Overview
NORDUnet Network inventory project is divided in to three parts. One part that gathers the data (producer), another part that uses the data (consumer) and a repository for the raw data.
Producer
For the producer we use the NERDS projects (https://github.com/fredrikt/nerds) JSON format to save the data. How to actually collect data depends on what you want to collect data from.
Consumer
The only NORDUnet consumer today is NOCLook (http://git.nordu.net/?p=norduni.git) which is a web gui made with the Django web framework and Neo4j graph database as backend for the inventory data model.
