Bug 214716 – app-misc/mime-types-7: add image/jp2 for jpeg2000 and others

• Product: Gentoo Linux
• Status: VERIFIED DUPLICATE

[Description Martin von Gagern 2008-03-25 15:21:45 UTC]

The file /etc/mime.types should contain a line for image/jp2 which is an officially assigned MIME type for JPEG2000. There are two other formats associated with the JPEG2000 compression mechanism and registered with IANA. I suggest addin these three types to mime.types:

image/jp2					jp2 jpg2
image/jpm					jpm jpgm
image/jpx					jpf

Tool examining IANA registry

While looking for missing type definitions in general, I wrote this small application that traverses the IANA registry (using dev-perl/WWW-Mechanize), remembers the types it finds there, and tries to find out the associated file extensions as well. I thought it might be useful to maintainers of the mime-types package, so I attach it here.

There is a line near the end marked with "EDIT HERE" where you can specify what kind of results you want to actually include in the program output. Right now it skips types with no hints as to the file extension, as well as vendor specific types (containing /vnd.). You might wish to modify this selection.

The most notable non-image types currently missing in mime-types-7 seems to be application/fastinfoset and application/relax-ng-compact-syntax. Several others have additional extensions, especially many */prs.* types.

BTW, is there any reason against including all IANA registered types? You don't have to associate any file extensions to rarely used types, but the types themselves should do little harm, except for making the mime.types file a bit larger.
