IPTC metadata edit and export

[Rocketdrive 120]

After exporting illustrations from Photo as JPG files, I switch over to bridge and fill in metadata such as description, keywords and copyright. I thought, at some point it would be cool to add IPTC data in Photo directly, and have that attached to all files that support it, like JPG.

Google is starting to show, on image search results, the following metadata: Creator, Credit Line and Copyright Notice.

It would be really good to have at least the possibility of changing/add the above mentioned metadata.
