\section{Introduction \& Summary}
This document lays out a structure for representing UEFI CPER records, as described in UEFI Appendix N
\footnote{Version referenced is \href{https://uefi.org/sites/default/files/resources/UEFI_Spec_2_9_2021_03_18.pdf}{UEFI Specification 2021/03/18}.},
 in a human-readable JSON format, intended to be interoperable with standard CPER binary.
\\\\
The C library released with this specification allows for the conversion between UEFI CPER records, an intermediate format, and the JSON structures
defined in this document. There is also a comprehensive JSON schema\footnote{As defined by \href{https://json-schema.org/draft/2020-12/json-schema-core.html}{JSON schema Draft (2020/12)}} included within the same repository, at \texttt{specification/json}.
