Did you know that you can expose your Opera Widgets to your website visitors the same way you expose feeds, using autodiscovery? Didn’t think so, since this is the most underpublished fact about widgets. Anyway, exposing your widget is simple enough: Simply add a relevant
link element to your document’s head section:
<link rel="alternate" type="application/x-opera-widgets" href="http://my.opera.com/grafio/widgets/get.pl?id=4647" />
When a page has an attached widget like this, Opera will display a widget icon in the address bar:
!http://virtuelvis.com/download/2006/07/widget-autodiscovery.png (The Widget autodiscovery icon is displayed on the address bar)!
If you want to start using autodiscovery, the value of the
rel attribute must be alternate, and the value of the
type attribute must be application/x-opera-widgets. Please do not not treat the previous sentence as spec text, because it’s definetly not.
