+=== Load local data

+The same approach may be used for accessing your own data (e.g. in `csv` or `json` format) stored within your application directory. You need to include the file within the app package description `....pml` file as:
+{{{#!xml
+<Resources>
+    <File name="data.csv" src="data" />
+</Resources>
+}}}
+and load it in a Python box with correct path
+{{{#!python
+import csv

+class MyClass(GeneratedClass):
+    def __init__(self):
+        GeneratedClass.__init__(self)
+        self.folderName = os.path.join(self.behaviorAbsolutePath(), "..")
