Looks like @TwitterAPI has been keeping very busy. Raffi Krikorian, Twitter Developer, unveiled today Twitter Annotations – “twannotations”.
Annotations – a note of explanation or comment added to a text.
According to Raffi, Twannotations will bring a context perspective and will add to increased search and streaming ability. The way he’s described the Twannotations looks like is that every tweet annotation will have a “type,” and each type can have several attributes – types can be repeated but attributes cannot, and these will be publicly visible unless you set your account to private. Interesting fact, Twitter is not going to validate Twannotations, but there will be an annotations explorer where one can see the treending annotations, stats, and developers ‘wiki’ zone.
Here’s the presentation:
