Getting your app to support Web Intents on Chrome
Chrome Dev and Canary (18+) now support Web Intents! Currently, intent registration is done via the Chrome apps manifest (not the intent tag) to allow the user agent to determine available services (including those on the local network or external native apps). The manifest entry specifies the supported action, data types, title, and path. Client-side code remains the same. Future support for declaring capabilities directly through HTML with the Intent tag is planned.
