MapConfig Named Maps Extension

1. Purpose

This specification describes an extension for MapConfig 1.3.0 version.

2. Changes over specification

This extension introduces a new layer type so it's possible to use a Named Map by its name as a layer.

2.1 Named layers definition

{
    // REQUIRED
    // string, `named` is the only supported value
    type: "named",

    // REQUIRED
    // object, set `named` map layers configuration
    options: {

        // REQUIRED
        // string, the name for the Named Map to use
        name: "world_borders",

        // OPTIONAL
        // object, the replacement values for the Named Map's template placeholders
        // See https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/Map-API.md#instantiate-1 for more details
        config: {
            "color": "#000"
        },

        // OPTIONAL
        // string array, the authorized tokens in case the Named Map has auth method set to `token`
        // See https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/Map-API.md#named-maps-1 for more details
        auth_tokens: [
            "token1",
            "token2"
        ]
    }
}

2.2 Limitations

1. A Named Map will not allow to have named type layers inside their templates layergroup's layers definition.
2. A named layer does not allow Named Maps form other accounts, it's only possible to use Named Maps from the very same user account.
