SIF 3. 0 Environments, Zones & Contexts Melbourne Developer’s Workshop November 2013 Presented by: Joerg Huber

2 Overview ¡ ¡ What is an Environment? What is a Zone? l l ¡ What is a Context? l ¡ Compare it to SIF 2. x Zone Default Context How do these relate to each other? l Do I need all of these? Melbourne MCG: SIF 3. 0 - Env. , Zone & Context November 2013 © Systemic Pty Ltd

3 What is an Environment? The “SIF 3. 0 Environment” the totality of every service the Consumer might possibly provision itself to access. Based upon authentication constraints however, the Consumer’s access to some services it can see might be restricted. It is provided by: ¡ Provider in a direct Environment ¡ Environment Provider in a brokered Environment Holds mainly ¡ Service URLs scoped for each zone ¡ Access Rights for each Service scoped for each zone Melbourne MCG: SIF 3. 0 - Env. , Zone & Context November 2013 © Systemic Pty Ltd

4 What is a Zone? – Consumer’s Point of view An Environment has 1 or Many zones! ¡ There is always a DEFAULT Zone. l ¡ A Zone is a collection of Services a consumer has some sort of access to l l l ¡ If no zone. Id is provided in the REST URL then the default Zone is assumed. In SIF 2. x they were a collection of SIF Objects an agents had access to. Access rights are allocated in each zone for each service Context may be assigned to each service. Various types of Services l l l Object Services (Student. Personal, School. Info etc. ) Utility Services (Alerts, Zone Registry etc) Functional Services (i. e. Endo-Of-Year rollover). Melbourne MCG: SIF 3. 0 - Env. , Zone & Context November 2013 © Systemic Pty Ltd

5 What is a Context? – Consumer’s Point of view A Context is an optional Data Model-specific metadata that may accompany a Consumer Request as a way of further scoping and restricting the possible Provider. ¡ There is always a DEFAULT Context for each Service. l ¡ In a zone there can be more than one Provider for the same “SIF Object” as long as they operate in a different context! l l ¡ If no context. Id is provided in the REST URL then the default Context is assumed. Current Students Special Ed Students Contexts are NOT global they apply to a specific Service Provider in a zone Melbourne MCG: SIF 3. 0 - Env. , Zone & Context November 2013 © Systemic Pty Ltd

6 Relationships… ¡ ¡ ¡ A consumer may connect to one or many Environments. An Environment may have many Zones. A Zone may have many services. Within a zone there can be more than one provider for the same SIF Object (i. e Student. Personal) as long as they use a different context. A consumer who creates a SIF Object in more than one Zone or Context may be given more than one Ref. Id for the same Object! l l ¡ One Ref. Id per service it calls for the same object. A service is scoped per environment, zone and context. May sound complicated but most of the time you will operate in the DEFAULT Zone and Context.
