Interface

• general control: (type: general)

  • end user's mobile/web communicate with device

    • JSON-LD

      • schema

          schema: {
            '@type': 'general',
            '@context': {
              '門A': {
                 “@events” : { // 聽到事件
                 “bell”: null,
                 “key”: {
                    “valid” : “boolean”
                  }

                }
            }
          }
        

        宣告物體組成: Door schema js: wot.schema({}) json: { “@events” : { “bell”: null, “key”: { “valid” : “boolean” } }, “@properties” : { “is_open” : “boolean” }, “@actions” : { “unlock” : null } } 假設現在一共有門A, 則全部schema: js: wot.register('門A', 'Door'); wot.register('門B', 'Door'); json: { @context : { @base=”http://…. }, “@dependencies” : { “door” : “門A”, “light” : “switch12” } }

        client: 端發出去 var 門A = wot.register('門A', 'Door'); 門A.onEvents('unlock', function() { });

        json-ld send:

          {
            name: 'data channel id',
            type: 'general',
            門A: {

client 端傳送進去規格

燒進去版子的content:

  var wot = require('wot');
  var cylon = require('cylon');

  wot.on('led', function(data) {
    if ( Number(data) === 1 ) {

    } else {

    }
  }
  })
