Prototype service event subscription UI & runtime

[mdutoo]

Service event subscription allows to subscribe to a "listened" service and register on it services that will be triggered on each call.

runtime study

study alternatives of how it may trigger registered services :

• monitoring proxy's event handlers (see wiki),
• FraSCAti Intents,
• FraSCAti business components

  web application allowing users to manage their subscriptions

• first evaluate a few RoR-like frameworks for this goal and choose one. DONE : study on wiki, first tries using play
• study authentication alternatives and choose one. DONE : study on wiki, done using OAuth 1.0
• prototype this web application using the chosen RoR-like framework. DONE views : login / register, registry services list, service details, subscribe, list user subscriptions
• TODO doc in wiki how to deploy and start it / use it in development, TODO in production

  runtime single proxy prototype

• TODO write a MapSubscriptionEventHandler that, when listening a service call, looks this service's url up in a map to find the list of services to call, and write a JAXRS service that updates this map using an array of array (use @XmlElement & other JAXB annotations)

  exemples

• TODO in FraSCAti, write a PrintService.print(String s), write the "glue" PrintAdaptorPAFImpl that implements the PAF interface by calling the PrintService, use it to test the MapSubscriptionEventHandler
• TODO add a notifications table to the SubscriptionApp, display it in the UI, allow it to be updated using a REST service, write the "glue" SubscriptionAppNotificationAdaptorPAFImpl, use it to test the MapSubscriptionEventHandler
• TODO others : tech console, scheduled ping, business db in FraSCAti

  runtime in FraSCAti Studio

• study (and list questions to ask to INRIA) how to port it in FraSCAti Studio : 1. the eventhandler on its own as a mere composite template instanciated from the SubscriptionApp, 2. within our monitoring proxy as a composite template
