----------------------------

             Summary: Name relationship link between two different types in Apache Atlas
                 Key: ATLAS-4410
                 URL: https://issues.apache.org/jira/browse/ATLAS-4410
             Project: Atlas
          Issue Type: Test
          Components:  atlas-core
    Affects Versions: 2.0.0
            Reporter: Saqib
             Fix For: 2.0.0


I am trying to name relationship link (by using attributeDefs) between two different types. The relationship is now registered in Atlas and definition fetch results as below:

 

{{{
"category": "RELATIONSHIP",
"guid": "9b1059c3-8707-46db-ae3c-e8d1b4ef6333",
"createdBy": "admin",
"updatedBy": "admin",
"createTime": 1625233869809,

"version": 6,
"name": "field_assignment",
"description": "someDescription.",
"typeVersion": "1.0",
"attributeDefs": [
    \{
        "name": "LinkInformation",
        "typeName": "string",
        "isOptional": true,
        "cardinality": "SINGLE",
        "valuesMinCount": 0,
        "valuesMaxCount": 1,
        "isUnique": false,
        "isIndexable": false,
        "includeInNotification": false,
        "searchWeight": -1
    }
],
"relationshipCategory": "ASSOCIATION",
"propagateTags": "NONE",
"endDef1": \{
    "type": "custom_dataset",
    "name": "fields",
    "isContainer": false,
    "cardinality": "SET",
    "isLegacyAttribute": false
},
"endDef2": \{
    "type": "custom_field",
    "name": "datasets",
    "isContainer": false,
    "cardinality": "SET",
    "isLegacyAttribute": false
}}}

}

Now, I am trying to create a relationship between two types while defining an Entity for either type like

 

{{{
"entities": [
    \{
        "typeName": "custom_field",
        "createdBy": "admin",
        "guid": -1000,
        "attributes": {
            "name": "type",
            "datasets": [
                {
                    "guid": "-200",
                    "typeName": "custom_dataset"
                }
            ]
        },
        "classifications": [],
        
    }
],
"referredEntities": \{
    "-200": {
        "guid": "-200",
        "typeName": "custome_dataset",
        "relationshipAttributes" : {"LinkInformation": "key"},
        
        "attributes": \{
            "qualifiedName": "test"
        }
    }
}}}

}

Through, while executing this, I don't see any error and entities are created but {{LinkInformation}} is null by simply doing a search by {{GUID}} for entities.

 

{{...
"relationshipAttributes": \{
                    "typeName": "field_assignment",
                    "attributes": {
                        "LinkInformation": null
                    }
                }
...}}

I am not able to find a good documentation anywhere for this. Can anyone help?
