Aristotle-MDR is an open-source metadata registry as laid out by the requirements of the ISO/IEC 11179:2013 specification.

Aristotle-MDR represents a new way to manage and federate content built on and extending the principles of leading metadata registries. The code of Aristotle is completely open-source, building on the Django web framework and the mature model of the 11179 standard, allowing agencies to easily run their own metadata registries while also having the ability to extend the information model and tap into the permissions and roles of ISO 11179.

By allowing organisations to run their own independant registries they are able to expose authoritative metadata along with the governance processes behind its creation, and by building upon known and open systems agencies, can deliver a stable platform for the sharing of metadata.

Aristotle-MDR aims to be compliant to the core model described within ISO/IEC 11179, however a number of extensions are available to extend functionality and add additional content types.

1. Add "aristotle_mdr" to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = (
       ...
       'haystack',
       'aristotle_mdr',
       'grappelli',
       ...
   )

   To ensure that search indexing works properly haystack must be installed before aristotle_mdr. If you want to take advantage of Aristotle's access-key shortcut improvements for the admin interface, make sure it is installed before grappelli.

2. Include the Aristotle-MDR URLconf in your project urls.py. Because Aristotle will form the majority of the interactions with the site, and the Aristotle includes a number of URLconfs for supporting apps its recommended to included it at the server root, like this:

   url(r'^/', include('aristotle_mdr.urls')),

3. Run python manage.py migrate to create the Aristotle-MDR Database.
4. Install lessc for your system (eg. apt-get install node-less) or configure django-static-precompiler to use your LESS pre-processor of choice. (This step is not required if you are running from PythonAnywhere)

5. (Optional) Compile the multilingual resource files for improved performance, like so:

   django-admin.py compilemessages

6. Start the development server and visit http://127.0.0.1:8000/ to see the home page.

For a complete example of how to successfully include Aristotle, see the tests/settings.py settings file.

A live Aristotle-MDR instance is available for review on PythonAnywhere at: http://aristotle.pythonanywhere.com/. Be aware, this is an active development instance and may sporadically be unavailble.
