There are a number of domain & range errors in your descriptions of the RDFS properties.  You should check your descriptions against your table "RDF Properties".

Since you provide no definitions, there is confusion about the distinction between "resource" and "instance" and "member".  For example, in the description of "rdfs:type", does the domain of type include individuals, or classes, or both?

In your description of the property "rdfs:object", you imply that Literal is not a subclass of Resource.  That contradicts the definition of Resource.

In many places, you say that x "represents" y.  You should say "denotes" or "means".
The ranges in the "RDF Properties" table encourage the continuing confusion between "Class" and "Resource".  With the exception of "type", the ranges should be "Resource" instead of "Class".  The only consistent definition of "Class" that I can come up with is: "Class" is the set of class names.  Given that definition, the range of "type" is "Class", i.e., a class name.  As I mentioned in a previous email, "not specified" should be replaced by "Resource".
