I have attached three documents created as a part of my
analysis.
UIF-Analysis.pdf This is a summary of the TIFF Tags and
their functions that are currently defined in the UIF
specification. This document should provide a useful
reference for any discussion in the meeting.
TIFF2IPP.pdf This is my proposal for the additional
attributes and values required to provide the current
functionality available in TIFF. The actual attribute
specifications are not included in this document, but
they can easily be generated based upon the information
in this document. If this proposal is accepted by the
group, I would be glad to generate the initial attribute
definitions.
DSN-Media-Features.pdf A summary of the DSN/MDN Feature
Extensions. I looked at several other alternatives to see
if there were any other alternatives to TIFF that would
be a reasonable substitute. This document provides the
closest match. Others that I looked at include MIME types
and Cascading Style Sheets (CSS). In addition to the fact
that none of these specifications provide a good match,
any of these would require the support of another protocol
and encoding very different than IPP.
Use of IPP attributes in place of TIFF has two major
issues.
1) A fairly large number of IPP attributes and values
will be required to fully support the TIFF
functionality. I believe that a prudent analysis of
the need for the current set of TIFF requirements will
reduce this number to a more reasonable level.
2) IPP attributes cannot easily support Mixed Raster
Content (MRC). The need for MRC support needs to be
carefully examined.
I was not able to obtain approval to attend the Portland
meeting so I hope someone will volunteer to lead the
discussion on this topic. The IPP method appears to be a
reasonable approach but I strongly feel that PDF has the
potential for the cleanest solution. However, if there are
any concerns or problems with the use of PDF, this would be
the next best choice.
