+ <p>Five years ago,
+<a href="http://people.skolelinux.org/pere/blog/What_is_the_most_supported_MIME_type_in_Debian_.html">I
+measured what the most supported MIME type in Debian was</a>, by
+analysing the desktop files in all packages in the archive. Since
+then, the DEP-11 AppStream system has been put into production, making
+the task a lot easier. This made me want to repeat the measurement,
+to see how much things changed. Here are the new numbers, for
+unstable only this time:
+
+<p><strong>Debian Unstable:</strong></p>
+
+<pre>
+ count MIME type
+ ----- -----------------------
+ 56 image/jpeg
+ 55 image/png
+ 49 image/tiff
+ 48 image/gif
+ 39 image/bmp
+ 38 text/plain
+ 37 audio/mpeg
+ 34 application/ogg
+ 33 audio/x-flac
+ 32 audio/x-mp3
+ 30 audio/x-wav
+ 30 audio/x-vorbis+ogg
+ 29 image/x-portable-pixmap
+ 27 inode/directory
+ 27 image/x-portable-bitmap
+ 27 audio/x-mpeg
+ 26 application/x-ogg
+ 25 audio/x-mpegurl
+ 25 audio/ogg
+ 24 text/html
+</pre>
+
+<p>The list was created like this using a sid chroot: "cat
+/var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz| zcat | awk '/^
+- \S+\/\S+$/ {print $2 }' | sort | uniq -c | sort -nr | head -20"</p>
+
+<p>It is interesting to see how image formats have passed text/plain
+as the most announced supported MIME type. These days, thanks to the
+AppStream system, if you run into a file format you do not know, and
+want to figure out which packages support the format, you can find the
+MIME type of the file using "file --mime <filename>", and then
+look up all packages announcing support for this format in their
+AppStream metadata (XML or .desktop file) using "appstreamcli
+what-provides mimetype <mime-type>. For example if you, like
+me, want to know which packages support inode/directory, you can get a
+list like this:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype inode/directory | grep Package: | sort
+Package: anjuta
+Package: audacious
+Package: baobab
+Package: cervisia
+Package: chirp
+Package: dolphin
+Package: doublecmd-common
+Package: easytag
+Package: enlightenment
+Package: ephoto
+Package: filelight
+Package: gwenview
+Package: k4dirstat
+Package: kaffeine
+Package: kdesvn
+Package: kid3
+Package: kid3-qt
+Package: nautilus
+Package: nemo
+Package: pcmanfm
+Package: pcmanfm-qt
+Package: qweborf
+Package: ranger
+Package: sirikali
+Package: spacefm
+Package: spacefm
+Package: vifm
+%
+</pre></blockquote></p>
+
+<p>Using the same method, I can quickly discover that the Sketchup file
+format is not yet supported by any package in Debian:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype application/vnd.sketchup.skp
+Could not find component providing 'mimetype::application/vnd.sketchup.skp'.
+%
+</pre></blockquote></p>
+
+<p>Yesterday I used it to figure out which packages support the STL 3D
+format:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype application/sla|grep Package
+Package: cura
+Package: meshlab
+Package: printrun
+%
+</pre></blockquote></p>
+
+<p>PS: A new version of Cura was uploaded to Debian yesterday.</p>
