This is the fifth in my series of Web Integration Patterns. Check out the intro at this URL http://rollerweblogger.org/roller/entry/web_integration_patterns
Allow other web sites and applications to integrate your site into their web pages by providing an embeddable user interface, commonly known as a Gadget or Widget, which allows users to view and interact with your site in the context of other sites.
Easy to "consume"
And below is the Flickr Widget, which shows a random selection of my photos from Flickr. You can see these two Widgets in action on the front page of my blog. And, by the way, the Like, Tweet and +1 buttons on the right of this entry (when viewed on my blog site) are also Widgets.
Relatively easy to create
I'm not going to go into detail as there are already so many good resources on the web for learning about Widget crafting. For example, Alex Marandon wrote a pretty comprehensive blog post on creating Widgets covering basic issues like how to ensure that your widget code does not interfere with the page hosting the Widget, how to dynamically load resources and how to bypass browsers single-origin policy using JSON-P.
Widget and Gadget standards
That's it for Widgets and Gadgets. Next up: Feed-based Integration.
