The Open Packaging Format (OPF) is a critical component in the EPUB digital publishing standard, specifically designed for eBooks. OPF files serve as a manifest that organizes and structures the contents of an EPUB file, including metadata, the reading order, and resource files. This standard, introduced by the International Digital Publishing Forum (IDPF) in 2007, aimed to streamline the publication and distribution of eBooks, ensuring compatibility across various devices and reading software. The OPF's primary purpose is to enhance the accessibility and interoperability of digital content within the rapidly evolving landscape of electronic publishing.
The LRF (Sony Portable Reader File) is a proprietary eBook format developed by Sony for its eReaders, such as the Sony Reader. It stores eBooks and textual content in a compressed binary format, including text, images, and pagination data. Introduced as part of the Broad Band eBook (BBeB) family, LRF files are unencrypted, whereas their encrypted counterparts use the LRX extension. The format became obsolete in 2010 when Sony transitioned to the EPUB format. Despite its obsolescence, LRF files can still be opened and converted using various software tools.
