	The goal of DataShop web services is to provide a way for researchers with a background in programming to enable their program or web site to retrieve DataShop data and (eventually) insert data back to the central repository. We've created the start of such a service--right now, the service allows you to authenticate with DataShop, and retrieve metadata about datasets and samples in DataShop. Coming next will be the ability to retrieve transaction and step-level data.		As a researcher (EDM, M&M, CMDM), I want to use DataShop's web services to get information about what datasets and samples are available, so that I can retrieve transaction or step-reollup data programmatically from DataShop.

			==== Logging Activity ====

			The Logging Activity report provides a logging diagnostic by displaying counts of all recent log messages received by the logging server, organized by dataset and student session. It is intended for use by technical researchers or staff who are in the process of verifying logging activity from a study site.

Would help in analyzing the reasons for ragged curves and in improving a cognitive model. Probably, it would not be hard to do the same analysis in Excel, after a Data Shop export, assuming that each line in the Excel indicates the skill-opportunity-number. So – maybe that argues against implementing this in the Data Shop."		* "Being able to easily go from a data point in a learning curve to a list of the problems (could be only a single problem!) or problem steps that produced that point.
