1. Purpose of this Repo#

Status#

Approved

Context#

OEP-26 consists of the following components:

  • Asynchronous Routing Backend

  • Regular-expressions based filter processor

  • IMS Caliper transformer

  • xAPI transformer

  • Router to forward events

Keeping all of these components in one repo will make the repository unnecessarily tangled since these additional components are not required by the core app for its functionality.

Decision#

Among the components listed above, Asynchronous Routing Backend and the regular-expressions filter will be added in the core app (i.e. event-tracking) while the other components, i.e. Caliper transformer backend, xAPI transformer backend and router, will be added in the current repo.

By keeping the concrete backends separate from the code, we can have only the core plugin interface for event tracking in its repository.

Consequences#

The code will be decoupled and components can be used independently if required.

Rejected Alternatives#

Add the routing backends to the event-tracking repository

This idea was rejected to keep the core event-tracking repository clean and independent. The core repo is functional on its own and any pluggable extensions should be implemented separately.
