Many of the changes from Drupal 7 to Drupal 8 involve the use of object oriented code. One particular change is to move away from code specific to nodes to writing the code for entities and then overriding or extending it where necessary for nodes. Conceptually, this results in being able to use much of the same code for other entities including custom entities.
For a small number of taxonomy terms, a select box can be used where the choices are explicitly displayed to the user. But for larger numbers of terms using a select box becomes problematic. Using a textfield with autocomplete is an obvious option when there are a large number of terms but it can be discarded because it is not robust to variations in spelling.

In Drupal 6, the Feeds module has three types of plugins. These are the fetcher, parser and the processor plugins. The processor plugins that are supplied with the Feeds module are for data, nodes, taxonomy and users. This article looks at the node processor.
If a feed is imported multiple times to allow the information in the feed to update the Drupal site, thre are three options under the node processor settings. These are

Hook_form_FORM_ID_alter() he crowed triumphantly. I thought it strange to rely on the order of calling these two hooks since there is nothing that guarantees that the order will always be the same. In fact, his claim is only true for Drupal 6. The order
