Design Specifications

Below are the ODK tools released and supported: - ODK Build enables users to generate forms - called XForms - using a drag-and-drop form designer. Build is implemented as an HTML5 web-based application and targets the common use case of a simple form. - ODK Collect is a phone-based replacement for the 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 provides a ready to deploy online repository to store, view and export collected data. Aggregate can run on Google's infrastructure as well as on local servers backed by MySQL and PostgreSQL. - ODK Form Uploader uploads a blank form and its media files to ODK Aggregate. - ODK Briefcase transfers data from Collect and Aggregate. - ODK Validate ensures that the users have a OpenRosa compliant form -- one that will also work with all the ODK tools. - ODK XLS2XForm allows XForms to be designed with Excel.
