8 Conformance Testing
Table 2 provides the Conformance Testing Method for OSD-VOI AIM. Conformance Testing of the individual AIMs of the OSD-VOI Composite AIM are given by the individual AIM Specification.
Note that a schema may contain references to other schemas. In this case, validation of data for the primary schema implies that any data that refers to a secondary schema shall also validate.
Table 2 – Conformance Testing Method for OSD-VOI AIM
| Receives | Visual Scene Geometry | Shall validate against Visual Scene Geometry schema. |
| Visual Objects | Shall validate against Visual Objects schema. Visual Data shall conform with Qualifier. |
|
| Body Descriptors | Shall validate against Body Descriptors XML schema. | |
| Produces | Visual Instance ID | Shall validate against Instance ID schema. |
