# CDM FAQs

### Where are basionym authorteams?

Year of publication and/or basionym authorteams of a scientific name might be known although the nomenclatural reference or the basionym itself is not known. A “dummy” reference and/or a “dummy” basionym will be created that keeps this data to enforce consistency. See #125

### How can plain lists of literature references be attached to a taxon?

The recommended way is to create an empty Cdm:decription:Description for each literature resource and use the source property to hold the reference.

### Taxon relations vs Name relations

The [[CdmLibrary]] logic does not cross the border between names and taxa. So if you create a new basionym relationship between two names NO homotypic synonym relationship is created automatically. On the contrary if a basionym relationship exists between two names, but no synonym relationship between 2 taxon concepts  with the respective names, the 2 taxa are not considered synonyms!
