The .rb extension is used for many formats which include definition files based on the Fuzzy rule, eBook files of the Rocket Edition, class files of Ruby on Rails, project files of REALbasic and the profile configuration files of Rosebud. Other versions of Ruby which are also called gems include Mongrel, Capistrano and Ruby on Rails.
The LRF format is a proprietary format developed by Sony in collaboration with Canon, as a document and text encoding standard for the Broad Band eBook file format. The format specifically targeted Sony portable eBook readers and was capable of encoding both text, pagination, and images. Being unencrypted, LRF encoded files do not enforce DRM. This is in contrast to the LRX format which is also part of the BBeB eBook file format which does support encryption for DRM files. The Sony eBook store announced in July 2010 a discontinuation of support for the LRF format in favor of the public and open EPUB format.

The LRF format is an XML derivative. It represents the compiled and compressed binary format of the BBeB file. The structure of an .lrf file included a header, an object stream, and an object index. Though the LRF format is a proprietary asset, many freely available programs are able to convert and or open LRF files for viewing.
