SData 2.0 How to assign relation (for instance email to a person)

Hi,

I am able to list emails for a person like this:

→ curl -H "Authorization: Basic $AUTH" "http://192.168.22.198/sdata/crmj/sagecrm2/-/Person('1502')/Email" | jq
{
  "$url": "http://msedgewin10/sdata/crmj/sagecrm2/-/Person('1502')/Email?startindex=1&count=10",
  "$first": "http://msedgewin10/sdata/crmj/sagecrm2/-/Person('1502')/Email?startindex=1&count=10",
  "$last": "http://msedgewin10/sdata/crmj/sagecrm2/-/Person('1502')/Email?startindex=1&count=10",
  "$totalResults": 1,
  "$startIndex": 1,
  "$itemsPerPage": 10,
  "$resources": [
    {
      "$key": 2736,
      "$title": "",
      "$url": "http://msedgewin10/sdata/crmj/sagecrm2/-/Email('2736')",
      "Emai_EmailId": 2736,
      "emai_IntForeignID": null,
      "emai_intlastsyncdate": null,
      "Emai_EmailAddress": "[email protected]",
      "emai_IntId": null,
      "emai_promote": false,
      "Company": {
        "$url": {
          "Association": "http://msedgewin10/sdata/crmj/sagecrm2/-/Email('2736')/Company?startindex=1&count=10"
        }
      },
      "Account": {
        "$url": {
          "Association": "http://msedgewin10/sdata/crmj/sagecrm2/-/Email('2736')/Account?startindex=1&count=10"
        }
      },
      "Person": {
        "$url": {
          "Association": "http://msedgewin10/sdata/crmj/sagecrm2/-/Email('2736')/Person?startindex=1&count=10"
        }
      }
    }
  ]
}

I'm also able to create email like this:

→ curl -H "Authorization: Basic $AUTH" "http://192.168.22.198/sdata/crmj/sagecrm2/-/Email" -X POST -H "Content-Type: application/json;vnd.sage=sdata" -d '{"Emai_EmailAddress":"[email protected]"}'
{"$key":4190,"Emai_EmailAddress":"[email protected]"}

But I don't know how to create email assigned to a person. I tried this:

→ curl -H "Authorization: Basic $AUTH" "http://192.168.22.198/sdata/crmj/sagecrm2/-/Person('1502')/Email" -X POST -H "Content-Type: application/json;vnd.sage=sdata" -d '{"Emai_EmailAddress":"[email protected]"}'

As you see it doesn't work. What I'm doing wrong?

Also, is there a way to create person and emails using one API call?
