Embedding nodes inside a list of list does not seems to work.

[miahmohd]

I have a json-ld that contains a 2d list, and I'm struggling to frame it correctly.

The flattened (input) json:

[
    {
        "@id":"http://example.com/resource/Conversation1",
        "@type":[
            "http://example.com/ontology/Conversation"
        ],
        "http://example.com/ontology/triggers":[
            {
                "@list":[
                    {
                        "@id":"http://example.com/resource/Trigger1"
                    }
                ]
            }
        ]
    },
    {
        "@id":"http://example.com/resource/Trigger1",
        "@type":[
            "http://example.com/ontology/Trigger"
        ],
        "http://example.com/ontology/formula":[
            {
                "@list":[
                    {
                        "@list":[
                            {
                                "@id":"http://example.com/resource/pred1"
                            },
                            {
                                "@id":"http://example.com/resource/pred2"
                            }
                        ]
                    },
                    {
                        "@list":[
                            {
                                "@id":"http://example.com/resource/pred3"
                            }
                        ]
                    }
                ]
            }
        ],
        "http://example.com/ontology/next":[
            {
                "@value":"Next"
            }
        ]
    },
    {
        "@id":"http://example.com/resource/pred1",
        "@type":[
            "http://example.com/ontology/PredType"
        ],
        "http://example.com/ontology/negate":[
            {
                "@value":false
            }
        ]
    },
    {
        "@id":"http://example.com/resource/pred2",
        "@type":[
            "http://example.com/ontology/PredType"
        ],
        "http://example.com/ontology/negate":[
            {
                "@value":true
            }
        ]
    },
    {
        "@id":"http://example.com/resource/pred3",
        "@type":[
            "http://example.com/ontology/PredType"
        ],
        "http://example.com/ontology/negate":[
            {
                "@value":false
            }
        ]
    }
]

The frame I used:

{
    "@context":{
        "@version":1.1,
        "@base":"http://example.com/resource/",
        "@vocab":"http://example.com/ontology/",
        "formula":{
            "@container":"@list"
        },
        "triggers":{
            "@container":"@list"
        }
    },
    "@type":"Conversation",
    "triggers":{
        "@type":"Trigger",
        "formula":{
            "@embed":"@always",
            "@type":"PredType"
        }
    }
}

The output generated:

{
    "@context":{
        "@version":1.1,
        "@base":"http://example.com/resource/",
        "@vocab":"http://example.com/ontology/",
        "formula":{
            "@container":"@list"
        },
        "triggers":{
            "@container":"@list"
        }
    },
    "@id":"Conversation1",
    "@type":"Conversation",
    "triggers":[
        {
            "@id":"Trigger1",
            "@type":"Trigger",
            "formula":[
                [
                    {
                        "@id":"pred1"
                    },
                    {
                        "@id":"pred2"
                    }
                ],
                [
                    {
                        "@id":"pred3"
                    }
                ]
            ],
            "next":"Next"
        }
    ]
}

The output I want is:

{
    "@context":{
        "@version":1.1,
        "@base":"http://example.com/resource/",
        "@vocab":"http://example.com/ontology/",
        "formula":{
            "@container":"@list"
        },
        "triggers":{
            "@container":"@list"
        }
    },
    "@id":"Conversation1",
    "@type":"Conversation",
    "triggers":[
        {
            "@id":"Trigger1",
            "@type":"Trigger",
            "next":"Next",
            "formula":[
                [
                    {
                        "@id":"pred1",
                        "@type":"PredType",
                        "negate":false
                    },
                    {
                        "@id":"pred2",
                        "@type":"PredType",
                        "negate":true
                    }
                ],
                [
                    {
                        "@id":"pred3",
                        "@type":"PredType",
                        "negate":false
                    }
                ]
            ]
        }
    ]
}

I can't find a way to embed the nodes inside formula properly, how can I make it work?
