The Web Data Principles are a simple set of guidelines about how to make structured information more useful on the Web. The Web Data Principles are a set of simple principles and patterns, and not a specific set of technologies. For a much more detailed set of recommendations, you might want to check out the W3C's "Data on the Web Best Practices" document

The Web Data Principles are more liberal than the 5-star model of Linked Data, which makes specific statements about required technologies. In addition, the Web Data Principles do not propose a hierarchy of stars. Each star can be awarded individually, and it is thus up to the providers of Web Data to decide which of the five principles they are following.
