DDEX compliant metadata specification, Trouble with Google/Android music sign up Options

[CoyoteSmith]

Hello, I'm not having the best of luck at the DDEX website or google finding out what I need to deliver to Google/Android music label signup.

Here is what is requested: "At this time, we require audio deliveries in lossless (FLAC) format, and metadata via a DDEX compliant metadata specification. If that last sentence made any sense to you, then we can move forward. If you don’t have the ability to deliver XML, or use a delivery agency (such as CI or FUGA) to deliver your audio and metadata, we are working on other methods of delivery, and you should check back in a few months to see what alternatives we have made available."

The FLAC part is easy, but I'm not exactly sure what to do as far as the DDEX metadata/xml goes. Any help is appreciated.
