AggData – data sets. for example a set of AggData to describe countries would be a list of every country in the world

AggData is short for aggregate data, which means a set of data that is collected together in one place. On this site, the AggData will come in the form of a list of records, where each record has details about a specific object in the group. For example, a set of AggData to describe countries would be a list of every country in the world, perhaps with details such as capital city, land area, population, and so forth. The raw data might look like the following:

Afghanistan, Kabul, 647,500 sq km, 31,056,997
Albania, Tirana, 28,748 sq km, 3,581,655
Algeria, Algiers, 2,381,740 sq km, 32,930,091
…

and so on. While this information is already publicly available on the web, the advantage of AggData is that the data is collected into one file that is very raw and portable, which makes it easy to integrate into any application or website.
