A simple CCOW context manager with no persistence.
UPDATE JUNE 2016
This is an implementation in nodejs of a few of the interfaces in the HL7 CCOW specification. Its purpose is to provide a functioning (and simple) ContextManager.
NB: Current status is a very rough implementation - not suitable for production.
Currently the ContextManager manages a single context and the following kind of flow is supported (CP is ContextParticipant and CM is ContextManager):
CP ==> JoinCommonContext(applicationName,<contextParticipant>) ==> CM CP <-- OK, participantCoupon <-- CM CP ==> StartContextChanges(participantCoupon) ==> CM CP <-- OK, contextCoupon <-- CM CP ==> SetItemValues(itemNames, itemValues, contextCoupon) ==> CM ... CP ==> EndContextChanges(contextCoupon) ==> CM CP <-- noContinue, responses <-- CM CP ==> PublishChangesDecision(contextCoupon,decision) ==> CM CP <-- listenerUrls (web-application case) <-- CM ContextChangesAccepted (CM ==> all other CPs) ... CP ==> LeaveCommonContext(participantCoupon) ==> CM CP <-- OK <-- CM
coffee-script and installation is then mostly easily done with
$ npm install -g coffee-script ... $ npm install -g ccow.contextmanager ...
ctxmgr command which starts a server on port 3000.
Now returning a
noContinue: [boolean] responses: string
Current status is a basic implementation of ContextManager, ContextParticipant and ContextData interface.
