     31 //    action            Name of action provided by the service.
     32 //    type              MIME type of data accepted by the service.
     33 //    title             Title for the service page
     34 //    disposition       Either 'window' or 'inline' disposition.
     35 //
     36 // Web Intent Services are uniquely identified by the <service_url,action,type>
     37 // tuple.

     41 // web_intents_defaults
     42 //    action            Intent action for this default.
     43 //    type              Intent type for this default.
     44 //    url_prefix        URL prefix for which the default is invoked.
     45 //    user_date         Epoch time when the user made this default.
     46 //    suppression       Set if the default is (temporarily) suppressed.
     47 //    service_url       The URL of a service in the web_intents table.
     48 //    extension_url     The URL for an extension handling intents.
     49 //
     50 // The defaults are scoped by action, then type, then url prefix.
