The Basic Visual Scene Description (OSD-BVS) AIM describes the acquired Basic Visual Object as Basic Visual Scene Descriptors. It raises an Alert when what it describes warrants one, without waiting for integration. Spatial Attitude and Basic Environment Descriptors are optional inputs, so that the same AIM serves applications that have something to connect to them and applications that do not.
| Receives | Basic Visual Object | The acquired Basic Visual Object. |
| Spatial Attitude | Spatial Attitude of the application (ego), when it has one. | |
| Basic Environment Descriptors | Descriptors of the environment, when the application has them. | |
| Produces | Basic Visual Scene Descriptors | The description of the Visual scene. |
| Alert | Raised when what is described warrants one. |

8 Conformance Testing
Table 2 provides the Conformance Testing Method for the OSD-BVS AIM.
If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present, and conform with the Qualifier, if present.
| Receives | Basic Visual Object (Basic Visual Object) | Shall validate against the Basic Visual Object schema. |
| Spatial Attitude (Spatial Attitude) | Shall validate against the Spatial Attitude schema. | |
| Basic Environment Descriptors (Basic Environment Descriptors) | Shall validate against the Basic Environment Descriptors schema. | |
| Produces | Basic Visual Scene Descriptors (Basic Visual Scene Descriptors) | Shall validate against the Basic Visual Scene Descriptors schema. |
| Alert (Alert) | Shall validate against the Alert schema. |
