We're using ArtifactMetadata to abstract what type of artifact it is (whether it is a maven artifact or simply a file in the repository).. Also, if you'll be returning a list of Artifact objects from the SourceArtifact class then from those Artifact objects, you'll be querying for the artifact metadata again in the repository merge, won't it be redundant since in the first place you already have ArtifactMetadata objects in the SourceArtifact class but you returned a list of Artifact objects instead?
