Authentication: OpenID which is described here (http://zhenhua-guo.blogspot.com/2008/05/openid.html).

RESTful web services are used instead of SOAP-based web services. URL pattern used to access various resources is described here(http://zhenhua-guo.blogspot.com/2008/05/url-pattern-in-mashup.html).

At client side, Ajax is used to enhance user experience. Client side functionality is described here(http://zhenhua-guo.blogspot.com/2008/06/client-side-techniques.html).
