-      <span property="rdfs:comment">Schema.org's notion of 'Topic' covers categories, controlled lists of values, subject classification codes (e.g. UDC, Dewey), thesauri and other controlled codes. This mechanism is not intended as a general-purpose knowledge representation system. In schema.org a Topic code (typically published at some url, eg. using W3C SKOS) can be used to express what a creative work is 'about', but also it can be used with the occupationalCategory of a JobPosting, amongst other properties. For example, the targetUrl of an AlignmentObject can also be used in this way, when describing educationally-oriented resources. 'Topic' in schema.org corresponds to 'Concept' in W3C's SKOS language.</span>
