Subject: Registration of MIME type: application/pdf

Subject: Registration of new MIME content-type/subtype
MIME type name: application
(If the above is not an existing top-level MIME type,
please explain why an existing type cannot be used.)
MIME subtype name: pdf
A Content-Type of "application/pdf" indicates a document in
Portable Document Format. Currently there are two variants of
the PDF language: the original level 1 variant is described
in [PDF] and the more recent level 1.1 variant is described
in an Adobe Systems Application Note that is an addendum to [PDF].
Required parameters: none
Optional parameters: none
Encoding considerations: PDF files may contain binary data (either
in strings or in streams (which are used to represent images
among other things).
Security considerations:
There are two levels of viewer for PDF files: The first level of
viewer is completely self contained and is capable of displaying
or printing the PDF file and maybe capable of changing the file
and writing out a revised file. (Here "file" stands for the MIME
content portion that is in PDF form.) The second level of viewer
is capable of supporting plug-in modules that extend the
functionality of the viewer and may be able to perform any
operation that is legal in the process/thread in which the
viewer is running. Message-sending software should not make use
of arbitrary plug-ins; they are likely to be missing from
some implementations. Message-receiving and -displaying software
should make sure that any nonstandard viewer plug-ins are
secure and don't present any kind of threat.
Published specification:
[PDF](Version 1.0): Portable Document Format Reference Manual,
Adobe Systems, Inc, Addison-Wesley Publishing Co. ISBN
0-201-62628-4, 1993.
Version 1.1: An Adobe Systems, Inc Technical Note
(The published specification must be an Internet RFC or
RFC-to-be if a new top-level type is being defined, and
must be a publicly available specification in any
case.)
