+**This post explains how to edit a Task object with percentageCompleted value.**
+
+_Example:_
+    
+    # generate a Task uri
+    task_uri = OpenTox::Task.task_uri
+    
+    # pass 'task_uri' to become new Task uri
+    task = OpenTox::Task.run("Message", "Creator", task_uri) do |t|
+      
+      # get Task object and fill with metadata
+      t = OpenTox::Task.find task_uri
+      t.metadata
+      
+      run partial code
+      
+      # edit progress
+      t[RDF::OT.percentageCompleted] = "25"
+      t.put
+      
+      run partial code
+
+      # edit progress
+      t[RDF::OT.percentageCompleted] = "50"
+      t.put
+
+      run partial code
+      "Result URI"
+    end
+    # wait to complete
+    task.wait
+
+**If task status is completed task.percentageCompleted == 100%**
