 So Powalco is the platform of the Boulogne government. It's a project launched by the Boulogne government to synchronize the activities between the utility companies, let's say Petron, the cities and communes, and the government. So we know quite something about roadworks in Belgium. I don't know, but a large part of the roadworks, information of the roadworks ongoing in Belgium pass through our systems, which is also a fundamental basis. What we also saw, that this is a very distributed landscape. So there are many different solutions, many different proprietary solutions. And this talk, mainly by Bert, is in this talk, we want to share some ideas on how this information could be made available so that a more common benefit could emerge. So Bert, please, can you explain it? OK. So you all know this place that you are in the public space and you're traveling and walking around. And then if you look to, you come on the street, then you interact with each other. And you start interacting. That you have a builder who is doing some work. So there's a cyclist, you go to your work. You do some, you try to build the utility men, try to realize a new road or a new line. You have the public transport. You have the government in the whole, a local, regional, federal, European government. That's all interacting in the public space to do something to improve the situation. But as a consequence, if you are in that space, you get a lot of emotions. So when you're on the road, you might be really frustrated because there is something blocking you going around to go to take the cross-path here, cyclist. Or the worker might be frustrated and stressed that he doesn't get it on time, the work done, because he gets a premium, or the work doesn't work like that. Or you might be happy that the new bridge is coming and that you have in the future a shorter way back to your work. So that's, it raises a lot of sentiments when it works. And of course, you can deal with various ways with that. And this is a YouTube video on Mr. Bean, who has a lot of hindrance on the road works nearby and he finally finds the solution, namely giving those people, and his work is a good meal so that they are silent and he can sleep. So we have a lot to it. Of course, if you take from a distance as an information and as data, then you see that there are lots of actors in the public space. And they interact with each other. So it is, if you look to that kind of what they call the professional area, you have the government who has to say you can do this work for this place, et cetera. You have the utilities who pull the cables for gas, electricity, internet. You have the public transports going around in it. You have the emergency services that want to go from one place to another to when something happens. And you have, of course, the builders that actually conduct the work and to realize it. But they are not the only ones who interact in it. So of course, yourself, as a person, when you go back and forth in school or you be at home, as well in a working context or related to the context, you go on the road, you go in this public space and you can try to get the job done. And in order to improve that, and this is what Astéan already mentioned with Poalco, the governments want to realize, let's say, an improvement of synergy by putting a central system. And we actually have three in Belgium, one for each region, people that flounders Osears in Brussels and Poalco in Malonia. And the objective is all the same, namely, improve the interaction on the professional sites and then outside effects, you improve the interaction, you reduce the hindrance for the normal people on the work and on the road. Now, if you want to do that, you have two things to do. First of all, you have to build an IT system, so you have to create a digital form of the reality. You have to say what is a road, you have to say what is a bridge, what is a cable, you have to denote all these things. And secondly, you have to understand, and that's what Astéan already mentioned, is that this is a multi-actor process, so it's not a single system that you can build on your own, you have to know that this is an interaction between many actors and they have different visions and so on. In the end, if you can create that, then you can work on the synergy so that you get less hindrance. Now, the following slides are taking a step back and say, look, is the public space that's open for everybody, everybody's interacting, also open data, so it's a digital representation, if we look to that, if that is that as well as public as the public space is. And these are following the three aspects that you can find several on the open data aspects. So open data, availability and accessibility, if you look to that, you will see that the Flemish government has made the data in Heapwood available. There's West API, there's a Geographical Service, you can even have a UI for polishing on it. The volume government, yeah, that's not yet on the current roadmap. So we talked to them, we gave the incentive, look, you have to take this into account, but yeah, not yet active to the public sector, to the public, and Ozeer is roughly similar in sense of focused on the professions only. If you looked at the usability, the only one we can talk about in that level is that the keep of data is available on the CC heroes, essentially, you can reuse it freely and you can do whatever you want. And finally, if you look at the participation from the perspective of open data, this is a participation mostly oriented towards professionals. So professionals have easy access to it, but the general public, well, site-wise informed about it, they have access to this information, but not directly, they are not indirectly informed about this. And how does this come, this is weird. And now look what you can do or what we are the challenges from the perspective of these publishers. And one of the things is that open data is a form of a broadcast model. So you don't know who is going to capture the data. And that's a very challenging thing for a publisher for the one who owns the data. Certainly, if you know that it's over time, actually, the number of channels and hardware