Congratulations to all involved on getting to this stage! There's still the open issue of the MIME type, which was discussed a while back and then dropped. As I read IETF RFC 3302 (http://www.ietf.org/rfc/rfc3302.txt), "image/tiff" is defined in terms of TIFF 6.0 conformity, so it would be incorrect to refer to a BigTIFF document as "image/tiff". IANA has also registered a MIME type "image/tiff-fx" for TIFF-FX, defined by RFC 3950, so it would be consistent to shoot for "image/tiff-big". IANA requires "publication by a formal standards body," though, so it would be more realistic to stake out "image/x-tiff-big". -- Gary McGath Digital Library Software Engineer Harvard University Libraries, Office for Information Systems
