/**
 * API to return METS dissemination and Attachments from Fedora.
 * Also renders METS XML for preview. Structure of the URIs totally
 * depend on proper RealURL configuration.
 *
 * Example:
 *
 * 1. METS from Fedora
 *   http://localhost/api/qucosa:1234/mets/
 *
 *   This always returns METS which is supplemented with additional information.
 *   The embedded MODS record is not the original MODS as it is stored in the
 *   repository datastream.
 *
 * 2. Attachment from Fedora
 *   http://localhost/api/qucosa:1234/attachment/ATT-0/
 *
 * 3. METS from Kitodo.Publication (this extension)
 *   http://localhost/api/3/preview/
 *
 * 4. DataCite from Kitodo.Publication (this extension)
