Hi Stephen, yes sorry should have been more plain
a term can have a Prefered Term (PT), many Broader Terms (BT), Many Narrower Terms (NT) Related Terms (RT) etc So User supplied Term is say : Ski Prefered term: Skiing Broader terms could be : Ski and Snow Boarding, Mountain Sports, Sports Narrower terms: down hill skiing, telemark, cross country Related terms: boarding, snow boarding, winter holidays Michael, yes exactly, SKOS, although maybe without the over wheening ambition to take over the world. By the sounds of it though out of the box you get a simple (but pretty effective synonym list and ring) Anything more we'd need to write it ourselfs ie your thesaurus filter and plus a change to the response as broader terms, narrower terms etc would be good to be suggested to the ui. No plugins out there ?
