Extensible Architecture
- Also Known As
-
- Intent
-
Build flexibility into
the very nature of a system by basing it on
well-defined interfaces and simple interactions.

Nooron benefits
from the Extensible Architecture approach
first by attempting to make as much of
the system as possible be knowledge-based
and then leveraging everything with a
growing set of knowledge-based tools.
For example, PyOKBC is the
Python knowledge
representation API (Application Programmer
Interface) used by Nooron to talk to
data and by the creators of 'garments'
(Nooron Page Templates, nee Zope Page Templates)
which portray and interact with content.
PyOKBC was based on OKBC, the Open
Knowledge-Base Connectivity API because
OKBC was specifically designed to interact
with diverse knowledge sources simultaneously,
interactively and interoperably. Knowledge
basees served by one machine from one
kind of KRS (knowledge representation system)
can do things like inherit from and
transitively contain knowledge from other
machines using other KRSes. The possibility
of using PyOKBC backends to turn legacy
datastores into knowledge stores is hence
the fundamental mode of extensibility in
Nooron.
By using knowledge-based techniques
to generate XML output, Nooron makes
the generation of a vast range of useful
portrayals of knowledge to be possible with
a tremendous amount of generality,
reusability and customizability. Reusability
will be the reward of careful
and diligent authors of NooronPageTemplates.
