This makes it possible to create an interdependent arrangement of learning materials as building blocks for a curriculum. Such arrangements are called learning trajectories. A datamodel is presented in which the entities involved and their relationships are depicted. A first implementation of this is realized and published in September 2010.http://openaccess.uoc.edu/webapps/o2/bitstream/10609/5104/6/Schuwer_2.pdfhttp://openaccess.uoc.edu/webapps/o2/bitstream/10609/5104/6/Schuwer_2.pdfSchuwer_2.pdfBarcelona, Netherlands, Europe
