Abstract

Open Data Kit (ODK) is an open-source, modular toolkit that enables organizations to build application-specific information services for use in resource-constrained environments. ODK is one of the leading data collection solutions available and has been deployed by a wide variety of organizations in dozens of countries around the world. This paper discusses how recent feedback from users and developers led us to redesign the ODK system architecture. Specifically, the design principles for ODK 2.0 focus on: 1) favoring runtime languages over compile time languages to make customizations easier for individuals with limited programming experience; 2) implementing basic data structures as single rows within a table of data; 3) storing that data in a database that is accessible across applications and client devices; and 4) increasing the diversity of input types by enabling new data input methods from sensors. We discuss how these principles have led to the refinement of the existing ODK tools, and the creation of several new tools that aim to improve the toolkit, expand its range of applications, and make it more customizable by users.
