[fitsbits] Start of the FITS MIME type Public Comment Period
ANNOUNCEMENT: Start of the Public Comment Period on the
FITS MIME type proposal This is to announce the official start of the 4-week formal Public Comment Period on the proposal to register 2 new Internet MIME media types for FITS data files: "image/fits" and "application/fits". The latest 17-May-2004 draft of the MIME type proposal is available for comment at http://www.ucolick.org/~sla/fits/mime/. The draft is available there in postscript, PDF, and plain text formats. Listings of the differences with the previous 2 drafts of the document are also available. Please submit your comments here on the sci.astro.fits newsgroup, or on the related FITSBITS moderated mail list. If you previously submitted comments that have not been incorporated in this latest draft, and if you feel that they still need to be addressed, then please submit the comments again. The previous informal discussions about this FITS MIME proposal on the 'fitsmime' mail list at NRAO may be viewed in the archive at http://listmgr.cv.nrao.edu/pipermail/fitsmime/. Other related postings here on the FITSBITS mail list may be viewed in the archive at http://listmgr.cv.nrao.edu/pipermail/fitsbits/. In particular, see the postings in December 2002, June 2003, and March 2004, Approval Procedures ------------------- Under the recently updated "Rules and Procedures" of the IAU FITS Working Group, the first step in the official approval process of any FITS proposal will be a formal Public Comment Period to take place here on the sci.astro.fits newsgroup (and on the moderated FITSBITS mail list that mirrors all on-topic postings). At the end of this public comment period the 3 regional FITS committees (North America, Europe, and Japan) will vote on the proposal. Following that the IAU FITS Working Group will then conduct a final vote to approve or disapprove the proposal. These rules and procedures are more fully described at http://fits.gsfc.nasa.gov/iaufwg/iaufwg_rules.html. It is important to keep in mind that the proposal currently under discussion is simply whether or not to submit the FITS MIME document to the IETF (Internet Engineering Task Force) for consideration as an Internet Standard. The proposal will then go through another whole review process before it can be adopted as an Internet Standard. This process is describe in more detail in RFC 2026 which is available at http://www.ietf.org/rfc/rfc2026.txt.

I believe that specifying two media types, application/fits and image/fits, is confusing and unnecessary. A single type, application/fits, should suffice. The proposal does not provide clear, unambiguous instructions for determining whether a given FITS file should be described as application/fits or image/fits. The apparent intent of the proposal is that the choice of media type should be used to convey information about the file that cannot be determined merely by examining the contents of the file. I think this is a mistake that will lead to confusion and incompatibilities in implementation. I understand that the authors of the proposal do not agree with me, but I think this issue still needs further clarification. Tim Pearson Timothy J.

There are other existing MIME types which do not provide unambiguous instructions for determining what they contain or how to process them. In particular see application/applefile http://www.iana.org/assignments/medi...tion/applefile multipart/appledouble http://www.iana.org/assignments/medi...rt/appledouble These two apple MIME types are described by a single document. In a way they are like a MEF file which may be intended to convey one principal image, or which may contain almost any other form of data. As with FITS, the apple data types were designed to do things far more general than the simple classifications that MIME provides. I take the above as an indication that the IANA namespace need not be conserved so preciously as to inhibit potential users of the MIME types from doing useful work. Indications are that the existing usage of FITS is already so broad that there is no way to provide an absolutely firm dividing line between what is and is not simply an image in the MIME sense. Many FITS files definitely fit the MIME categorization of image, and my impression is that the VO community would be adversely affected if image/fits were not registered. -- Steve Allen UCO/Lick Observatory Santa Cruz, CA 95064 Voice: +1 831 459 3046 http://www.ucolick.org/~sla PGP: 1024/E46978C5 F6 78 D1 10 62 94 8F 2E 49 89 0E FE 26 B4 14 93 |
