Just across the wire [1] - a new Web Services framework called "WS-CAF":
<Excerpt>
A draft set of specifications for the Web Services Composite Application
Framework (WS-CAF) has been published by Arjuna Technologies Limited,
Fujitsu Software, IONA Technologies PLC, Oracle Corp and Sun
Microsystems. WS-CAF is an "open, multi-level framework for standard
coordination of long-running business processes across multiple,
incompatible transaction processing models and architectures. WS-CAF is
compatible with current related specifications and does not require the
implementation of a new transaction protocol."
</Excerpt>
This framework appears to overlap with several aspects of GXA (Global
XML Web Services Architecture), of which OASIS WS-Security is a part.
The following three specifications comprise WS-CAF:
(1) Web Service Context (WS-CTX):
A lightweight framework for simple context management that helps enable
all Web services participating in an activity share a common context and
exchange information about a common outcome.
(NOTE: This appears to be similar to the "coordination context" that is
passed between message exchange participants as part of GXA's
WS-Coordination specification)
(2) Web Service Coordination Framework (WS-CF):
A sharable mechanism that manages context augmentation and lifecycle and
provides the notification of outcome messages to Web services
participating in a particular transaction.
(NOTE: This appears to be similar to the general nature of GXA's
WS-Coordination and WS-Transaction specifications)
(3) Web Services Transaction Management (WS-TXM): Comprised of three
distinct, interoperable transaction protocols that can be used across
multiple transaction managers. WS-TXM supports multiple transaction
models to help enable participants to negotiate outcomes with each other
and make a common decision about how to behave, especially in the case
of failure, regardless whether the execution environment is CORBA,
Enterprise JavaBeans (EJB), .NET, Java Message Service (JMS), or some
combination.
(NOTE: In addition to GXA's WS-Coordination and WS-Transaction
specifications, this appears to have aspects that are similar to GXA's
WS-ReliableMessaging specification)
