I have been working with the Remote Control feature of Lime Survey to connect the survey tool to another administrative tool which allows me to import questions answers. It is far easier to work with JSON data in PHP for questions responses and it was more useful for me to get completed tokens as compared to incomplete token. After adding these features I also added the ability to only download token and answers after a specific date to limit the amount of data transfered to only new responses since an import date.
Since these are method currently running on my production server I would like to submit them to Lime Survey for consideration in your next release. The necessary files have been attached for your review. Maybe these methods will help other users looking to use a Web Service to import data.
The Methods:
sTokenCompleteJson
sTokenCompleteSinceJson
sGetSurveyResponsesJson
sGetSurveyResponsesSinceJson
