Hi Christophe, > Does anyone have designed a way to specify concept ordering when > displaying a tree of concepts? To ensure *any* ordering, the concept scheme must be encoded with http://www.w3.org/TR/skos-reference/#collections > Usually, alphabetical ordering is the best to display narrower concepts > of a given concept. You could also order by number first displaying NTs that have other NRs followed by leafs, or you could order by number of documents, indexed with the concepts, or by skos:notation (if given) etc. But sure, the most common way of sorting is alphabetical - which depends on the language, by the way! I would always assume, that there is no natural order of elements in RDF data unless it is explicitly stated. But using ordering in RDF is a pain in the a**: In most cases you first need to in infer some entailment and do validity checks on the lists. Otherwise your ordering could turn out to be a tree or to have circles!
