Packaging
The icondef.xml file and multimedia object files must be packaged in the ZIP format following the below hierarchy (the root directory must exist in the package, with all files and subdirectories within it).
File Format
The package must have the file extension .jisp (Jabber Icon Skin Package), and the MIME type application/vnd.jisp as defined in the official IANA registration. This allows Jabber clients to automatically install Icon Skins through web browsers.
When the client installs the package, it should probably be kept in the archived format, instead of unzipped. This not only saves disk space, but also makes the packages easier to manage and exchange. However, this is optional.
Hierarchy
The icondef.xml file and multimedia object files must all be located in or below the same root directory, which is named after the style and version (example: ./happy_days-1.2 or ./gold_angelic-1.0.0 ).
