+Overview
+========
+
+Define mime types for common I2P file formats.
+Include the definitions in Debian packages.
+Provide a handler for the .su3 type, and possibly others.
+
+
+Motivation
+==========
+
+To make reseeding and plugin installation easier when downloading with a browser,
+we need a mime type and handler for .su3 files.
+
+While we are at it, after learning how to write the mime definition file,
+following the freedesktop.org standard, we can add definitions for other common
+I2P file types.
+While less useful for files that aren't usually downloaded, such as the
+addressbook blockfile database (hostsdb.blockfile), these definitions will
+allow files to be better identified and iconified when using a graphical
+directory viewer such as "nautilus" on Ubuntu.
+
+By standardizing the mime types, each router implementation may write handlers
+as appropriate, and the mime definition file may be shared by all implementations.
+
+
+
+Design
+======
+
+Write an XML source file following the freedesktop.org standard and include it
+in Debian packages. The file is "debian/(package).sharedmimeinfo".
+
+All I2P mime types will start with "application/x-i2p-", except for the jrobin rrd.
+
+Handlers for these mime types are application-specific and will not
+be specified here.
+
+We will also include the definitions with Jetty, and include them with
+the reseed software or instructions.

+Notes
+=====
+
+Not all file formats listed above are used by non-Java router implementations;
+some may not even be well-specified. However, documenting them here
+may enable cross-implementation consistency in the future.
+
+Some file suffixes such as ".config", ".dat" and ".info" may overlap with other
+mime types. These may be disambiguated with additional data such as
+full file name, a file name pattern, or magic numbers.
+See the draft i2p.sharedmimeinfo file in the zzz.i2p thread for examples.
+
+The important ones are the .su3 types, and those type have both
+a unique suffix and robust magic number definitions.
