This datasource identifies an image's source repository according to the [pre-defined annotation keys of the OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/main/annotations.md).
This datasource looks for the metadata of the **latest stable** image found on the Docker registry and uses the value of the label `org.opencontainers.image.source` and `org.label-schema.vcs-url` as the `sourceUrl`.
