Extracting than 100 elements (non repeatable) from the databse accounts 
for substantial.

Costs has nothing to do with the license.

It defines a substantial part in such a way that the extracted part has a large part of the costs (investment) the generation/collection, maintenance, care of the entire database takes. So when collecting all the nodes for a zip code takes 1,000 users and one ear of effort, it might be substantial. However, as we all know, this is not the case. They're just part of the big planet database and vary in quality and effort all over the world. So extracting the zip codes for a small extract of the huge planet file, isn't substantial at all. This is because the maintenance, care and provision of the postal codes costs no more or less than the maintenance, care and provision of the other elements. Also measured by the number of elements, the zip codes only make up a small part (actually, this doesn't matter, since the investment is the important thing).
