XMP, which stands for Extensible Metadata Platform, is an open standards–based labeling technology that allows you to embed data about a file into the file itself. You can choose to include or exclude XMP metadata by clicking the menu icon of the Advanced Settings area (shown in Figure 15-23) and selecting or deselecting Include Source XMP Metadata.

To modify the XMP metadata in your video or audio file, select File Info.This will open the XMP window shown in Figure 15-24. As you can see, the categories of information are extensive, but because XMP is open and therefore allows for the possibility of being extended rather than replaced, it can be made to include more information as more people adopt it without making older metadata obsolete.
