Aaron, geoff, hiroki and i had a good discussion about how to get PO- 
Trunk steps persisting learner data. The method that we want to  
explore is passing an OTrunk object into the pasStep and bypassing the  
rim/sock/pod model. After that discussion Hiroki, Geoff and I sat down  
and looked at our main scenario for persistence which is notes. i  
think one of the we are confused about is how our sock/rim model  
translates to this OTrunkTransferObject that is passed in.

for instance, in our current model. there is a bean property on Notes  
that is a Map of ResponseDeclarationsToRims. this is created at author  
time. On start up of the step, that map is iterated and the rim is  
used to find its sock. once the sock is found or a new one is created  
it is put into a map ResponseDeclarationsToSocks. this is basically   
mapping the the question to the answer.

i think the big question is this OTrunkPasTransferObject. How do we  
distinguish which data(a sock or OTrunk equivalent) goes with  
question. In our old model a 3 part note has 3 rims and 3 socks.  are  
there OTrunk mechanisms that the transferObject can use? we are still  
going to need some mapping similar to ResponseDeclarationsToRims/ 
OTObject at author time? are there any examples that we can look at?

thanks
