# Administer Structured Classifiers

After you have set up classification, you can list and delete structured categories and structured classifiers.

## List Categories and Classifiers

The StructuredCategoryList and StructuredClassifierList actions allow you to list the structured categories and structured classifiers that you have created.

For example:

    action=StructuredCategoryList

This action returns the names of all your structured categories.

    action=StructuredClassifierList

This action returns the names of all your structured classifiers, and the structured categories that it contains.

## Delete a Structured Category

You can delete a structured category by using the StructuredCategoryDelete action. You can only delete a structured category if it is not associated with a structured classifier.

For example:

    action=StructuredClassifierDelete&Name=Film

This action deletes the `Film` structured category.

## Delete a Classifier

You can delete a structured classifier that you no longer need by using the StructuredClassifierDelete action. This action deletes the classifier and all associated classes.

For example:

    action=StructuredClassifierDelete&Name=TypeClassifier

This action deletes the `TypeClassifier` structured classifier.

You can optionally use the DeleteStructuredCategories parameter to delete all the structured categories associated with the structured classifier.
