This ari defines the key abstractions for automatic resource inclusion as well as GraphQL.
This ari defines the key abstractions for automatic resource inclusion as well as GraphQL.
The system is split up into 3 distinct layers:
+---------------------------------------------------------------------+ | Presentation Layer | | GraphQL | Naptime HTTP | +------------------------------+--------------------------------------+ | | | Inclusion Engine | | | +---------------------------------------------------------------------+ | Data fetching | | Local execution | remote execution | +=====================================================================+ | | | Unmodified Naptime APIs | | | +---------------------------------------------------------------------+
A request enters the system via the presentation layer (typically parsed from the network). The presentation layer constructs a org.coursera.naptime.ari.Request and passes that to engine. The engine performs a number of validations against the schema, and then makes a number of requests to to the Data Fetching layer to assemble all of the (available) data required to construct a response. This is passed back to the presentation layer, which constructs a response to be sent out on the wire.
The API between the presentation layer and the inclusion engine is the org.coursera.naptime.ari.EngineApi
The API between the inclusion engine and the data fetching layer is defined by org.coursera.naptime.ari.FetcherApi.
