  28 //
  29 // web_intents
  30 //    service_url       URL for service invocation.
  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.
  38 //
  39 // Also manages the defaults table:
  40 //
  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.
