    Arko,

    Where a Card contains Ports we may represent a Port as:

    {
       "id": "abcdef",
       "@type": "Port",
       "@baseType": "Resource",
       ...
       "resourceRelationship": [
          {
             "@type": "ResourceRelationship",
             "relationshipType": "contained",
             "resource": {
                "id": "uvwxyz"
                "@type": "ResourceRef",
                "@referredType": "Card",
                ...
             }
          }
       ]
    }​​

    In this case to query the resource inventory collection for Ports on a specific Card you could use:
    ​​​

    GET /resourceInventoryManagement/v4/resource?filter=resourceRelationship[?(@.resource.id='uvwxyz')]

    You could (also?) manage a "contains" relationship of the Card:

    {
       "id": "uvwxyz",
       "@type": "Card",
       "@baseType": "Resource",
       ...
       "resourceRelationship": [
          {
             "@type": "ResourceRelationship",
             "relationshipType": "contains",
             "resource": {
                "id": "abcdef"
                "@type": "ResourceRef",
                "@referredType": "Port",
                ...
             }
          },
          ...
       ]
    }​​


    If you want to get a partial representation of this Card containing just the related Ports:

    GET /resourceInventoryManagement/v4/resource/uvwxyz?fields=resourceRelationship[?(@.resource.@referredType='Port')]

    Thank you for the response. But I want to know the query format to retrieve list of ports available under the network element within all the cards

    Add the required relationships to the inventory and query them as I demonstarted.
