Successor to the ARC (Internet Archive) format. Standardized as ISO 28500:2009, Information and documentation -- WARC file format. Developed under the auspices of the International Internet Preservation Consortium. WARC was developed as an extension to ARC in part to provide better capabilities for managing Web archives for the long term, allowing for capture of more metadata about the circumstances of archiving.
WARC files are often compressed using GZIP, resulting in a .warc.gz extension.
