What is metadata and what metadata we use ? some background
In the Metadata tab, users can add brief description of the purpose, scope and any issues that a model currently has. These information can be helpful to the other users when they determine if they wish to request access from the creators.
Users can add any relevant metadata to the model details in this section, the button 
will prompt the users to a pop up window to add details. Users can edit existing metadata by clicking on the 
and the 
button will copy the metadata id to the clipboard.
When adding new metadata, users can add descriptions and relevant keywords. The 'Number' field automatically assigns a number to each metadata. This works as a unique identifier for the metadata. Currently it is used in the Versions section and it helps with identifying and selecting relevant metadata when creating new versions.
This is good
