OPC UA Makes Machine-Centric Global Village Possible – Call for Sponsors

Object-Oriented Internet – Machines to Machine Meaningful Interoperability

It is said that we are or soon will be citizens of a global village – a world considered as a single community linked by telecommunications. All applications designed atop of network communication can be grouped as follows:

  • human-centric – applications where the information origin or information destination is an operator
  • machine-centric – applications where information creation, consumption, networking, and processing are achieved entirely without human interaction

A typical human-centric approach is web-service supporting, for example, online bank account management. In this case, it is essential that any uncertainty and necessity to make a decision can be relaxed by human interaction. Coordination of multi-robot behavior in a work-cell or autonomous cars entering a service area fulfills the machine-centric scenario. It is crucial that, in this case, any human interaction is impractical or even impossible. This interoperability scenario requires a machine to machine communication (M2M) demanding multi-vendor devices integration.

The human-centric global village is almost done. However, the machine-centric global village still needs design and development effort. Information and Communication Technology (ICT) has provided society with a vast variety of distributed machine-oriented applications including the meaningful Machine to Machine (M2M) communication targeting distributed mobile applications in the context of new emerging disciplines, i.e. Industry 4.0 (I40) and Internet of Things (IoT). However, it is a real challenge if the mentioned machines are provided by a vast variety of vendors. The real challenge we are facing is how to produce independently smart things (i.e. machines, devices, appliances, assets, etc.) to guarantee that they are plug and produce ready. There are no doubts, it requires standardization. I believe that while producing the machines in compliance with the OPC Unified Architecture this issue is relaxed by applying the following OPC UA standardized concepts:

  • Information Model – all about how to design a formal but mutually meaningful and shareable description of the considered process
  • Address Space – all about how to instantiate and expose to the network a life replica of the process providing real-time data according to the above-mentioned formal description

The standardization process may be "paper-driven" or "community-driven". In both cases, standardization is indispensable but not sufficient. Let me recall that the foundation for the human-centric global village is just the Internet Protocol defined in 1981 and derived from the academic abstract knowledge and practitioners’ concrete experience. It is worth stressing that it was published as an open-access document (RFC 791) and it has not been deprecated yet.

The open-access Object-Oriented Internet (OOI) umbrella project targets multi-vendor plug-and-produce machines interoperability scenarios targeting all aspects of the machine-centric global village concept aimed at providing reusable deliverables, training, best practice rules, prototyping, compliance testing and dissemination of valuable results.

I am a researcher who is passionate about applying knowledge and experience in building a machine-centric global village. Let’s build it with you and for you. To join our effort and create an organization context I have launched the Object-Oriented Internet Partnership Program.

Consider joining Object-Oriented Internet Partnership Program. Your participation is needed to make sure the work will continue as expected.

Why follow Object-Oriented Internet

To make real progress, I propose to focus on leveraging:

  • well-known concepts, e.g. Object-Oriented Programming (OOP), Service-Oriented Architecture (SOA), Data-Oriented Architecture (DOA), cloud computing, etc.
  • existing and emerging standards, e.g. OPC UA, AMQP, MQTT, etc.
  • academic knowledge and practitioners experience
  • available human-centric global village interoperability platforms, e.g. GitHub, WordPress, Research Gate, LinkedIn, Twitter, Gitter, etc.
  • loosely coupled research and development team of direct contributors

and contribute to the following call to actions

  • brainstorm ideas
  • collect requirements
  • collect existing solutions and deliverables
  • provide proof of concept
  • provide deliverables
  • create video curses
  • work on eBook
  • build up a loosely coupled team

Current list of projects covered by the OOI Partnership Program you may find here Pinned projects. There is a very important tool addressing all aspects of the OPC UA Information Model design and Address Space deployment. The tool Address Space Model Designer is maintained as the open-source public project on the GitHub. To get more visit the article OPC UA Makes Machine to Machine Meaningful Interoperability Possible.

Why follow me

I have 35+ years of experience in designing and deploying highly distributed applications having managed 100+ innovative projects for industry including aviation, heat engineering, power engineering, and mining. I am the author of

  • Process Observer concept and implementation
