Profile contract

dmn.drd@1

DMN 1.4 DRD notation: decision, business knowledge model (clipped corner), input data (rounded), knowledge source (document), decision service (band form); information/knowledge/authority requirement connectors; decision nodes bind decision-table views via x_subdiagram; boxed-expression presentation via x_boxed. NO expression language: FEEL is a host-application (backend) capability, not notation.

Profile verification

Decision, BKM, input, knowledge source and service nodes have distinct endpoint contracts for information/knowledge/authority requirements.
Decision drill-down references resolve to decision views; boxed-expression data validates its presentation shape.
Expressions are displayed as data; neither FEEL nor host expression evaluation is provided.

Profile defaults

Explicit file settings override eligible CSS, then these profile defaults and the common standard apply. Unspecified semantic facts remain unspecified.

Design operations

Create DRD role and requirement connector; bind decision table view; edit boxed-expression presentation.
