Hi Annette,

I just made the updates on the BP Provide Subsets for large dataset. Please
let me know if this is ok with you.

New example:

The MyCity transit agency has been collecting detailed data about passenger
usage for several years. This is a very large dataset, containing values
for numbers of passengers by transit type, route, vehicle, driver, entry
stop, exit stop, transit pass type, entry time, etc. They have found that a
wide variety of stakeholders are interested in downloading various subsets
of the data. The folks who run each transit system want only the data for
their transit mode, the city planners only want the numbers of entries and
exits at each stop, the city budget office wants only the numbers for the
various types of passes sold, and others want still different subsets. The
agency created a Web site where users can select which variables are of
interest to them, set ranges on some variables, and download only the
subset they need.

New How to test:

Check that subsets of the dataset can be recovered making smaller requests
or downloading smaller units.

Thanks,
Berna
