URL Preview

URL preview allows users decide quickly whether to follow a link by displaying a thumbnail preview for URLs.

Thumbnails are renderings of rich metadata to point to accessible HTML resources in microblog messages in the Activity Stream.

URL preview supports the following OpenGraph metadata:
  • Title
  • Description
  • An image representation of the resource
Metadata is obtained from the following contexts:
  • User input focus (as the user types the url in the microblog message)
  • Activity Stream (events about microblogs)
  • Status Updates
