The invitation to comment on this specification ends January 27th
OASIS and the OASIS Open Command and Control (OpenC2) TC are pleased to announce that Specification for JSON Abstract Data Notation Version 1.0 is now available for public review and comment. This is the first public review for this specification.
JSON Abstract Data Notation (JADN) is an information modeling language. It has several purposes including defining data structures, validating data instances, informing user interfaces working with structured data, and facilitating protocol internationalization. JADN specifications consist of two parts: abstract type definitions that are independent of data format, and serialization rules that define how to represent type instances using specific data formats. A JADN schema is itself a structured information object that can be serialized and transferred between applications, documented in multiple formats such as text-based interface definition languages, property tables or diagrams, and translated into concrete schemas used to validate specific data formats.
