DataFerrett and TheDataWeb use a sophisticated metadata database that facilitates access to multiple data types, including microdata (individual survey or census records), aggregate data (pre-summarized data), time series data (a measure over time), and longitudinal data (follows a person over time).

TheDataWeb metadata is also the key to allowing for re-use of saved analyses and for the creation of analyses over time using recurring datasets.