places where you have to deliver the data is growing. It's only the hardware, it's as well the software channels. So if you want to have it on your navigation app or on a Twitter feed or a web application, instead of as a publisher, as the owner of the data, why do I have to publish? How I have to make it available that the person who is working or going on the public space gets the information at the right moment, at the right time. And at the same time, they're faced with a question for how to a broadcast, because there are many ways that you can publish the data in a way that it's suitable and how do I make the match? And so that's the challenge that the owner of the data has to do. The other thing is that there are certain barriers that we have to look at for this thing in this space. Namely that if you have the data, then it's typically blocked by territory. So you find the road works in Flanders, let's cover this, Ozeerys, is in the Brussels region, a block over here. So if we take the road from Leuven to Louvre-Leneuve today and you go over Brussels or the highway and you pass through all the three and actually you need to treat the combined, you know what are the road maps. So you need to get access to all the data in order to have an iterating in Belgium to take into account that. And so that's a limit that we have to be aware of and that we should try to resolve. And the other thing is that the information that those systems, for all core people and so on, are publishing is only about plant activities. So it means that this is data where somebody has talked front. Okay, in six weeks from now, I will drill there, open up the road and I'll do something. Well, this is not all the activities that are annoying or giving you stress or making the activities on the roads difficult. There are kind of occasional activities. I didn't find the better word, but it's kind of exceptional transport, for instance, driving around. Yeah, yeah, you're blocked by it. How do you deal with that? Or even worse, so really emergency things, a big hole that comes like last year, Brussels, all the sudden pop, a big hole in the roads. How do you deal with that? And all of a sudden, all this information, if you go back to the software or the channels as a person that you want to be informed in navigation application, wants to know that in order to do something. So it's really challenging. That's okay, you cover this, but this is as well important. And the solution or at least one part of the solution is interoperability for me. So why? Because with interoperability, we can do certain things. And for me, key in interoperability is that public identifiers. Really, everything starts for me with, associating with the information of public identifiers. And if you do that, you do a lot. You make it available for everyone, but it facilitates internal use because at least over the systems, even in the professional space, if you were there, you would communicate already, but it's as well beneficial for everybody. And furthermore, if it's resolvable, you can create data hopping, data API hopping, I mean. So you can go from one API to the other API using the identifier. And it doesn't matter if it's one is in the linked data format and the other one is in the JSON format and third one is in the XML, you are able to go from one API to the other API. And that's the key of a public identifier. And that makes it important for interoperability. So as a side effect, in this public space, that's kind of a nice one. If you would do say, okay, I create public identifiers for roadworks. Okay, what I need to do, typically you start the next thing is, okay, I need some public vocabulary or I need to talk about what this actually is. That's what this identifier is not sufficient. You start to shift your mind to what is the vocabulary about it. Okay, when you have done that, well, you will identify easily, well, you probably need public identifiers for addresses because you want to really place where the roadwork is nearly located. Well, for the addresses, again, we need some vocabulary on it. And this goes on. You have for organizations, who did it, you want to talk about that, or who is impacted and roads and so on. So you start kind of having, actually spreading the information in a public space. And this is a look, if you look back from open data perspective, if you start doing this for roadworks, all of a sudden, the whole space becomes digitally open data, with not with the intention to be open data, but with the intention to make it easy for the professional services, integral, connected by the data. I'll give you some ideas what you can do with it. And I group them in two blocks. One is inform the citizen and the other block is citizen engagement because they are too different. The first one is get the information to the citizen. Okay. What you can do is make the information available like electronic news and electronic newspaper. And we did a small part with a combination of the Flemish government as the owner of hipots. We stand for us having the utility sector and having a follow-up system for the roadworks for that utility, like tail end approximation as well. And finally we have Postbus, which is an electronic newspaper that you can follow. So you can subscribe yourself to news that's happening locally in your area. That's it. And what happens now is if you combine those information is that a utility work like Electrabell, might say, okay, look, please, I'm going to do another work on the electricity here. Announces it in hipots. There is an hindrance and effect. Define, say, okay, it's on this street or so on. It's also saying it's this scope. And actually, and this is taken into the Postbus as a news article so that if you live there and you look there and say, okay, now it's happening. I can show it live, but just for the screenshots, it's easier. In the end, you get a news thing saying, okay, it's in Dutch, I'm hoping I can use post it three days ago. And it's meant, it says, okay, the hipot system. Announces that there will be works from 12.3 till 24 of March in Gothenburg, the Zarenstrasse, and it was doing electricity, cable television, public light. So you have some