The $metadata variable contains a dictionary of metadata. The keys of the dictionary are the metadata keys of the document, and their values.

The metadata variable is not available for personal books.

For example:

{ft:editorialType=book, FT_Version=Latest, Category=Technical Notes, ft:prettyUrl=Integrate-the-Fluid-Topics-API}

Use case:

The following lines show an example of how to use the $metadata variable in the pdf-template.vm file:

<table>
    <tr>
        <td><strong>Audience</strong></td>
        <td>
            #if($metadata["audience"])
                $metadata["audience"]
            #else
                Not defined
            #end
        </td>
    </tr>
    <tr>
        <td><strong>Version</strong></td>
        <td><strong>$metadata["version"]</strong></td>
    </tr>
</table>

The preceding example provides the following result when the audience metadata is defined:

audience_defined

When the audience metadata is undefined, the result is as follows:

audience_undefined

When a single template is used multiple times, it is necessary to use the #if Velocity directive to apply the metadata variable correctly.
