Get Taxonomic Name Usages Right

[pdatascience]

It is important to get this functionality of the Search-and-Browse interface right. Taxonomic name usages are part of the Taxonomic Concept template in the moment. They need to be moved to a new Taxonomic Name template.

Currently there are some issues

• the database doesn't seem to have full information on taxonomic name usages
• we are not sure whether the information that is in the database is displayed correctly
• it should be possible to click on the individual taxonomic name usages

e.g. try "Coleoptera"

after #26 is resolved, we will be able to better troubleshoot this.
