OWL2
スキーマ定義のRDF/XML文書においてrdfs:seeAlsoが使われているのは先頭付近の2か所だけ。
それぞれの値はURIであり、ブラウザでアクセスすると人間可読な文書に辿り着く。
Design Principles （一部）
Each class term has a rdf:type and a rdfs:subClassOf triple.
Each property term has rdf:type, rdfs:domain and rdfs:range triple.
There is no use of OWL terms for "defining" other OWL terms, such as "owl:complementOf".
Every term has a rdfs:label, as for the original owl.owl. The same style is used (this is also the same style in rdf.rdf and rdfs.rdfs).
Every term has a rdfs:comment describing this term, mostly by a single sentence. This has been practice for rdf.rdf and rdfs.rdfs, and the style used there has also been basically adopted.
Every term has a rdfs:isDefinedBy, pointing to the namespace document itself. This practice has been adopted from rdf.rdf and rdfs.rdfs.
no mentioning of RDFS annotation vocabulary anymore (rdfs:comment, rdfs:label, rdfs:seeAlso, rdfs:isDefinedBy):
