Kiva: Viva Business Information Translation System
While working with C3, we helped develop an entire application for Kiva on top of Drupal that allows volunteers to translate information from any languages to English. Our work mainly involved the workflow system that carried incoming business information through a number of steps leading all the way out of Drupal. The workflow system allows Kiva volunteers to translate businesses in other languages to English.
While developing this application we ran into significant challenges with requirements elicitation. There were also problems with scaling which came mainly from using node reference.
Eventually Kiva decided to move the application in house and they have been working with the application ever since.
In the end we had a falling out with C3, but we're happy to announce that we contributed approximately $4,000 worth of volunteer work to the project.
