    Thanks for working on this!  It would be great to have more uniform support here.  However, I wonder if the implementation can't be simpler?  Perhaps we could just add a `describe` method to catalog and then a simple `RunnableCommand` that just calls that.  This way even if we add other types of Catalogs, we don't have to add more commands.
    
    I propose we close this issue for now, and have a discussion about the schema for the values returned by `catalog.describe` on the JIRA.  Once we have agreement would be awesome if we can target this for 1.4.
