Hi all,
After three years of continued work and draft documents, today we are glad to announce the release of the final XISF Version 1.0 Specification document:
pixinsight.com
XISF stands for Extensible Image Serialization Format, and as you probably know, is the native file format of the PixInsight platform for storage, management and interchange of digital images and associated data. XISF is a free, open format, where we welcome the contributions of anyone interested, including users of PixInsight and other applications, as well as individuals and groups from other development teams, institutions and companies involved or interested in image processing software.
For general information on XISF, including the latest news on the format and its development:

For discussion on the XISF specification, its applications and implementations, feel free to join us at PixInsight Forum:
Along with the XISF formal specification document, we have completed also our first reference implementation in the C++ programming language:
The reference XISF implementation is part of the PixInsight Class Library (PCL), available at our official open-source repositories:
With this reference implementation, adding support for monolithic XISF files to existing applications cannot be easier. We'll be glad to help any developer interested in this task.
Thank you for your attention.
