Thanks for the info @maz and @flamber.
The Data Reference feature is quite good for our data team who know where it is and can make sense of it. The data dictionary would be aimed at providing a more verbose and general description of all of our tables and fields for infrequent users. I want to point them to a single dashboard where they can read everything they need. They might even use it as a sort of menu to choose fields from. The current Data Reference is a bit too buried to rely on them finding it if they don’t spend a lot of time in Metabase.
My ideal solution was almost possible using existing tools. I wanted to put all of the data dictionary entries as rows in a table so that they could be searched and filtered on. E.g.,
||The full name of a person
||A person’s 6 digit ID number
The only thing stopping me from using this is that I cannot wrap lines or resize columns in a Table viz.
