Welcome to ODK

Open Data Kit (ODK) is a suite of tools to help organizations collect, aggregate and visualize their data. Our goals are to make open-source and standards-based tools which are easy to try, easy to use, easy to modify and easy to scale. To this end, we are proud members of the OpenMobile Consortium, the OpenRosa Consortium, and active participants in the JavaRosa project.

ODK tools used all over the world and ODK Collect is our most popular. Below is a demo video that demonstrates some of its core functionality. There is also an IEEE Computer paper, University Week article, a slides, and a project video that discusses our work and a ugrad/grad class at UW-CSE about ODK.

Below is a quick overview of the tools we currently have available.

ODK Collect

ODK Collect is powerful phone based replacement for your paper forms. Collect is built on the Android platform and can collect a variety of form data types: text, location, photos, video, audio, and barcodes.

ODK Aggregate

ODK Aggregate provides a ready to deploy online repository to store, view and export collected data. Aggregate is currently implemented on Google App Engine and enables free hosting of data on Google's reliable infrastructure.

ODK Manage

ODK Manage maintains a database of all phones in a deployment to enable remote device management. By sending an SMS to a deployed phone, Manage can trigger the transfers of forms, data, and applications.

ODK Validate

ODK Validate ensures that you have a OpenRosa complaint form -- one that will also work with all the ODK tools.

ODK Voice

ODK Voice facilities mapping XForms to sound snippets that can be played over a "robo" call to any phone. Responses are collected using the phone's keypad (DTMF) and are automatically aggregated.

If you have questions about ODK, read the frequently asked questions, then ask on the mailing list. We also regularly update our software roadmap with upcoming features. If you'd like a feature that is not on the roadmap, file a feature request.

We are still building more ODK tools and we need your help! The code is easy to work with so checkout the source and have fun. If you have any questions, ask on the mailing list. If you find bugs, be sure to file a bug report.

ODK's core developers are from the University of Washington's Computer Science and Engineering department and members of Change, a group at UW exploring how technology can improve the lives of underserved populations in the developing world. ODK is possible thanks to generous support from Google.
