OpenC2 JSON Abstract Data Notation (JADN) Version 2.0 CSD01 – Available for comment
public review ends April 28th
OASIS and the OpenC2 TC are pleased to announce that OpenC2 JSON Abstract Data Notation (JADN) Version 2.0 is now available for public review and comment.
JSON Abstract DataNotation (JADN) is an information modeling language based on Unified Modeling Language (UML) logicalDataTypes, used to both express the meaning of data items at a conceptual level and formally define andvalidate instances of those types. JADN uses information theory to define logical equivalence, which
enables representation of essential content in a wide range of formats and ensures translation among representations without loss.
