Yes because these information are stored as metadata (blob) on the document itself. So you should be able to get it back with one of these operations:

http://explorer.nuxeo.org/nuxeo/site/distribution/Nuxeo%20Platform-5.7.3/viewOperation/Blob.Get

You just need to find the right xpath, but an xml export of the document will help figure that out.
