DMN17 — Shared Data Model and Notation (SDMN)

Situational Data is the set of Data Items and their structures that are needed for the performance and understanding of a Knowledge Package Model.
The details of the Data Items will usually be a subset of the “official” complexity of those items in the environment of the Knowledge Package Model.
For example, the official definition of the Data Item for Blood Pressure (in healthcare) includes more than 50 properties. A Data Item in a Situational Data Model may need only 2 of those properties for execution of the Processes, Cases, and or Decision Services.
Semantic References can be added to link the Data Item to the “official” details.
Uses of the Data Items in BPM+ models that determine the scope of Situational Data include:
Data required for DMN Decisions
Data required for BPMN Gateways transitions
Data required to be passed to/from services invoked by BPMN and CMMN
Data required to trigger Sentries in CMMN
Etc.
