Various implementation approaches are available for digital field guides and identification tools that are created for the web and mobile devices. The architecture of the “biowikifarm” publishing platform and some technical and social advantages of a document- and author-centric approach based on the MediaWiki open source software over custom-developed, database driven software are presented.

BioPortals are a ‘Google-like’ webportal solution tailored for national or thematic biological diversity information needs. This solution allows for an efficient route to retrieve information from heterogeneous biological information sources after identification with integrated identification systems. BioPortals can be used in combination with mobile devices and provide options to share biological observation data after identification in the field.

The Open Key Editor (OKE) is a tool for editing and enriching existing identification keys and to produce localized ‘minikeys’ that apply to local flora and fauna, such as in parks, nature reserves and school gardens, or keys that apply to a particular season. The minikeys are easier to use than their originals, simply because of the fact that they deal with less species, their language can be adapted to a particular audience (e.g. pupils), and because they always point to species that are known to be present. OKE also allows the inclusion of user-generated content in any minikey (new text, images, hyperlinks etc.). The output of minikeys can be automatically tailored for display on computers, smartphones or PDA’s.

This paper describes a new approach for creating and using identification keys based on two main components: the Open Key Editor and the Open Key Player, both of which were created within the European project KeyToNature. The Open Key Editor can be used to produce custom identification keys starting from a master key and to add original usergenerated content, while the most important feature of the Open Key Player is the possibility to track relevant user activities into an eLearning environment, in order to collect data to improve the design and usability of identification keys.
