Information about LRF and MOBI file formats

Full name Sony Portable Reader File MOBI - Mobipocket
File extension .lrf .mobi, .prc
MIME type application/x-sony-bbeb application/x-mobipocket-ebook
Developed by Sony Mobipocket SA
Type of format eBook File Ebook file format
Description The LRF file type is a proprietary file type created by Sony with Sony-branded eBook readers. LRF, along with LRS and LRX, made up the now-defunct BroadBand eBook or BBeB. The file type was discontinued in 2010, with the Sony eBook store selling in the ePUB format. The MOBI file extension was created in 2000 by Mobipocket. This company produced Mobipocket Reader applications for computers and smartphones. In 2005, Amazon bought Mobipocket. As a result, MOBI files are identical to Amazon's AZW format for Kindle devices.
Technical details LRF files are compressed, unencrypted files that may contain text and images featuring Sony's DRM protection. In addition, an LRF file may contain one or many LRS files which contain XML structuring. The Mobipocket ebook format is based on the Open eBook standard using XHTML and can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases. The Amazon Kindle's AZW format is just the Mobipocket format with a slightly different serial number scheme, and .prc publications can be read directly on the Kindle. The Kindle AZW format also lacks some Mobipocket features such as JavaScript.
