Subject Re: Supporting content types in Synapse and Axiom
Date Fri, 27 Jul 2007 10:13:57 GMT
One more thought. A number of systems use a java Map message as a core
data type. Especially a Map<String,Object> where Object is actually a
simple type object such as Float, Double, String, Boolean

In particular JMS supports these. I think it would be valuable to
define this as a core Synapse datatype. For example, it would be cool
to be able to mediate between a JMS Map message and another JMS Map
message, and have a well-defined schema for what the Axiom
representation would look like in Synapse.
