Imported nested attributes

[andy-symonds]

Hi TypeDB-Loaders,
Thank you for open-sourcing such a great tool!

I cannot find any documentation on importing attributes of attributes. The appendAttribute functionality only is documented to work for entities and relations (that I can see). Please could you tell me if this is possible or if it is on the road map?

Thinking if something like the below is possible in the TypeDB-Loader config file, where entityA owns attributeA, and attributeA owns attributeB.

"entities": {
    "entityA": {
        "data": [
            "mydata.csv"
        ],
        "insert": {
            "entity": "entityA",
            "ownerships": [
                {
                    "attribute": "attributeA",
                    "column": "attributeA",
                    "ownerships": [
                        {
                            "attribute": "attributeB",
                            "column": "attributeB"
                        }
                    ]
                }
            ]
        }
    }

This is of course possible directly in TypeQL, with something like (if the entityA and attributeA are already loaded in):

match $a isa attributeA; $a "Foo";
insert $a has attributeB "Bar";

It would just be lovely to do it all using TypeDB Loader :)

Many thanks in advance!
Andy

Hi -
There's no reason it shouldn't be done, we'll have to get around to implementing it :) the syntax should already support it in the "attributes" section actually...

Hi @flyingsilverfin,
Thanks for confirming that it is possible :) Interested that the syntax should already be supported in "attributes" section.

I am continuing to play around with the syntax to see if I can match and then insert attributes of attributes (no luck so far). If you have any pointers/suggestions please let me know :)
