Hello Danielle,

Have you already discovered the [Training feature classifiers tutorial](https://docs.qiime2.org/2021.11/tutorials/feature-classifier/)? That includes a section on importing taxonomy txt files into the `FeatureData[Taxonomy]` format.

There is also [a pipeline](https://forum.qiime2.org/t/processing-filtering-and-evaluating-the-silva-database-and-other-reference-sequence-data-with-rescript/15494) that automates lots of this process, which is also worth a look! ⏩ 🎢

Let me know if you have any other questions!
