Step 2. List hierarchy model relationships

You can retrieve the top-level code list and the relationships between code lists in a hierarchy model. Then, based on the hierarchy model, you can import hierarchy relationships between code values in the code lists.

To retrieve the relationships in a hierarchy model, use the List hierarchy model relationships REST API.

For more information about the List hierarchy model relationships REST API, see Get hierarchy model relationships (v1).

For example, the following request retrieves the relationships in a hierarchy model:

GET https://use4-mdm.dm-us.informaticacloud.com/rdm-service/external/v1/hierarchies/6e7dd28fc13b417c5c19d1fb/relations HTTP/1.1
Accept: application/json
IDS-SESSION-ID: XXXXXXXXXXXXXXXXXXXXXX

For example, the List hierarchy model relationship REST API returns the following relationships:

HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
Content-Length: 452

{
  "relations":[
    {
      "child":{
        "codeListId":"8bc955e614df2040968e9d85",
        "codeListName":"Parent Codelist",
        "termId":"28a1320fe7f63cd25b58bef4",
        "termName":"Reference Data Set"
      }
    },
    {
      "parent":{
        "codeListId":"8bc955e614df2040968e9d85",
        "codeListName":"Parent Codelist",
        "termId":"28a1320fe7f63cd25b58bef4",
        "termName":"Reference Data Set"
      },
      "child":{
        "codeListId":"81a714a66863f954a9b60045",
        "codeListName":"First Level Codelist",
        "termId":"28a1320fe7f63cd25b58bef4",
        "termName":"Reference Data Set"
      }
    }
  ]
}

The

child.codeListId

attribute contains the top-level node relationship. For example, the first relationship in the example is the top-level node relationship.
