Content Landscape (Part II)

In the first installment of this micro series I tried to make the point that different content paradigms are here for a reason and that the very fact of life should be accepted, not ignored.

Each paradigm organizes content in its own way, either using a set of tables, a hierarchy of object classes, a tree-like structure, graphs (semantic networks), or just as natural language text.
