How does rdf refer to rdfs if rdf came earlier?

For example:

rdf:Property a rdfs:Class ;
    rdfs:isDefinedBy <http://www.w3.org/1999/02/22-rdf-syntax-ns#> ;
    rdfs:label "Property" ;
    rdfs:comment "The class of RDF properties." ;
    rdfs:subClassOf rdfs:Resource .

From: https://www.w3.org/1999/02/22-rdf-syntax-ns

The rdf:Property is referring to several things in the rdfs vocabulary, such as rdfs:Class, despite rdf coming to existence earlier (1996?) than rdfs (1998?).

The distinction between the rdf: and rdfs: namespaces is not technical, but has more to do with the work of two separate working groups at W3C creating the RDF specifications. Mind you, membership in these groups overlapped considerably, as did their timelines.

Having two separate namespaces has been nothing but trouble, we should have gone with just one.
