Hello, good morning everyone. I'm Christopher Peters and I'm going to present you Grotto Center. So, first a bit about me. I'm from Belgium. I'm mostly working as a trainer and consultant in open source and DevOps. And in my free time, I'm spending quite
00:24
a lot of time doing outdoor adventure stuff, such as, for example, I go into caves. By the way, for the people who like to enjoy the pictures of my slides, this is the only picture that I didn't take. So, it's a bit difficult to take it when you're posing for it. So, first a bit about caving or spherology. So, what does it
00:43
actually mean? It's mostly a scientific study where we are going into caves or outdoors and explore cast phenomena or caves in particular. If we got, if we are going into caves to study what is happening over there, there are
01:00
different sciences that are involved. There is geology, there is biology, there is also a lot of physics and chemistry involved. But in general, to get to the place that we want to study, we need to go and pass certain obstacles. We have to crawl through some small passages, we have to descend
01:20
into pits and for that we need a certain physical activity to get there. So, there are some people who did this for science to actually research things that are happening down there. There are other people who just like to do the physical activity and so it's also a bit of a sports. For the people who are a bit familiar with other terminologies, in English it's also known as caving,
01:45
potholing, spelunking. So, there are different words for it. But in general, the idea is we go into caves. Now, if we go into caves, of course, there are a few things that we have to keep in mind. And one of the things that I would like to present to you today is a problem that we often have to deal with.
02:03
So, when we go into caves, on this picture you can see a person who is descending into a pit on a rope and this is something you don't do just like, okay, you know, it's 10 o'clock, let's go and see what's in this hole. We actually do some preparations. For that, we are using a
02:22
lot of information that we are consulting to make sure that we have the adequate equipment with us. We have also made sure that we are using the right tools, that we are also making sure that we're not going in the wrong moments, because sometimes also weather conditions can make a very bad influence
02:41
on the conditions in a cave. Here you see an example of a survey. We have quite a lot of surveys that provide us with information on how the cave looks like if it has already been explored. And we can use these surveys to also make sure that we have all the rigging material with us, that we make sure that
03:02
we know where we are going, what we are going to do and what kind of dangers that could be involved in this trip. For this, we have the surveys, they provide us with this information. There's also sometimes a description that is added to the survey which provides us more
03:22
information of, for example, how to get to the entrance, maybe some particularities, special things we would like to see or special things we would like to avoid, and sometimes also separately we have rigging information. That's not always the case, but depending on how well a cave has been
03:41
researched and explored, these documents are available. On this survey, there is also, over here you can see that there is an indication which actually also tells that this is a pit of 20 meters, and so sometimes also this information is only available on the survey. Except for that, we also have
04:02
other information which is not very necessary to just facilitate the trip itself, but which can give us some more background. For example, scientific research that has been performed, some information about the region that could be geologically, that could be biologically, that could also be, for
04:22
example, information about how rivers are flowing above and underground. There's also other kind of research that can have been performed that isn't necessarily limited to this specific cave we're going to visit, but that could be more broad and give more information about also the
04:41
region or maybe a particular kind of cave. And other documentation, like for example, when they made this survey, they also took measurements. This survey has been made probably with compass and just measuring tape, and thus they might have taken notes of that, they might have also saved them somewhere.
05:01
These days we're also using more modern technologies such as radar and 3D scanners, and also those data points that can be saved, and they can also be archived. All this kind of information is available at a certain location most of the time. It is the person who has actually, who has
05:21
generated this information, who owns this information. But if we want to share this, we are very much scattered around the world and there is not such a thing as a central database. That is the actual problem we have to deal with. So if you look at how we are going to share this information these days, a lot
05:42
of this happens by email or by websites or blogs, sometimes also some file transfer services, but in general all the information is at one specific organization, one specific person or group of persons, and you have to know where you have to go to if you want to actually access the information.
