Data dictionaries in AWS Data Exchange
A data dictionary is a visual representation of the contents of your data set in AWS Data Exchange.
Subscribers can view and download a data dictionary before they subscribe to your product to evaluate if your product meets their needs.
You can add one data dictionary to each data set, with a maximum size of 1 MB. The accepted file type for a data dictionary is .csv.
When you create a data dictionary, you include details about what columns are included in the data set and their meaning. Your data dictionary must conform to the AWS Data Exchange data dictionary template. You can download the blank data dictionary template from the AWS Data Exchange console. AWS Data Exchange also provides an example data dictionary for you to view as an example.
Note
A data dictionary is attached to a product and associated with a data set. If you want to have more than one data dictionary for potential subscribers to evaluate, you can create two or more versions of the same product with the same data sets. Then, add a different data dictionary to each product.
For more information about how to add a data dictionary to a product, see Publishing a new product in AWS Data Exchange.
