# Creating fixed Document Definitions

> Build fixed Document Definitions in ABBYY FlexiCapture to capture data from forms whose field layout never changes, such as questionnaires and surveys.

**Forms** are documents containing a set of marked information fields whose formatting, number, and layout do not change from copy to copy. Examples of forms include questionnaires, surveys, and application forms. To identify a form in a document flow and to extract data from it, you need to create a fixed Document Definition that will tell the program where to look for the data fields. For details, see [What types of documents can be processed with ABBYY FlexiCapture](/flexi-capture/overview/document-types).