06:03
There are some countries who do have their central databases, but this is not something which is also standardized or generalized. If we then have the information about the cave, like for example the survey, how also are we going to link this with scientific research that has been performed around this cave? That is also one of the problems we have to
06:24
deal with. If we are contacting someone because we want to visit the cave, very often we get a survey or we get a description or we get a combination of both, but we don't get all the information that is available. Also because very often this information is not centralized in one sort of group of
06:41
people. Some people have one part of the information, other people have another part of the information. And then when I contact someone to obtain this information and if I have been using it for a while and then afterwards an update has been provided on this information, how am I going to make sure that I'm also getting this update? Because also in this world science is
07:05
still moving on, we are still exploring new places underground, we're still finding new places, new caves and so all these kinds of information need to be shared as well because the survey that I was showing before is a very old one. There are already several newer versions
07:23
of that available right now and so if I get this survey one day and a newer version is made the other day, how am I going to make sure that I also get this if the person who sent me the first one is forgetting to also send me updates? For that there is a solution and this solution is Grotto Center. So
07:43
what is Grotto Center? It is a sort of wiki database which is made for caves and also mostly made by caves. So there are a few people in France, they have been starting developing a database which they use to store all the information and it is made public available so that everyone can use it. It
08:05
is supported by the European Caving Federation and it is also supported by the International Caving Federation who also officially hosts some parts of this. The idea is to have a global source of all kinds of information about
08:22
caves and cast phenomena and to have it with an open access so that everyone can access this information. Also with the idea to use standards so that all the information is saved in the same way and it is very easy for everyone to also add information and also query this. And because we are using standards we are also making it very easy to make it accessible by
08:45
machines as well so that you can query this using APIs. How are we going to then use these kind of standards to make sure that everyone can access this information? For this we made a standard which is called cast link and
09:03
which enables us to link all the different documents to caves. For this we didn't really try to reinvent the wheel, we just extended a tool which is from the W3C linked data and semantic web and this enables us to store the
09:21
information in such a way that it's very easy to access also using machine readable sort of ways such as APIs. And then you have Grotto Center itself. So here you see the front page of the website where you have on the site menu bar which you can easily use to browse information. If we then go you
09:44
can see that there's a quick search and advanced search. I'm going to skip those for a moment. I'm going to skip to the map and then here you see a screenshot of a part of Belgium where you can also see all the hexagons which are indicating where are caves or cluster of caves. So these are just sort
10:02
of caves bundled together. If you further zoom in then you can actually see over here you can see that there are also indicator switch points where you can find certain caves. And then you also have over there the pop-up which appears when you click on one of those points which provides us with some information like for example here which cave has been found at that
10:23
location and then also a link to the datasheet of this cave. So this is the datasheet of that exact cave. You can see then where it is on the map. You can get some basic information such as for example the exact GPS coordinates, some information about how deep and how long the cave is when it's been
10:40
discovered. And then if you browse down here you can also find some information about for example the location. If you go down a bit more in the description you can also find documents such as the cave survey. Not all this information is of course very extended. It depends very much on the people who add this information. So this is one that has been created
11:02
automatically using an import which is done during migration of Grotto Center from version 2 to version 3. But most of this information is being provided by users. It's just like Wikipedia. If I don't write a web page, a Wikipedia
11:22
page about Grotto Center then there is no Wikipedia page available about Grotto Center. So this is information that can be shared by everyone. On the top there's also a login which enables you to add to your information yourself. How are we making this possible? We are using different
11:40
technologies. The complete infrastructure is running on AWS and Microsoft Azure and we're using Docker to also host our application. For the rest we're using quite a lot of JavaScript so there is a note involved, there is Sales.js React. We are also using a GitHub to host our code so you
12:02
can also browse the code freely because this is of course it's an open source project so the GitHub project is freely available. You can check out the code over there. For the rest you can also get in touch using our Slack channel. There is a wiki which explains how you can use this tool if
12:22
you want to add information and then for the rest a few other links. For example here you have the Wiki Caves Foundation. The Wiki Caves Foundation is the foundation which is responsible for the project. So Grotto Center is being officially organized by Wiki Caves. They are also making sure that all the
12:43
funding and all the partners are being addressed. Then a link to what is called the Documentation Center of the International Caving Federation where you can find all the scientific documents. They have been imported into Grotto
13:01
Center so these days if you are browsing information about specific caves then you can also find all the scientific bulletins linked to specific caves. And last link is one to the Cast Link project page where you can find more information as well as the current standard. So we are building
13:24
this mostly with people who are doing spellology and who are by accident also IT people. But we are also very grateful that we from time to time get some interns from different schools that want to build on specific parts of
13:42
our project to make it better and to also add more functionality. And for that we can rely on interns from the Polytech of Montpellier as well as the Epitech from Montpellier and the University of Grenoble. So many thanks to them as well. And now some of our partners. I didn't list all of them
14:03
because then my slide would be very full but there are quite a lot of caving clubs and caving associations, federations who are sponsoring the project and who are making it possible that we can build this and we can host this on an infrastructure that is also made it that makes it possible that
14:24
everyone can access this. So hereby I would like to conclude my presentation. If there are any questions and I'm very eager to to answer them and if you have any questions later you can also reach out to us on our slack or github or project pages. Thank you very much.
