	Title		: Simple Workflow Access Protocol (SWAP)

A standard protocol is needed to integrate work providers, asynchronous
services, across the intranet/internet and provide for their interaction.
The integration and interactions consist of control and monitoring of the
work.  Control means creating the work, setting up the work, starting the
work, stopping the work, being informed of exceptions, being informed of
the completion of the work and getting the results of the work  Monitoring
means checking on the current status of the work and getting a history of
the execution of the work. The protocol should be light weight and easy to
implement, so that a variety of devices and situations can be covered.
 
The Simple Workflow Access Protocol is a proposed way to solve this problem
through use of HTTP protocol, and by transferring structured information
encoded in XML.  A new set of HTTP methods is defined, as well as the
information to be supplied and the information returned in XML, that
accomplish the control of generic asynchronous services.  This has
applicability to workflow because a workflow is itself an asynchronous
service, and it also has the need to be able to call asynchronous services
aoutside of itself.

Send a message to:	mailserv at ietf.org.  In the body type:
	"FILE /internet-drafts/draft-swenson-swap-prot-00.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
