8 Conformance Testing
Table 2 provides the Conformance Testing Method for the OSD-SDX AIM as a Basic 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.
Table 2 – Conformance Testing Method for OSD-SDX AIM
| Receives | Audio-Visual Scene Descriptors | Shall validate against AV Scene Descriptors schema |
| Produces | Speech Scene Geometry | Shall validate against Speech Scene Geometry schema |
| Audio Scene Geometry | Shall validate against Audio Scene Geometry schema | |
| Visual Scene Geometry | Shall validate against Visual Scene Geometry schema | |
| Speech Objects | Shall validate against Speech Objects schema Speech Data shall conform with Qualifier |
|
| Audio Objects | Shall validate against Audio Objects schema Audio Data shall conform with Qualifier |
|
| Visual Objects | Shall validate against Visual Objects schema Visual Data shall conform with Qualifier |
