OpenRaster Image File (.ora)
The ORA file extension stands for OpenRaster Image File, a format designed for the exchange of layered raster graphics between different software applications. Proposed in 2006 by developers from KDE and Krita, OpenRaster aims to provide an open alternative to proprietary formats like Adobe's PSD. The format encapsulates image layers, blending modes, and metadata within a ZIP archive containing XML and PNG files. Its primary use is to facilitate interoperability among various graphic editors, ensuring that complex image data can be shared and edited across different platforms.
