Biari Workbench Technology Stack
Over the course of developing our Workbench solution we’ve adopted a powerful set of interconnecting components. It’s worth mentioning what these are and how they fit together.
There’s an art to using the right tool for the job, and we’ve made mistakes. We over-used Mako (see Loki’s blog post) and also originally used a slightly inferior lib for the C++ xmlrpc back end; both these mis-steps were fairly easily rectified. Arguably, we probably still use too much C++ and not enough Python – the C++ line count dwarfs the Python line count by a considerable margin. One last interesting point is that, at the moment, we’re still eschewing use of an ORM (Object Relational Mapping layer – such as SQL Alchemy) – time will tell whether that is a good idea or not.
– client-side browser language
– OSM map provider/server
XML – eXtensible Markup Language
Mostly in C++ using STL
– C++ library for unit testing
– map data library, part of GDAL – used to read map data
– C++ back end for XMLRPC – used by a running process to communicate with the front end via Python
