"""This module implements the data export renderer.
The data export renderer is a way of exporting structured data from Rekall. The
renderer is based on the JsonRenderer but has a different goal - while the
JsonRenderer is designed to be able to exactly recreate the objects in the
future the data export renderer aims to include useful information about
exported objects.
For example, in order to decode the JsonRenderer output one must have access to
the original image, since the decoder will generate the exact BaseObject()
instances that the encoder used.
Not so with the data exporter - the exported data contains a lot of additional
information about the exported objects. The exported data also omits information
which is not relevant without access to the original image.
