Manu Sporny, who has been instrumental in JSON-LD’s development and is one of the authors of the draft, heralds the news here in his blog, noting that it means that Gmail now will be able to recognize people, places, events and a variety of other Linked Data objects, and that actions may be taken on the Linked Data objects embedded in an e-mail. “For example, if someone sends you an invitation to a party, you can do a single-click response on whether or not you’ll attend a party right from your inbox. Doing so will also create a reminder for the party in your calendar,” he writes.
