# Managing Attributes

A high proportion of the top 30 transformers are support transformers for managing attributes. These create new attributes, rename them, set values, and delete them.

A key use for these transformers is to rename attributes for schema mapping.

## Attribute Managing Transformers

<table><thead><tr><th width="252">Task</th><th>Transformers</th></tr></thead><tbody><tr><td>Create Attributes</td><td>AttributeCreator, AttributeManager</td></tr><tr><td>Set Attribute Values</td><td>AttributeCreator, AttributeManager</td></tr><tr><td>Remove Attributes</td><td>AttributeKeeper, AttributeManager, AttributeRemover, BulkAttributeRemover</td></tr><tr><td>Rename Attributes</td><td>AttributeManager, AttributeRenamer, BulkAttributeRenamer</td></tr><tr><td>Copy Attributes</td><td>AttributeCopier, AttributeCreator, AttributeManager</td></tr><tr><td>Sort Attributes</td><td>AttributeManager</td></tr><tr><td>Change Attribute Case</td><td>BulkAttributeRenamer</td></tr><tr><td>Add Prefixes/Suffixes</td><td>BulkAttributeRenamer</td></tr></tbody></table>

Many of these transformers can carry out similar operations, and you can see that the AttributeManager does so many tasks you can use it almost exclusively.

{% hint style="warning" %}
**WARNING**

*Don't misunderstand the BulkAttributeRenamer. It changes the case, or adds suffixes/prefixes, to the attribute name, not the attribute value.*
{% endhint %}
