[IPOL discuss] Demo system source code released

[Miguel Colom]

Dear all,

We're glad to announce that we've released the working source code of  
the whole demo system under a free-software AGPL license.

The system is under very active development, improvement, and  
refactoring, but it's stable enough to publicly release its sources.
Its git repository is here: https://github.com/mcolom/ipolDevel

About the documentation, you'll find in the repository some reference  
manuals on the system architecture, system administration, and also  
the specification of the DDL. About the DDL, we're changing the syntax  
of some parts, and thus it's better that you simply follow the  
"copy-paste" from other working demos instead of following a  
documentation which can change at any moment. Once the documentation  
is stable, we'll release it as several PDF files.

Technically, the demo system itself is a flexible distributed system  
made of isolated micro-service units which communicate through HTTP.  
The web interface is made with JS with AJAX techniques, and the  
Control Panel is a small Django application.

Best,
Miguel
