In the file manager Thunar, Hydrogen is presented as a handler for SVG files.
Is this caused by the line

MimeType=text/xml;

in /usr/share/applications/hydrogen.desktop ?

Perhaps SVG is a subset of XML? So, in claiming to handle XML, Hydrogen is
presented as a handler for SVG files indirectly?

Anyway, Hydrogen does nothing useful when opening an SVG file, of course.

Therefore I ask, is it sensible that Hydrogen should register itself as
a handler for general XML files? Wouldn't it be better to define a new MIME
type, e.g. audio/x-hydrogen-pattern and audio/x-hydrogen-song, determined
by the appropriate suffixes for the two different Hydrogen file types
*.h2song and *.h2pattern? Or both file suffixes could be used for a single
MIME type audio/x-hydrogen.

I'm no expert on MIME types, though.

Hydrogen's song and drumkit files are indeed XML files.
But no, Hydrogen does not handle SVG files (which are also
XML files).

I think this is a bug in Thunar.  The mime type for SVG is
"image/svg+xml"[1]

Thanks!

I've posted about it over at the XFCE forum:

http://forum.xfce.org/viewtopic.php?pid=21849

and will await their response. I included a link here for them to check out. I'll
come back here and closee this report later after I have some more info.

While I agree that it might be a bug in Thunar to not use the Mime type
image/svg+xml for *.svg files, it is still a problem that Hydrogen will be
registered as a handler for *.xml files, right?

For a general *.xml file, I'd expect that the mest sensible would be that the
file manager only proposes to open it in text editors, specialized XML viewers
and editors. And there is nothing a file manager can do to avoid proposing to
open such files in Hydrogen as long as the line MimeType=text/xml is in
hydrogen.desktop?

I had a look at this, and with xfce today in testing, hydrogen is not proposed
as a application to use to open its own files when marking it in the file
manager.  I believe this is a bug and related to the issue in this bug request.

When running 'file --mime-type' on a .h2song file, the mime type returned is
application/xml.  This mime type is not listed in the hydrogen.desktop file.

But instead of just replacning text/xml with application/xml in the desktop
file, I propose to add a new file under /usr/share/mime/ specifying a mime
type for files ending in .h2song, and list this new mime type in the desktop
file.

The /usr/share/mime/packages/rosegarden.xml file look like this:

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="audio/x-rosegarden">
    <sub-class-of type="application/x-gzip"/>
    <comment>Rosegarden project file</comment>
    <glob pattern="*.rg"/>
  </mime-type>
</mime-info>

I am not sure if there is a well known MIME type already for hydrogen h2song,
but if it is not, perhaps audio/x-hydrogen-song would work?  Then I guess
something like this should go into /usr/share/mime/packages/hydrogen.xml:

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="audio/x-hydrogen-song">
    <sub-class-of type="application/xml"/>
    <comment>Hydrogen Drum Machine project file</comment>
    <glob pattern="*.h2song"/>
  </mime-type>
</mime-info>

And the audio/x-hydrogen-song value be added to the hydrogen.desktop file.
