topicmapsforge.org publishes a topic map on the descriptive variety lists of Germany's Federal Authority for Plant Varieties (Bundessortenamt).

The map, available in German only, provides access to data on plant varieties published in the German variety lists (Beschreibende Sortenlisten). It is a show-case produced with agreement but without participation of the Bundessortenamt, and is not meant for productive or commercial use.

The web application rendering the topic map on plant varieties offers a greatly increased number of access paths to information in the descriptive variety lists. Compared to the web interfaces provided by the Bundessortenamt, it also offers added functionality not only on the assortment tables, but also on a large number of overviews not available via the authority's website.

The latter including breeder related overviews but also variety distributions over the evaluated properties such as susceptibility to mildew in the listed varieties of common winter wheat. Moreover, a hierarchy-browser allows navigation on property-types, thus offering overviews such as the variety distributions of common winter wheat over the evaluated disease susceptibilities .

Due to the underlying subject-centric information architecture, data is upgraded to a highly interconnected, and navigable network of subjects. Information on each subject is collocated around the very subject itself, and available at the cost of a single mouse click.

The topic map and the web application provided on topicmapsforge.org render the wealth of information in the German variety lists navigable, much more transparent and accessible in an efficient and intuitive way. Try it out - so you know.
