RDF Schema vs. DAML+OIL vs. OWL: A Comparison.

Topic Maps und RDF: Living with 'em (by Lars Marius Garshol).

"For someone looking into topic maps and RDF today the similarities between them are obvious, and it may appear absurd that users should be forced to choose between two technologies that to them must seem almost indistinguishable."

"[I]t wasn't before early 1999 that the two communities started to become aware of one another, and by that time it was already too late."

"The concept of reification has had the misfortune to have had stuck onto it a rather intimidating name [...]"

"RDF Schema is relatively simple, and allows the definitions of two kinds of things: classes and properties. Both may be assigned a label and a comment as documentation. Classes may have superclasses, and properties may have domains (the allowed classes of subjects) and a range (the allowed class of the object). There are a few more features in RDF Schema, but this is the heart of it."
