Machine-to-machine Communication

• M2M has been around for a long time
  • all major Web application use it in one way or other...
• Two broad approaches emerge:
  1. procedural based
     • active entities are made public
     • revival of distributed computing
     • this is the area of Web Services
  2. data based
     • (passive) metadata is added to resources
     • other entities can read and process it
     • this is the area of the Semantic Web
• Ultimate goal: improved user experience
