For multisite, you can work with both sites and languages. A site can hold a language, and a language can be held by multiple sites. Fields ID,title, url and image are required. Site and language names have no standard, so you can choose your own codes.

{
    "id": "ID",
    "ti": "Title",
    "u": "Url",
    "i": "Image",
    "languages": {
        "ca": {
            "ti": "Title in catalan",
            "d": "Description in catalan"
        },
        "es": {
            "ti": "Title in spanish",
            "d": "Description in spanish"
        }
    },
    "sites": {
        "site_in_cat": {
            "language": "ca",
            "p": 1.32,
            "p_c": "1.32 €",
            "op": 2.01,
            "op_c": "2.01 €"
        },
        "site_in_esp": {
            "language": "es",
            "p": 4.32,
            "p_c": "USD 4.32",
            "op": 5.01,
            "op_c": "USD 5.01"
        }
    }
}

Using languages is not a must, and should be used when some sites share the same language. The main goal for languages is to reduce both the feed and the index sizes.

{
    "id": "ID",
    "ti": "Title",
    "u": "Url",
    "i": "Image",
    "sites": {
        "site_in_cat": {
            "ti": "Title in catalan",
            "d": "Description in catalan",
            "language": "ca",
            "p": 1.32,
            "p_c": "1.32 €",
            "op": 2.01,
            "op_c": "2.01 €"
        },
        "site_in_esp": {
            "ti": "Title in spanish",
            "d": "Description in spanish",
            "p": 4.32,
            "p_c": "USD 4.32",
            "op": 5.01,
            "op_c": "USD 5.01"
        }
    }
}

The feed will be served in JSONL format. As simple as a file when you write a json representation of an item. Important. Each line must represent one item. This means that break lines must be encoded.
