol (BTP) [7] , and WS-CAF  ...
