Thread:Talk:Semantic Maps/Displaying multiple results on a single marker

I am struggling with formatting an output that will show me multiple entries on a single marker. I have multiple events (wiki pages) occurring at the same location and thus they have the same coordinates, but when clicking the marker on the map only one event is shown. I have tried both Google Maps v3 and OpenLayers and neither format seems capable of this. Marker clustering does not help either as the cluster does not show data when clicked. is there any way I can display multiple matching pages for a single coordinate?
