GWGI need a good name for a function that looks at the mf2 properties of a post and returns the elements necessary to generate a link preview of the item being referenced(bookmark URL, check-in data, etc).
GWGRight now, I store everything in the wrong place. It should be nested properties under in-reply-to or bookmark-of, etc instead of in a separate area.
sebselBut then I use a function I believe I called 'lookup' or 'fetch', which looks at that dictionary for the URL, and if it's not there, it grabs it from the external source and stores it in the dictionary.
