Essentially, BIRT 360 (the iServer dashboard product) is 100% Google gadget compliant. You can link gadgets from different data sets or data objects in an iServer dashboard by using the Google Gadget Framework publication/subscription feature.

The functionality allows one gadget to 'publish' information to a channel and then any 'subscribed' gadget to that channel will call a callback method in the subscriber when the 'publish' occurs, passing the information to the callback. In the callback you can decide what to do with the information, for example run a report using the information as the parameter values, or filter a chart.

Most of the time this means that you have to create a Google Gadget wrapper to house your code (really just an XML representation of the gadget). Then, when creating a new gadget in 360, go to extras->import and import the gadget. The XML gadget file needs to be on a web resource that is available to the Information Console machine.

I've attached two XML files. One publishes, and one subscribes. The subscriber gadget actually uses Actuate JSAPI to drop in BIRT content, and then also uses JSAPI to filter a table in the report that is being displayed in the gadget using the value that was published.
