8 Conformance Testing
Table 2 provides the Conformance Testing Method for OSD-USD 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-USD AIM
| Receives | Space-Time | Shall validate against Space-Time schema. |
| Ultrasound Objects | Shall validate against Ultrasound Object schema. Media-specific Data shall conform with their Qualifiers. |
|
| Scene Descriptors | Shall validate against Scene Descriptors schema. | |
| Produces | Ultrasound Scene Descriptors | Shall validate against Ultrasound Scene Descriptors schema. |
| Alert | Shall validate against Alert schema. |
