The FAIMS Mobile Platform (http://www.fedarch.org) is an open source, generalised system for digital data collection on Android. It works offline and helps record free text, multimedia, structured or spatial data with ample opportunity for the capture of metadata and certainty components of the captured data. It needs to be customised (via an xml definition document) for particular field/lab workflows. As a server-client system it facilitates simultaneous operation by multiple users. It’s great for large teams operating in degraded network, or entirely offline, who need to generate consistent and complete digital datasets.
