View source for Add Problem View to Export and Import

'''Status: Design/Req'ts complete, Estimate 18 days'''

== User Story ==

'''Transaction Export: '''
As a researcher, I want to export a dataset sample with problem view and problem start time values so that I can analyze the problem information on a transactional level.  Previously problem view information was only available in the student step rollup export.<br>
'''Import (tab delim): '''
As a researcher I would like to include problem view and problem start time information within my tab delimited transaction file for dataset import.  Likewise, when creating a new dataset out of a sample of an existing dataset, I would like the problem view and problem start time data to be preserved.  Currently data is lost for Carnegie Learning munged datasets during a transaction export.

== Notes/Comments ==

Transaction Export:<br>
* The aggregator already creates the problem view data contained in the step_rollup table.
* The student problem rollup already produces problem_start_time values. 
* Some Carnegie Learning datasets come with problem_event data and exporting would lose any of that information.  DS680: (Exporting and Importing some datasets causes a loss of data on CL datasets.)
* Voted for feature prioritization at 04/21/2011 team meeting. 

Import (tab delim):<br>
* Infrastructure for storing problem event data already exists for CL datasets.
* DS680: (Exporting and Importing some datasets causes a loss of data on CL datasets.)
* Maintains export compatibility with DS1285: (Feature: Add Problem View and Problem Start Time columns to Tx Export).
* FFI was just released with version 5.0 of DataShop.  We should still be familiar with the implementation to make this change swiftly.
