What is a VAD?

General Structure | Sample VAD | VAD Schema

A VAD file is:

  • A well-formed XML document that:
    • Validated against the MPEG7 CDP XSD schema.
    • Conforms to any constraint developed in the context of the VAD project.

The structure of a typical CDP file is:

<!-- An XML declaration -->
<?xml version="1.0" encoding="iso-8859-1"?>
<!-- An MPEG7 element -->
<Mpeg7 [...] >
<!-- An optional metadata element -->
<DescriptionMetadata>
[...]
</DescriptionMetadata>
<!-- One or more description element -->
<Description xsi:type="ContentEntityType">
[...]
</Description>
</Mpeg7>
