There isn't metadata for this, as it is not part of Apple's relationship.

They are a seller of software, and the creator of the software is responsible for making sure the software can be compatible with the licensing and copyright terms of both Apple and any dependencies.

A semantic link to grab the source code for an app would be neat, but a pretty niche feature. That Apple can't verify that it is the same code (or that the separately hosted build process doesn't have malicious logic within it) probably quickly pushed them over the edge in terms of not supporting such a feature.
