<a href="mailto:cjauvin@gmail.com">Christian</a> writes <i>"I have created <a href="http://surveillance.mcgill.ca/dracones">Dracones, a Python and JavaScript web mapping framework based on MapServer</a>, which I think could be of interest to the open source web mapping/GIS community.
This framework began its life as a surveillance application for Montreal Public Health. After a lot of refactoring sessions, I had the idea of abstracting a set of core client/server services, that would become the framework, and to rewrite the original application in terms of those. Thus the set of features provided by Dracones stems from pre-existing application needs, rather than the opposite.
In a nutshell, here is what Dracones provides. <br> <br>On the client side:<br>
* A lightweight but powerful map widget (100% JS), with state of the art features like AJAX-based smooth scrolling, visual selection and info tooltips<br>* An extension mechanism to define new UI behaviors (e.g. what happens when clicking on the map, or drawing a selection box around objects)<br> <br>On the server side:
<br>* A set of Python classes and functions (written on top of Python-MapScript) that encapsulate the application state, and ease the interaction with its map objects<br>* A well-thought extension mechanism, to define custom requests and queries<br> <br>Dracones also provides a bunch of other application-centric features, like easy map image export and undo/redo. Last but not least, I've been very careful in writing the documentation and tutorials, which I think cover a wide range of issues and possibilities.
This work is still in Alpha stage, and I will be of course very interested to hear the community's comments and suggestions."</i><p><a href="http://industry.slashgeo.org/article.pl?sid=10/01/20/2037236&from=rss">Read more of this story</a> at Slashgeo.</p></div>
