web service
✓ Service – Example - Look photo-face book-
human vs machine
✓ Mashing API- Multiple API’s – google map
✓ Scraping – has data- convert to API – website
service
✓ Legalities

✓ Implementing the API
✓ An API defines the messages that are sent from
client to server and from server to client.
✓ Most common standards-
✓ REST –access a set of web URL
✓ JSON-RPC- Single web URL
✓ XML-RPC- use XML instead of JSON
✓ Simple Object Access Protocol (SOAP)- XML –
additional Layers

✓ Traditional – HTTP- Request – Response
✓ polling and the so-called “Comet” technologies.
✓ And then, in the section on non-HTTP protocols,
MQTT, XMPP, and CoAP offer alternative
solutions.
✓ Long polling – unidirectional
✓ HTML5 Web Sockets (Bidirectional)
✓ Scaling

✓ MQTT – Publish/Subscribe – Broker
✓ MQTT-S-Zigbee
✓ XMPP-EXTENSIBLE MESSAGING AND PRESENCE
PROTOCOL
✓ XMPP – Messaging Protocol – Instant message service
✓ Constrained Application Protocol (CoAP) – UDP