news now, as a person, what's happening over there? So you're not informed by some, yeah, some late or something that is placed over there. You're actually informed here by your newspaper on the public works and what's happening. What is challenging still on this one is that if you want to use this data, you have to, in the newspaper, you have to edit because news articles are not the technical mentioning that you find in hipot, you have to do some editorial work into it. So this kinds of feedback loop, if you want to make the hipot data as well available for news articles, maybe there should be some editorial feedback. But what you can do more with this public identifier. So you have a world work, typically, for a long work, you have to have this science up front and you say, okay, look, this work happens at this point in time for so long and this is the one tour that you have to take and it has to be published in this thing. Now, this is typically not up to date. So it's made once and if that changes because it has that weather, then it will be extended a period and somebody has to go there and put some stick of tape over it with just reverse queue encoding. If we know the coordinates, we can ask actually what's the road work nearby and we can create exactly out of the hipot data and protocol data this time that all that information is over there. So electronic use of that is easy to do. The other one is that this is a typical example of the first open data apps fix my streets. I think everybody in the open data should know fix my streets. So Brussels has installed it, fix my streets, report the instances within the Brussels police, public space and improve your environment and it really works, the people are using it. So that's very great. However, if you read the conditions and what works on it, then you will, in terms, and you will see that they say, okay, if you report something that is on the road of the Brussels Charest or the Flemish Charest, we cannot handle it. We will close your issue. That's a really statement over there. You can find, actually, this one is the case, you can find, okay, we have reported it to the Brussels Charest, Brussels region and we close your issue. Thank you for your information and all the communication is done. Now, Flanders has a program where they want to do interoperability on their base research trees and one of the aspects where they have challenges with is how you can bring feedback to it and they want to create something generic feedback mechanism to it and calls in Dutch genericky terugmeldfaciliteit. And what does it do? It actually connects feedback to one data identifier and it has the ambition, if you write, say, about this data, this location, this address, this road work, I have some comment to give. It will go to a system, say, okay, I will find out for you to whom is responsible for this thing. You don't now have to know a citizen who is responsible for it. We have a system that will get to the system, to the responsible and then you have a general follow-up to all the whole organization of the public government. And that thing actually implements, I think, my streets, both lines. So we don't have to implement it in a separate process, although very nicely styled and working as well. You actually get it for free out of the quality control that the government wants to realize for all its data. And that actually ends my talk. The public space, I want to give you with you, is actually, as such, a very rich domain and the data itself is actually as rich already as it is in the real world. And we have seen, by my example, that's actually the motivation to improve the interaction to the professional space, actually as well improves interaction to the open data. If you look to it in its own. So if that is going on for you, that is very good. And finally, if we really want to have open data, this aspect of interoperability, if you do it and you take it into account in this activity, then you get a very nice flow out. Do you have time for questions? So... You talked about, oh, welcome, oh, welcome. Why the data, I needed them here. Why the data are not open data in the midst of it? We asked that to the officials, the contract leaders over there, and they say, okay, we didn't talk that this was immediately of our mission. We first focused on the professional activity, getting that right. And the open data, okay, there's not kind of something needed on the roadmap. And so we, as 10 forces in contract, they say, look, you have to take that into consideration. So we brought it to the table, but ultimately, we are not the decision makers that will happen in the way that we would like. We only can advise. And can one city, for example, share the data that they have for Wauco? Probably it can, because... So it could be a city. A principle, I think, because ultimately, you can say ownership relies to the city and therefore they can share. That's at least my opinion, but I don't know if there might be a fight on it, but in principle, that's good. I can give you a small update about Ozees. We are working on Ozees 2, where open data is completely... It's part of the deal. Super. So... And a small correction on FixMyStreets, as soon as it's both on regional and communal areas, there is a feedback. Okay, but it's in your terms, you're right, still. So you have to update your tools. We'll check that. Yeah. One more question. Are the data available from the API on Ozees or for Wauco, for example? Because to share the data on electronic news, it's interesting, but also use this data in other contexts, because you were talking about utilities, for example. So we could use this data in other contexts and even Waze, for example, for the best project. That's for instance, what I give... Well, the open data is coming from Ozees, for Wauco at this moment. It's on discussion. For Gipot, it's open. But it's API? API, yes. And it's fully API there, as well. But if you look for other examples, for instance, you can have the Flemish government that has calculated hundreds of companies nearby. That is an API call that you can use to say, okay, which other impacted companies for a work that you can ask. That's all side effects.
