Classes, relationships and external links. A schematic representation of classes that were created by the mapping, of their relationships, and of external links is presented in this figure. The great boxes represent classes, while the smaller represent external datasets. In the latter case, a yellow border denotes RDF dataset linked by URIs, a red one denotes web sites linked by URLs.
