In a sense, the form "1;2" is a serialization of the Point > dataclass. In the real world, there can be many different point objects that have a value of (1,2). If you are drawing an X-Y plot you may need to figure out some way to make them appear slightly different, for expository purposes. You don't want your RDF graph to inadvertently assert that these points are the same points if they are not (and yes, I know that it could be considered a nice philosophical question whether they are "really" the same, but let's not enter in that here).
