oembed - open embed format
oEmbed is an open format for embedding media from third-party providers, e.g. videos, pictures or tweets. It turns a URL into an embeddable representation of the media content. If, for example, a link to a video is shared on a blog or social network, it can automagically be turned into an embedded video. The talk starts with a summary of oembed considering both API provider and consumer. The second part focuses on how to turn a rails app into an oembed provider.
