In RDF, the values of a property (e.g., skos:narrower) for a given
subject form a set. So, there's no way (in RDF) to determine an
intrinsic order of two concepts, given only that they are narrower than
another concept.
The lists used in the proposed skos:Array structure avoid this problem
by introducing extra nodes.
This:
thes:001 a skos:Concept
; skos:subArray
[ a skos:Array
; skos:members ( thes:002 thes:003 )
]
.
Is actually short-hand for:
thes:001 rdf:type skos:Concept.
thes:001 skos:subArray _:a.
_:a rdf:type skos:Array.
_:a skos:members _:b.
_:b rdf:first thes:002.
_:b rdf:rest _:c.
_:c rdf:first thes:003.
_:c rdf:rest rdf:nil.
