I'm moving a large series of vocabulary lists to a new D7 install. I used features to copy over taxonomy groups. However, I only copied over the taxonomy not the vocabulary lists. Is there an extension to features to handle this?
I have never used it quite for this purpose, but the Feeds module will import from CSV files and can create taxonomy terms. The Drupal 7 version still says it is alpha status, but I have been using it for a while now without any real problems with CSV files.
Just make sure your CSV is UTF-8 clean, otherwise you may get some obscure SQL errors if your data has characters with diacriticals, etc.
It looks like Taxonomy CSV import/export did the trick. Here is a quote about it (from the module's project page):
... allows you to import or export taxonomy from or to a CSV (comma-separated values) file or with a copy-and-paste text.
It helps you to quick import a non-standardized vocabulary, for example an old thesaurus, a hierarchical taxonomy or a simple list of children, synonyms, descriptions, weights or related terms to terms. It can be used as a module or as an API with a plug-in mechanism. It can manage internationalized vocabularies with i18n_taxonomy, a submodule of i18n module [Drupal 7 only].
