SOAP

By AskemosDesign communication (between places) in the Askemos is based on unidirectional asynchronous messages. Soap is web based standard for just that, hence message eachange can be conceptually understood as soap ( http://www.w3.org/TR/SOAP/ ) messages. It's said to be conceptually, because several redundant information (envelope and headers) is not actually generated until it's really needed.

SOAP considered canonical (lambda weblog, still need to read it actually)

Bidirectional (request/response) models can be build on unidirectional messages with easy (and this is what's going to happen). There is not standard yet found, but microsoft is pushing for soap-rp: http://msdn.microsoft.com/library/en-us/dnsrvspec/html/ws-routing.asp?frame=true , which will be taken as base model for the time being.
