>represents a single tag or keyword. Each tag has a unique URI. Equal tags (e.g. "san francisco" and "san fran") can be semantically related via the sameTag property. Semantic relations, such as broader and narrower terms (e.g. "blue" is kind of "color"), can be expressed with the SKOS core ontology (e.g. http://www.w3.org/2004/02/skos/core#broader). Therefore Tag is a subclass of SKOS core Concept.</rdfs:comment>

>Denotes the concept of a tagging: a Tagging consists of at least the basic tuple {tagger, resource, tags}. All other properties are optional. Furthermore Tagging follows the ValuePartition pattern, which means that it can only have values from either PublicTagging, PrivateTagging or ProtectedTagging.</rdfs:comment>
