* Repository of MetadataReport instances that can talk to remote metadata server.

* MetadataReport instances are initiated during the beginning of deployer.start() and used by components that

* If multiple metadata reports and registries need to be declared, it is recommended to group each two metadata report and registry together by giving them the same id:
