So now you have downloaded at least one dataset, and in previous part you also set up the parltrack no-db console. Now what? how do you know what is in the dataset? For this to answer Parltrack publishes the "schema"s of the datasets on the dumps page. In the table there is a column with a link to the schema for each of the datasets.
