Supplementary specification ·$a forms URI identity of the concept. ·$d’s value is “01”, which means top concept. If $a is a single class number (i.e. when $c doesn’t exist), it will be converted to the value (object) of skos:notation. If there is no superordinate class number $9, only the superordinate class name $h is recorded, the last $h should be the skos:prefLabel of skos:concept of
