Todd’s commentary: This whole conference really opened my eyes to how important taxonomies are in other fields. There was a very humourous debate session during the conference that I didn’t manage to take notes on, but Majorie had an incredible amount of insight on taxonomy standards.

What are the for?

Vocabulary control
