How is a prefix identified as such with this technique?
biber uses the btparse library (http://search.cpan.org/~ambs/Text-BibTeX-0.70/btparse/doc/bt_split_names.pod) and prefixes ("von-Parts") are more or less identifyed by lowercase letters (as in bibtex, see also tamethebeast.pdf). I actually run once into a problem with a lowercase name which biber didn't like: https://github.com/plk/biber/issues/43 There are some tricks, like \uppercase{d}, commands, braces, which one can use to fine-tune the name parsing.
Is there a hardcoded list somewhere or is it "name begins with a 'word' in lowercase". IMHO it would be desirable that the prefix itself could be specified in a field.
Well the main problem is that authors are name *lists*, and that there can be more then one name list in an entry. But biblatex is extensible. You can, if you want, define a new field say "authorprefixes={de,von,none,Bbla}" and then write suitable macros that uses this prefixes instead of the one parsed from the name. But I doubt that it is really needed. One shouldn't overcomplicate a system only to catch every special case. -- Ulrike Fischer http://www.troubleshooting-tex.de/
