 As a rule of thumb: Whenever you pass the ''ClientState''-Object into a dms.*-call, all necessary ACL- and Workspace-Assignments should be set automatically by DeepaMehta. This happens because the information which "User" is currrently active in which "Workspace" is part of the Session-Cookie.

+==== Constructing a composite (complex) topic object imperatively ====
+
+One way how i often create new, complex topic instances, in three steps: 1) CompositValueModel, 2) TopicModel, 3) Topic
+
+{{{
+// create the CompositeValueModel
+CompositeValueModel fileComposite = new CompositeValueModel();
+// build it up according to your model
+fileComposite.put("org.deepamehta.moodle.filename", filename);
+fileComposite.put("org.deepamehta.moodle.filepath", filepath);
+// create a new TopicModel
+TopicModel fileModel = new TopicModel(MOODLE_FILE_URI, fileComposite);
+// finally create the new topic instance (with proper ACLs)
+Topic moodleFile = dms.createTopic(fileModel, clientState);
+}}}
