The source code , with store and SPARQL to retrieve, and a few explanations, is here: https://github.com/jmvanel/semantic_forms/blob/master/scala/forms/src/main/scala/deductions/runtime/semlogs/TimeSeries.scala#L27
The trick used is to create a new URI for each modification of the main database ( find http://localhost:9000/ldp/1486136803523-89228787433384#1486136808956 in the source code ) , that is used both as a subject for metadata, and as a graph for the current modified triples. It deserves more explanations I think.
