A Learning flow service supports the management 
and use of complex learning 
scenarios which are more complex than sequencing can support.  It is probable that 
sequencing will be subsumed within learning flow at some point.
The key functions for this service are:
- providing runtime support for learning designs, such as sequencing of activities 
including for collaborative activities
 
Specifications with applicability in this 
area are:
- IMS Simple sequencing
 
- IMS Learning Design
