        { # Message for response to listing data exchanges in an organization and location.
      "dataExchanges": [ # The list of data exchanges.
        { # A data exchange is a container that lets you share data. Along with the descriptive information about the data exchange, it contains listings that reference shared datasets.
          "description": "A String", # Optional. Description of the data exchange. The description must not contain Unicode non-characters as well as C0 and C1 control codes except tabs (HT), new lines (LF), carriage returns (CR), and page breaks (FF). Default value is an empty string. Max length: 2000 bytes.
          "displayName": "A String", # Required. Human-readable display name of the data exchange. The display name must contain only Unicode letters, numbers (0-9), underscores (_), dashes (-), spaces ( ), ampersands (&) and must not start or end with spaces. Default value is an empty string.

Max Size: 3.0MiB Expected image dimensions are 512x512 pixels, however the API only performs validation on size of the encoded data. Note: For byte fields, the content of the fields are base64-encoded (which increases the size of the data by 33-36%) when using JSON on the wire.
          "listingCount": 42, # Output only. Number of listings contained in the data exchange.
          "name": "A String", # Output only. The resource name of the data exchange. e.g. `projects/myproject/locations/us/dataExchanges/123`.
