A topic with which this thing is associated.

The intention of this property is not to describe the contents of a thing, but rather to scope out, by associating it with relevant topics, who might be interested in it (for example, those who have the assoicated topic as a topic of interest). The range of this property is not formally defined, but Categories and Tags are recommended.

defines this property as a subproperty of , but this probably isn¦t quite right: While this property does associate a thing with a subject, the association is broader than “aboutness” would imply. This ontology accordingly keeps the properties separate.
