 So then, on to these physical elements. This is really something new for many enterprise architects, because the physical world has largely been out of scope, and I think that's still the case for Togav. It addresses the IT world, but it doesn't concern the physical world, and I think that should be something we have to have a closer look at as enterprise architects. So what we did is we extended this technology layer with elements for modeling the physical world. And you'll see the elements in the next slide. So that supports things like manufacturing, logistics, all kinds of transport, energy, all kinds of physical environments. Healthcare is also an example that Ivor will address at the end. Increasingly, you see, of course, the integration of healthcare and IT as well. All kinds of devices starting from, say, your Fitbit that tracks your health, tracks your behavior, and that's really what we want to model as well. It's not just IT systems. IT is intertwined with the physical world in various ways, and we really need to be able to express that as architects. So this is very, well, I think very important for people looking at technology development like the Internet of Things. It will help you in modeling that. And we have done it in such a way that it is very closely integrated. It's not a separate set of concepts, but we use the existing concept node in Archimedes. You might know that. It's the sort of abstract high-level concepts for modeling in the technology layer, for modeling active structure in the technology layer. But we also added concepts that extend node, you know, the existing concepts like device, which is a specialization of node, but we will have a concept called equipment for physical equipment in the same way that we have device for IT equipment. And they both are extensions of nodes, so you can easily create combined nodes that consist of both IT and physical elements, and in that way express things like computer control machinery, Internet of Things, et cetera. And we also reuse the existing behavior elements. So we didn't add any other behavior elements to these physical set of concepts. We reuse the physical behavior, the technology behavior elements that we already have so that you can have integrated technology functions or technology processes for both the IT and the physical world. Well, onto a small example, well, the concepts and then onto a small example. And first of all, we have added a concept called facility. And a facility that's a physical structure or environment, typically an environment where you will put your equipment. So equipment is the next physical element. That can be any kind of physical machinery, instruments that can be used to create or store or move or transform materials, and material that will of course be the next concept. Yesterday I had a discussion with someone who asked me, well, if you're a farmer, how would you model your horse? Well, a horse would be equipment as well. Like a tractor is equipment, a horse would be equipment. It might be a bit strange, but you could even use it in that area. But you can model all kinds of smart devices with this, like in healthcare or like a black box in your car, et cetera. So facility, you can see the symbol, it looks like a factory with any kind of facility. You can have a laboratory or as we had a discussion in the Artimate Forum, if you're a mushroom grower, the grotto in which you grow the mushrooms, that could be a facility as well. Then we have material. Material is tangible physical matter or physical elements. So anything you create or build with physical matter is modeled like material. It can also be stuff like fuel, that's also material. And of course we need a way to transport that. So we have also added a concept called distribution network. And that's a way to transport physical materials or energy in much the same way that we have a communication network for this transporting information, bits and bytes. And this is also the reason that we renamed the communication path concept to just path, because distribution network is a specialization of path like or is a realization of path, just like a communication network is a realization of a path. So path is now the generic concept like node is the generic concept for these connections. So we slightly extended the meaning as well, so you can exchange more than just data, you can also exchange material. So just to show you a small example, very simple of a manufacturing plant with an assembly line inside that assembles vehicle telematics appliances. From two different kinds of material, pre-assembled circuit board and internal antenna, those are put together and then you create this appliance. These appliances then are distributed by a local and national distribution center and a distribution network. Well, overseas shipping is one and local tracking is the other. So these are the concepts really just the new concepts that we added. In this picture, there's no behavior as I mentioned before. We didn't add any other behavior concepts. So that's still the same technology behavior we have. So you can easily model say the assembly process if you want to have the behavior of the assembly line. So that's the physical set of concepts that we added.
