Configure the layers for your deployment
You configure the layers for your multi-level libraries by editing the library-layers.xml configuration file.
In the initial configuration, a single layer is available ("
			library default layer" with the id "1") , as shown
				below:<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE library PUBLIC "-//ixiasoft.com//cms//config//libraryLayers" "librarylayers.dtd">
<!-- ============================================================================================= --> 
<!-- --> 
<!-- FILE: librarylayers.xml --> 
<!-- --> 
<!-- DESCRIPTION: This file defines the available library layers within the docbase. --> 
<!-- Note that layer ID 0 is the Product layer and cannot be modified. Library layer IDs start at 1.-->

<library>
    <layer id="1" name="library" description="library default layer" isDefault="yes"/>
</library>To configure layers, you create one 
			<layer> element per layer. A layer has the following attributes:
					| Attribute | Description | 
|---|---|
| id | Level of the library layer. Library layers
									start at 1, the highest level. You can add as many layers as
									necessary. A library or product can reference content from a
									library that is at the same level (sibling library) or lower
									(child library). The level must be unique within the library-layers.xml configuration file. | 
| name | Name of the library layer. This name is used in the DRM dialogs to identify the layer. Make sure to enter a descriptive name. | 
| description | Description of the library layer. | 
| isDefault | Specifies whether this layer is the default
									layer. Only one layer can be set as the default ( isDefault="yes"). The default
									layer is used for backward compatibility. When an existing
									library version is released, if it does not have a layer level
									associated to it, it will be assigned this default layer. | 
You can add other layers, as appropriate for your deployment. Remember that creating multiple layers will increase the complexity of the IXIASOFT Dynamic Release Management.
| Note: Please contact your IXIASOFT
								DITA specialist before implementing multi-level libraries in your
								deployment, as they increase the complexity of the IXIASOFT CCMS. Multi-level libraries must
								be planned carefully. | 
Note: You should make these configuration changes in
            the Test environment and test them before copying them to the Production environment. In
            a dedicated SaaS deployment, after testing the changes, ask IXIASOFT Customer Support to
            copy the changes to the Production environment.
