+# ASTM SCD DSS: Operational Intent Reference Simple test scenario
+
+## Overview
+
+Verifies the behavior of a DSS for simple interactions pertaining to operational intent references.
+
+## Resources
+
+### dss
+
+[`DSSInstanceResource`](../../../../resources/astm/f3548/v21/dss.py) the DSS instance through which entities are created, modified and deleted.
+
+### id_generator
+
+[`IDGeneratorResource`](../../../../resources/interuss/id_generator.py) providing the base entity ID for this scenario.
+
+### client_identity
+
+[`ClientIdentityResource`](../../../../resources/communications/client_identity.py) the client identity that will be used to create and update operational intent references.
+
+### planning_area
+
+[`PlanningAreaResource`](../../../../resources/astm/f3548/v21/planning_area.py) describes the 3D volume in which operational intent references will be created.
+
+## Setup test case
+
+### [Ensure clean workspace test step](./clean_workspace.md)
+
+This step ensures that no entities with the known test IDs exists in the DSS.
+
+### [Create an operational intent reference test step](./fragments/oir/crud/create_query.md)
+
+Create an operational intent reference to be used in this scenario.
+
+## Deletion with incorrect OVN is forbidden test case
+
+This test case verifies that an existing OIR cannot be deleted with a missing or incorrect OVN.
+
+### Attempt deletion with incorrect OVN test step
+
+#### 🛑 Request to delete OIR with empty OVN fails check
+
+If the DSS under test allows the qualifier to delete an existing OIR with a request that provided an empty OVN,
+it is in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**
+
+#### 🛑 Request to delete OIR with incorrect OVN fails check
+
+If the DSS under test allows the qualifier to delete an existing OIR with a request that provided an incorrect OVN,
+it is in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**
