public class Metadata
extends java.lang.Object

A Metadata is a collection of Artifacts with unified metadata (including MRL) that are stored in the same "metadata.json" file.

All of the artifacts located within the metadata share the data defined at the metadata level such as name, description, and website. The key difference between the artifacts within the same metadata are the properties.
