[SSG][Metadata] AlternateURLs/Languages ; OpenGraphMetadata

[gustaveWPM]

Hello!

In Next, using App Router, we can specify a Metadata object.

https://nextjs.org/docs/app/building-your-application/optimizing/metadata In this Metadata object, we have a alternates field, which is defined as: alternates?: null | AlternateURLs;

If we give a look inside AlternateURLs, then, we can see this:

export type AlternateURLs = {
    canonical?: null | string | URL | AlternateLinkDescriptor;
    languages?: Languages<null | string | URL | AlternateLinkDescriptor[]>;
    media?: {
        [media: string]: null | string | URL | AlternateLinkDescriptor[];
    };
    types?: {
        [types: string]: null | string | URL | AlternateLinkDescriptor[];
    };
};

The languages field is interesting.

I would like to know if Next International should provide helpers for this.

Same concern for OpenGraphMetadata, which has locale and alternateLocale fields.
