To add to the picture for accessing collections:
http://www.w3.org/2001/sw/DataAccess/tests/data/BuiltInProperties/
gives examples using a different approach specifically to accessing
collections using properties with specific meanings.
SELECT ?x ?member
{ ?x :p ?list .
?list list:member ?member .
}
list:member matches over the members of list ?list.
Implementation experience:
http://jena.sourceforge.net/ARQ/extension.html#propertyFunctions
and also that users expect the members of a collection to come back in the
order they are in the collection.
