# CategoryImportFromDocs

Allows you to import a category hierarchy from path information contained in a particular field in a specified set of documents. The category hierarchy that it creates is empty (untrained), with category names that match the node names in the imported hierarchy data.

You can specify document IDs or references by using DocID or DocRef, or you can define a query to use to identify documents by setting DREQuery. If you do not set any of these parameters, IDOL Server uses all documents.

NOTE: This is an administrative action that can be sent only by users that belong to an authorization role that allows the `Admin` standard role, or which enables the action explicitly. See Authorization Roles Configuration Parameters.
