 Hello, good afternoon. I hope I can match this by the level of my predecessor. I don't have movies, but I brought me a monument. It's a well known, it's the Atomium. I thought I had to start with the Atomium because it's the symbol of engineering, of science and of knowledge. And as you know this conference is organized by Open Knowledge. It is also the symbol of Brussels and Belgium and we are at the Open Belgium data conference. So another point to take it. And it is the landmark that every visitor that comes from abroad comes to Belgium who wants to see. So I'm talking today about touristic data. So again this image is on its place. And last but not least, this monument of interconnected balls is representing life as a magnificent thing, the linked data. And I'm going to talk to you about linked data. But what I didn't say is that the word that I didn't describe is open because actually the image of the Atomium is not open. When you go to the website of the Atomium, the first or the second thing you will find is that it is prohibited to use the image of the Atomium unless and then they go into the details. When it is not for profit, except if it is to promote Brussels and I think we are promoting Brussels. Except if you are Google then you are also allowed to use the image. And so except for the later, I'm not Google but all the other applies so I decided I can use the image of the Atomium to start my speech on touristic data. And my takeaway is that like it is in the open in the touristic world it is not enough to make data open. It doesn't stop there. You should put your data on a platform and make them searchable. In an analogy, I would say that Wikipedia, which you were also demonstrating would not be one percent of its current size, growth and level and expertise if it would have been just put as data files on an open data portal. The things we are doing with open data are doing too much so it is not enough to put them on an open data portal. You should use them and you should make them searchable on a platform. And I will illustrate that with a journey through the touristic data world. And what you, there is a lot of, you can say a lot about the touristic data but most of the touristic data are open. And it's evident because the more data, the more information the more noise there is about your attraction, the better it is for your visitors and the more visitors you have. So the data are open. Let's have a look at the landscape. How do these data of the touristic sector originate? And very important players are the provinces. In Belgium you have provinces and these are those of Flanders and in Wallonia you have the four I think. And they play an important role in aggregating the touristic information that comes from the attractions and points of interest in Flanders. But it's not only through the provinces that it comes it is also straight to Tourism of Flanders which is an agency at the Flemish government level that also aggregates part of the data. Namely there is the data about accommodation it's legally required that they are aggregated at the Flemish government level and then they go from the Flemish government back to the provinces and back to the users that we see. When I spoke about the fact that the data are aggregated by the provinces we are looking also a bit at the geographical stratification and it's a bit an irony because touristic data don't stop at borders if you are interested in World War I the touristic information is not only in Flanders it's also in France and in other parts of Belgium. So the silence of a geographical segmentation is not the smartest thing you can do if you want to have your data used. Again, later you will see if they are linked the borders are crossed of course. We have also a sectoral segmentation and we have a segmentation of the work that is done on touristic data in function of the audience that is targeted. For example the foreign countries so the promotion of Belgium tourist activities in abroad is another agent than the ones that do the promotion inside Flanders. But also these provinces work and they aggregate data and they make all their own websites if you see and all work they do about aggregation is mostly in function of these websites and that's not wrong but what is wrong is that if the data processing is done in function of the publication of the website and the open data publishing is done afterwards then you are in the wrong street. The right way is to make your data open and then have the publication on a website as a resulting effect of your making the data open. Let's have a look deeper in and what I'm saying now is based on RFPs we have handled with 10Fours in the last year and we see a number of big work processes at the level of the provinces or at the level of the Flemish government and that is they aggregate the data then they create the data so they improve the data, they review them they have been consistent and they publish. And some agencies have also an important topic about sharing data because there are multiple persons working together and if you have a point of interest and you have an image of it you want also to share to your colleagues the same image and you don't want to copy that so the fact that the data should be linked is also included in the sharing. What we see is this process is they intend to build solid and consistent data but they are always managed in silence. The next approach is the one of the data architecture and then it is about how is the data modeled and there is in Flanders the initiative the URL is downstairs there, the tourism open knowledge there is a sematical model made about all the data that go around in the touristic sector and this sematical model is quite complete and it has quite some agreement and it is quite applicable to all the data that is around in the public sector because it is so generic and applicable to everything that we want