"Via" URLs in items

[letrastudio]

I'd love to see something like Atom's <link rel="via">.

Proposal:

• via_url (very optional, string) is a URL pointing to the source of the information provided in the item. This is especially useful for linkblogs. If url links to where you’re talking about a thing, and external_url links to the thing you’re talking about, then via_url links to where you heard about it.

Hadn't seen your issue before. You are right that both are aiming to solve the same problem, but taking different approaches.

I think "via" is a better name than "source", as it's more immediatly identifiable (that's why I hadn't found your issue). And this simpler implementation — a single URL string instead of an object — seems more aligned with the rest of the spec. Metadata can be retrieved from the destination URL directly, so I see no need to store it in the feed JSON.
