Hi,using the above sparql statement,i get the following result,
now i want to grouping them using "move" and ordering using "submoveslice",then get the result : <u:move11> -<u:road1><u:road1><u:road2><u:road3> and <u:move22>-<u:road2><u:road3><u:road1><u:road3>,how to?
Just to clarify. say we group by ?move variable, then do you want to perform some kind of aggregation on ?road variable?
From what yo described, looks like you want to concatenate all the road URIs for each ?move variable.
