How to Get and Set Item Metadata

[Justin T - Hyper Brew]

Has anyone had success with accessing and setting metadata for After Effects folders?

In Premiere Pro using ExtendScript I'd access an item's metadata with .getProjectMetadata(); and add to the metadata with app.project.addPropertyToProjectMetadataSchema(), but the only attributes/methods I can seem to find for AE is the app.project.xmpPacket.

Any thoughts are appreciated.

Thanks,

Justin
