Document Rendering
|
|
==================
|
|
|
|
Document rendering involves extracting all raw revision documents from
|
|
Deckhand's database, retrieving encrypted information from `Barbican`_,
|
|
and applying substitution, layering and replacement algorithms on the
|
|
data.
|
|
|
|
The following algorithms are involved during the rendering process:
|
|
|
|
:ref:`substitution`
|
|
-------------------
|
|
|
|
Substitution provides an "open" data sharing model in which any source
|
|
document can be used to substitute data into any destination document.
|
|
|
|
:ref:`layering`
|
|
---------------
|
|
|
|
Layering provides a "restricted" data inheritance model intended to help
|
|
reduce duplication in configuration.
|
|
|
|
:ref:`replacement`
|
|
------------------
|
|
|
|
Replacement builds on top of layering to provide yet another mechanism
|
|
for reducing data duplication.
