+# OVN Request Optional Extension to ASTM F3548-21 Requirements
+This optional extension not part of the original F3548 standard API allows a USS to request a specific OVN when creating
+or updating an operational intent.
+
+## DSS requirements
+### <tt>ImplementAPI</tt>
+If a DSS has support for the optional extension, it must implement the endpoints `createOperationalIntentReference` and
+`updateOperationalIntentReference` with the support for the optional field `requested_ovn_suffix` as defined in the API,
+accept requests in the data format prescribed in the API, and respond in the data format prescribed in the API.
+If there is a problem using the API such as a connection error, invalid response code, or invalid data, the DSS will
+have failed to meet this requirement.

+# OVN Request Optional Extension to ASTM F3548-21 test scenario
+
+## Description
+This test validates that a DSS correctly implements the [OVN Request Optional Extension to ASTM F3548-21](../../../requirements/interuss/f3548/ovn_request.md).
+
+## Resources
+
+### dss
+[`DSSInstanceResource`](../../../resources/astm/f3548/v21/dss.py) to be tested in this scenario.
+
+### 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](../../astm/utm/dss/clean_workspace.md)
+This step ensures that no entities with the known test IDs exists in the DSS.
+
+## Request for OIR OVN with valid suffix test case
+This case validates the nominal behavior of the OVN request.
+
+### Create OIR with OVN suffix request test step
+
+#### [Create OIR with OVN suffix request](../../astm/utm/dss/fragments/oir/crud/create_query.md)
+Check that the OIR creation query succeeds.
+
+#### [DSS has set the expected OVN using the requested OVN suffix](./expected_ovn_set_fragment.md)
+Check that the DSS has set the expected OVN correctly.
+
+### Activate OIR with OVN suffix request test step
+
+#### [Update OIR with OVN suffix request](../../astm/utm/dss/fragments/oir/crud/update_query.md)
+Check that the OIR update query succeeds.
+
+#### [DSS has set the expected OVN using the requested OVN suffix](./expected_ovn_set_fragment.md)
+Check that the DSS has set the expected OVN correctly.
+
+## Request for OIR OVN with invalid suffix test case
+This case validates the off-nominal behaviors of the OVN request.
+
+### Attempt to create OIR with OVN suffix request not being a UUID test step
+#### [Attempt to create OIR with OVN suffix request not being a UUID rejected check](./invalid_ovn_suffix_fragment.md)
+Check that the DSS rejects OVN suffix that are not UUIDs.
+If the DSS accepts the OVN suffix, or fails with an unexpected error, this check will fail.
+
+### Attempt to create OIR with OVN suffix request empty test step
+#### [Attempt to create OIR with OVN suffix request empty rejected check](./invalid_ovn_suffix_fragment.md)
+Check that the DSS rejects OVN suffix that are empty.
+If the DSS accepts the OVN suffix, or fails with an unexpected error, this check will fail.
+
+### Attempt to create OIR with OVN suffix request being a UUID but not v7 test step
+#### [Attempt to create OIR with OVN suffix request being a UUID but not v7 rejected check](./invalid_ovn_suffix_fragment.md)
+Check that the DSS rejects OVN suffix that are UUIDs but not v7.
+If the DSS accepts the OVN suffix, or fails with an unexpected error, this check will fail.
+
+### Attempt to create OIR with OVN suffix request being an outdated UUIDv7 test step
+#### [Attempt to create OIR with OVN suffix request being an outdated UUIDv7 rejected check](./invalid_ovn_suffix_fragment.md)
+Check that the DSS rejects OVN suffix that are outdated UUIDv7.
+If the DSS accepts the OVN suffix, or fails with an unexpected error, this check will fail.