to describe in the touristic sector. Then we go to the approach of ourselves as users and then I invite you to imagine yourself as a traveller if you travel and in my blog for this conference I had an example of the Museum of Hergé which is close here if you are coming from abroad and you go to the Hergé Museum so you have expressed your interest in comics and in GARF, in Tata then you might also be interested in other information that is related to it for example the comic museum in Brussels but at this moment it is very hard to find these other links you have to hunt for it you have to do your best desk research and your Google skills to find other topics which are related to the Museum of Hergé that link to other points of interest for a tourist and actually that is what we want and so the link data can give it to us but at this moment it is not because they are not linked and there are so no generic patterns and that allow other agreements to help me to find the things that answer to my requests that are contextualized that link and that help me to reuse the data so more or less the picture that applies to our open data governments in the tourist sector is this picture because the data are not reused enough and they are not internally URI referential linked and not reusable to the end we want and what could change this is that all the people who work on tourist data start with the link data on their desktop if they don't say we are going to make a link after everything we have done it's a lost process but they have to do it in the front and so internally already share for example photographs to their own colleagues as link data and then you are having an ecosystem that is linked and I will illustrate maybe you are saying for our future but it's not this is what we have done for West Tour and it's a pipeline tool that helps if you have different sources and all data sources in different formats to have a mainstream desktop and dashboard to convert it to link data and once they are linked data you can plot them and you can have these artifacts these resulting visualizations because they are linked and you can map them on a map and you can use them in algorithms to find a course and a route but also you can make applications on it and before lunch there was the presentation of colleagues of mine who showed the framework of Musemtich and this is actually in-tempo applications that have been made with Musemtich and what's behind this application is a link database all data are linked all data are referenced by a URI but to the end user who is using it you don't see URIs even it looks like a classic work process application where you have controls to do filters to select for example I have things to do and you make a filter and then you can start working on it there are items that you can use to see which items you have still to do and which are the status on them they are reviewed by your colleagues or not reviewed and so the whole application doesn't look like a linked open data set it looks like a normal application and then applied to autistic data we could come up with this all these data that you see are URIs have a URI or URI are in a linked database but to the end user who is the staff at the provincial level or at the Flemish level they treat the data as data but they are shared and so you have here the different topics the different information entities the objects that the touristic information is about and so we are coming close to my head and again what is my message is that it's not enough to have open data they should be open useable but you need an open platform to make these data alive Any questions? So we are back on track? Yes The different provinces use the same ontology for describing their events At this moment not every province has its own team but they have workshops and they agreed on a semantic model and it is now a matter to make it at a Flemish level or even at a Belgian level to make it accepted and agreed there are steps towards it but what I wanted to say is that even if there is no full proof agreement at this moment the semantic model more or less captures everything there are not so many loose ends that I know of things that are not possible that you cannot put in the semantic model it is quite generic Is it based on examples that exist elsewhere in Europe or is it created from scratch too? Which the semantic model? It is there was an initiative of people of the Flemish government I think and of an Hogue school it was a research project and they asked people who are working in the traffic sector to come together and have workshops and then it is the classic process of getting the knowledge out to the people and then have some engineers to model it and then to go back to the people I say does this match with what you are doing so it is an interactive process with workshops and get them to the semantic model There has been things really restored there So... They looked in principle the structure of mutual relations that is a typical one but there are others like opening hours that are not standard so that is the trying to reuse as much but of course you end up in sometimes what is the purpose of this information model so like do you want to sell a room with it do you want to have a payment and so on as well is it more giving the information towards this availability of the different ones this is the only information about touristic points of interest of accommodation, attractions etc it is information only something else there are some attempts to make an ontological model about booking and reservations but these are much more complex and much more difficult to establish there is an initiative I know from a German university but they are not final yet because it is so complex The nice thing is that this was about the information on topics that could be of interest of a tourist to map his tour to make his itinerary Thank you
