Hello Lorenz, I have assigned the value to team1 but mistakenly typed only
team.
The Chris Dollin comment about "*setPropertyValue is /documented/ as
deleting any previous value **for that property" *
*makes sense but if I write *
team1.addLiteral(goals, p), in place of team1.setPropertyValue(goals, p)
then it saves new data and the previously saved data is also there.
