Question

I use JGraph for Java to create graphic representation of Petri net and then export it to XML. Is there any method, which add to xml my own text? I need to create there something like metadata, specifically, who created network, when and so on.

You can store some data in parent node (note that this is untested):

((mxCell) ((mxGraphModel)graph.getModel()).getCell("0") ).setAttribute("tagname", "your");

If storing one string is enough for you, this definitely works:

((mxCell) ((mxGraphModel)graph.getModel()).getCell("0") ).setValue("your text");
String text = (String) ((mxCell) ((mxGraphModel)graph.getModel()).getCell("0") ).getValue();
