Open Data Kit (ODK) (http://code.google.com/p/open-data-kit/) is an open-source mobile data collection toolkit for the citizen science, public health, and environmental monitoring. ODK developers (and Change members), Yaw Anokwa and Carl Hartung have just released ODK Collect v1.1 (http://is.gd/4wPW9), an Android client which renders a form, survey, or algorithm into prompts that support complex logic, input constraints, repeating questions, and multiple languages. Some of the new features include barcode scanning, image/audio/video capture and playback, editing of saved forms, and device metadata (phone number, IMEI, IMSI) support.
