    <name>DSpace (Deprecated) REST Webapp :: Local Customizations</name>
    <description>
        This project allows you to overlay your own local REST customizations
        on top of the deprecated REST API provided with DSpace. NOTE: This REST API is DEPRECATED. Please consider
        using the REST API in dspace-server-webapp instead.
