Adding Attributes to the Content Header
To add any information to a Windows Media file , you can add attributes (name-value pairs) to the content header . For example, attributes can be added to identify the source of the Windows Media file, the content owner, the version number of the Windows Media file, and so on. This feature is very useful because it allows the content owner , the content packager , the content distributor , and the license issuer to securely communicate and track information about the file. For example, if a license issuer works with multiple content owners, an attribute could be used to specify who owns the content, and the license issuer could use this information to determine which license key seed and packaging public key to use.
It is recommended that you add the following attributes to each content header.
| Attribute | Description |
| Copyright | Copyright |

| Author | Author or artist name |
| ArtistURL | Artist Web site URL |
| Title | Title |
| LicenseDistributor | License distributor or issuer |
