A new intersting tool from Google
I just start to learn how it work but as a first impression for example will be very good for our blogs and for museums that can share in easy way calendars of events.
UPDATE (directly from Google Blog)
Last week, there was Google Calendar. This week, developers can start writing code that uses it. Enter the Google Calendar data API, which can be used to write external applications that query, create, and update Google Calendar events, so they’re available to Google Calendar users or other API-enabled applications.
My note: this change all things, complete interactivity between museums web sites and Google Calendar
