EMERALD adopted OSCAL as a lingua franca across stakeholders to reduce manual effort, improve interoperability, and enable consistent automation in EUCS aligned processes.

EMERALD has developed a proof-of-concept, mapping several standards (EUCS, BSI-C5, AIC4) to OSCAL, and is able to export/import the schema to/from OSCAL.

A generic OSCAL Json template was developed to describe the elements of a standard, using the Catalog Model (Control Layer) and OSCAL constructs such as groups, controls, parts, properties, and prose.
