Scope

ISO 28500:2017 specifies the WARC file format:
- to store both the payload content and control information from mainstream Internet application layer protocols, such as the HTTP, DNS, and FTP;
- to store arbitrary metadata linked to other stored data (e.g. subject classifier, discovered language, encoding);
- to support data compression and maintain data record integrity;
- to store all control information from the harvesting protocol (e.g. request headers), not just response information;
- to store the results of data transformations linked to other stored data;
- to store a duplicate detection event linked to other stored data (to reduce storage in the presence of identical or substantially similar resources);
- to be extended without disruption to existing functionality;
- to support handling of overly long records by truncation or segmentation, where desired.
