RFC 6283: Extensible Markup Language Evidence Record Syntax (XMLERS), A. Jerman Blazic, S. Saljic, T. Gondrom2011-07-01T23:00:00-00:00In many scenarios, users must be able to demonstrate the (time of) existence, integrity, and validity of data including signed data for long or undetermined periods of time. This document specifies XML syntax and processing rules for creating evidence for long-term non- repudiation of existence and integrity of data. The Extensible Markup Language Evidence Record Syntax XMLERS provides alternative syntax and processing rules to the ASN.1 (Abstract Syntax Notation One) ERS (Evidence Record Syntax) (RFC 4998) syntax by using XML.
