Re: [lyo-dev] Multi-valued extended properties

Martin,

You can provide a Collection as the value for an extended property.

	List<String> values = new ArrayList<String>();
	values.add("a");
	values.add("b");
	getExtendedProperties().put(new QName("https://foo#";, "bar"),
values);

All of the values in the Collection will be included in the resulting
Model.

See JenaModelHelper#handleExtendedProperties().   Hope this helps.
