Columns
Each source column, with the name and type we use to store it.
The publisher has not provided a data dictionary.
0 of 9 columns carry a concept; 0 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
