View

The view intent is designed to give applications the ability to offer a simple mechanism to view data in their application.

An action that can handle view could be anything that the user has installed, including and not limited to specialist image tools or audio players.

The "View" protocol is intended to be a lightweight view facility.

Registration

<intent
  action="http://webintents.org/view" 
  type="image/*" 
  href="view.html"
 />

action: Required. Must be http://webintents.org/view
type: Optional. Types are a filter
href: Optional. If specified, it will point to the action that is loaded when the user chooses the service. If undefined, use the current page.

window.navigator.startActivity(intent);

Data Formats

Clients and services can only interact with each other if the both support the same intent AND the same data type. Data-types can be any arbitary string, but it is expected that client and service will pass the same data if they both agree to support the protocol.
