The software application DiversityNaviKey (DNK) is a tool primarily designed for diagnosis and interactive identification of organisms or other items as well as item groups which are part of or related to biodiversity, geodiversity or environmental research, by means of a set of pre-defined characteristics. It allows for sophisticated selection based on highly structured data sources (datasets) with descriptive data (trait data with descriptors, descriptor categorical states, descriptor values). The browser-based tool is optimized to build and run determination keys based on the consecutive selection of descriptors, descriptor states and values during the identification process.

The new application is realised as a „Progressive Web Application (PWA)“. Thus, it is platform independent and is running on every common browser (Firefox, Chrome, Edge, Safari). The pages are responsive and adjusted to the user device (desktop, tablet, smartphone). By using caching mechanism of modern browsers, like ServiceWorker and IndexedDB, the main tasks of the application will also be available in offline mode.


DiversityNaviKey is using SDD structured data sources offered via PostgreSQL cache database mechanisms and REST web services as established for DiversityDescriptions. It is the reimplementation of the well-known multi-lingual java applet/application NaviKey which is also an integrated part of the DiversityNavigator database client.



DiversityNaviKey will be presented at the INFORMATIK 21 Konferenz Berlin & online, Workshop Computer Science for Biodiversity. Future extension to cover DiversityMobile functions is envisaged. DiversityNaviKey might also become part of the wider NFDI4Biodiversity tool network.




Six exemplary data sources which will be available for diagnosis and identification via DiversityNaviKey starting with October 2021

The data sources come from different scientific fields (botany, mycology, lichenology, bacteriology, chemistry, sociology). The by far largest dataset is that on lichen trait data provided by the long-term information system LIAS.

BFLheilpflanzendesc (•••) Artenquiz zum Thema Heilpflanzen in Bayern Das Wissen über die rund 300 in Bayern vorkommenden Heilpflanzen und vor allem die Fähigkeit sie in der Natur zu erkennen geht immer mehr verloren. Dabei finden sich in vielen Pflanzenarten wertvolle medizinische Wirkstoffe. Auch sind sie gar nicht so selten zu finden. Im Artenquiz "Heilpflanzen in Bayern" unter http://artenquiz.bayernflora.de/ können Sie sich zum einen selbst testen und sehen wie gut Sie die verschiedenen Heilpflanzen bereits erkennen, zum anderen können Sie sich durch genaues Betrachten der Bilder und Auswählen der richtigen Merkmale neues Wissen aneignen. Der Datenbestand wird in DiversityDescriptions gemanagt. Hagedorn, Gregor; Plank, Andreas; Leininger, Iris; Link, Anton CC BY ...

DEEMY An Information System for Characterization and DEtermination of EctoMYcorrhizae DEEMY is collecting descriptive data on ectomycorrhizae. The data are stored in DiversityDescriptions. The online output of the database offers definitions of the descriptors (characters) of ectomycorrhizae used, morphological descriptions of the ectomycorrhizae, original hand drawings and photographs. Currently, DEEMY is comprising more than 500 types of ectomycorrhizae characterized by 498 often multi-state descriptors (characters). It includes more than 850 drawings of characters and 177 images of ectomycorrhizae (http://www.deemy.de/).

DSMZbacdivedesc (••) Mobilisation of data for GFBio services - Bacterial Descriptions Use Case The description of five comprehensively annotated bacterial strains have been imported into the DiversityDescriptions in the course of the project GFBio (www.gfbio.org). The purpose of this mobilization is the availability of taxon-related descriptive information for the GFBio data portal following various standard schemas, e.g. SDD, for the test and development of data pipelines and work flows. The data has been manually annotated out of species descriptions derived by results of recently completed and ongoing projects carried out and published by researchers at the DSMZ. The ecological and environmental relevance of these strains is given by their participation in nitrogen and carbon cycles (significant exoenzyme activity) within their particular habitat. The detailed documented metabolic and physiologic profile of each strain indicates their significant adaptation to the soils of different climates. Hence, these strains are important biotic components of their environment.
