Hi Bernd,
to add or remove triples, don't go directly through the TCH graph. That's too
error prone and it's much simpler to do this
let workflowGraph = tbs.queryGraph('workflow_1');
graph.transaction(workflowGraph, 'Adding a triple', () => {
owl.Thing.add(rdfs.seeAlso, owl.Nothing);
});
Which will create the added triple in the given workflow and record it properly
in the change history.
Does this give you enough clues to proceed?
