when an indd document is saved to the repo, we need to read the 64bit preview that is included in the xmp of the file and create a thumbnail of the file.
see https://github.com/nuxeo-sandbox/nuxeo-indd-rendition/blob/master/nuxeo-indd-rendition-core/src/main/java/org/nuxeo/labs/indd/rendition/InddPreviewHelpe for work that Mika V has done for a demo.
