Keyman Package Metadata files

Used by:

Keyman applications on all platforms except web.

Description:

The files kmp.inf and kmp.json are metadata for a Keyman package file.

Details:

When Keyman Developer compiles a Keyman package source file (.kps), it creates and automatically adds kmp.inf and kmp.json into the Keyman Package file (.kmp).

Keyman mobile products use kmp.json to install the touch keyboards (.js) in the package.

Keyman on all platforms now use kmp.json to install the keyboards (.kmx) in the package.

Older versions of Keyman Desktop for Windows use kmp.inf, a parallel format of the package metadata. Note: the lexical model compiler does not add kmp.inf, and future versions of Keyman Developer will stop supporting kmp.inf.

Package purposes:

A Keyman Package file can be used to distribute keyboards (most common), lexical models, or user interface localizations for Keyman Desktop.
