A computed property (also known as property functions or magic properties) is a predicate that occurs in a SPARQL query pattern with matching semantics other than simple subgraph matching. One common example use case for this is providing a predicate that relates an RDF list subject to the member items of the list. Another common example is providing a computed property that relates string literal subjects to free-text (a la Lucene) search strings.
