Specifies the storage and support requirements for WARC (Web ARChive) file format.
Scope
This document 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.
