Metadata Set
A Metadata Set is a system component that provides the interface for customizing the kinds of metadata fields that can be visible and/or associated with an asset. Since metadata fields can be broken into two categories, wired and dynamic, metadata sets allow administrators to choose which wired fields can be made visible to end users and which ones will be turned off. Likewise, the interface allows for dynamic fields to be created that help to further describe an asset beyond the scope of what regular wired fields allow.
Metadata sets also allow for administrators to customize the wired and dynamic metadata fields so that they appear "inline" in the editing interface for an asset instead of appearing in the metadata pane, making the fields more accessible to end users. Additionally, fields can be set to 'required' so that end users must enter acceptable values for metadata before saving the asset.
