Simple aggregation pattern

From Xcri

The Simple Aggregation Pattern is an implementation architecture whereby each provider in the network offers an XCRI-CAP feed, and aggregators acquire the feed using a simple HTTP GET request. Aggregators can request feeds using a scheduling system. The aggregator replaces any previous information about the provider and their courses with the latest data.

This is the implementation pattern used by the pilot projects and the XCRI Aggregator.

Each provider in the Simple Aggregation Pattern need only implement XCRI Using a static XML file. However, it also potentially supports using Multiple feeds for one provider.
