At a high level:

• could accept a string that represents a URL (https/ipfs/etc)
• could accept an inscription hash or inscription number
• could be used for displaying SEO-style data: title + image + link
• could accept an array instead of a single value

In The Tripolar Moment we also explored inscribing images for the article, then returning them via an API or similar.
