 And for today's topic, as Andre said, we have open minds towards transparent publication fees, and I would like to welcome you all to this webinar today, and we will talk about the processing charges of articles and books and as well as transmission agreements. If you like, as Andre said, please Twitter with your tweet with the hashtag here from OpenAir and from OpenAPC as well, and the recording will be published afterwards, including the presentation. The today's agenda is more fine grud and give you an introduction about APCs, BPCs and transmission agreements. We will take a brief overview about OpenAPC, the passive participation. We linked our work to OpenAir and the European Open Science Cloud and have a conclusion and hopefully a wonderful discussion with you afterwards. And who we are, we are a team from Bielefeld University Library, Christoph Bruschinski is today with me, as well as Julia Bartlewski. Christoph is the lead architect and developer of OpenAPC, of the OpenAPC project and starts back in the history as well. And Julia is the co-lead and I'm really exciting that you are both with me today. But a team is nothing without a co-founder, Dick Peeper, could not be today with us, is currently also the project coordinator and Jochen Scheerwagen as an open science advisor. We have Sabir Schaaf from OpenAir Nexus and his future team with us. And my name is Andreas Czerniak and I'm the OpenAir Nexus service manager of OpenAPC. First of all, before we start the presentation, I will ask you some questions. And we have prepared some questions for you. First of all, as you shown in the chat mostly, but I would like to know where you come from. So which continent are you attending currently this meeting, our session today? And I will share with you here the leads, the question and I see most of you comes currently from Europe, of course we are Europe based, but we have also from Asia, America and Africa. That's very good. So I think we can see most have selected, okay, thank you, I will share the results with you. So as you see Europe, of course, but also from Asia and America, that's welcome also to you, explicitly and Africa, thanks for this. And if you like, you could also share your location in the chat. So our next question is regarding your department and in which department you are currently active or act with comes from library or you are a researcher and working in science, you are more than in the organization administration, from consortium, from funder or from other that we don't have here currently. So please share with us your, so I'm waiting for some seconds, I'm not sure if the police is visible to the participants. Oh, excuse me, we are receiving some feedback in the shot that is not visible. As far as I can see it's closed now. I don't know why. Is it now visible? Oh, yes. Okay. That's great. Thank you. Thank you for the hint. Thanks a lot. So more seconds here and share results with you. Hopefully you could, you can see the results. So from the libraries from the science projects and also organization administration and consortia. Thank you. And hopefully the last question before we start is to have you already dealing with article or book processing charges in your position. And now I can see there come some votes in and so many of you has already voted here and I will give two more seconds, close this pool and come to our back to our presentation. So, so thank you everyone for voting. As you can see, hopefully most of you comes from our librarians. Some scientists here, something had nothing to do anything with article processing and book processing charges and some is from financial accounts as well. Thank you for your efforts to provide your so. And with this, I come back to the presentation and would like to give the digital floor of introduction part to you. Thank you very much. Yes. Thank you for the introduction. Yes, I hope you can hear me and a warm welcome from me as well. I'm really delighted to see so many people taking part in today's webinar. So the poll just showed that most of you have already been in touch with APCs, BPCs in some form, but not everyone has yet. So we'll start with a little background so that we are all on the same page basically. So next, yeah, thank you. So first of all, let's have a look at APCs. What are they and why are they important? So APC stands for article processing charge. It describes a one-time fee which has to be paid to a publisher to have an article published open access in the scientific journal. It can either be mandatory for fully open access journals or optional for hybrid journals. And the charge of APCs has become very common for open access publications and are paid by academic institutions, funders, authors or libraries depending on its context. So basically we are in a transition process in which scientific publishing is shifting to open access. So payments to publishers are transforming from subscription fees to APC-based models and also to transformative agreements, which I will talk about in a minute. So APCs allow transparent reporting and cost monitoring for publications in open access journals. In addition, one can say that many funders now only support publications in full open access journals, as stated, for example, here in the Horizon Europe Agreement. So similar to APCs for open access books, we have the so-called VPCs, the book processing charges. And these are also one-time fees that are paid to publishers to publish a book as open access right from the start. So there's, as we noticed, an increasing focus on supporting open access books as it allows especially authors like from the humanities and social science to publish open access. In this area, it seemed the focus of publications tends to be on monographs rather than journal articles compared to, let's say, the natural science. So the VPC market is developing, which is quite notable, but enabling cost transparency and reporting is still at the beginning compared to APCs. Next slide, we have transformative agreements. And transformative agreements have also a significant impact on the open access transformation in the existing subscription models of journal access are linked with open access publishing options. So basically, these agreements aim to transfer subscription-based journals to open access and spending for subscriptions into open access publishing. So also known as published and read agreements, transformative agreements enable reading access to journals and at the same time regulate open access publishing in these journals. So basically, one can say they transform a large numbers of articles in hybrid journals into open access articles. The average cost per article are hard to calculate for these kinds of publications, but Christoph will show you more details later on. And I think that's that will do for a little overview. So next question is, why is transparency of these costs useful? On a larger scale, one can argue that transparency of publication costs contributes to the open access transformation in general as it enables a comprehensible cost allocation. So monitoring and steering of the open access transition requires solid data on payments. Out and transparent data enables cost comparisons between publishers which may counteract publisher-driven price increases. Moreover, one can say it provides an overview of payments from scientific institutions to publishers in general. On a smaller scale, the next slide, making costs on open access publishing transparent has benefits for single institutions, consortia, or funders. For institutions, it enables cost comparisons with other institutions. So APC amounts can be negotiable by institutions and information on what others have paid is very helpful. So you get an overview of how the costs are distributed across the different publishers and to know what has been paid is of course essential for budget administration as well as when applying for funding. Also for consortia, cost transparency is useful as it helps to improve their position against publishers when negotiating conditions. And for funders, transparency is important as well regarding monitoring aspects. So basically which amount was paid for which article to which publisher. So and in the next step, I want to talk a little bit about open APC in general. I think some of you might have already heard of our project or are familiar with it. So open APC is an open data project which was established at Bielefeld University library back in 2014. We collect and disseminate data sets on fees paid for open access publishing and then open database license. What we do is basically we aggregate cost data on open access publishing. We aggregate APCs, we aggregate since 2016 data and transformative agreements and since 2020, we also started on aggregating BPCs. So for these three different types, open APC operates three different data sets. What are our aims in open APC? Our aims in general are to establish cost transparency and also comparability because if you want to make policy or make decisions within this open access transition framework, you need good data and numbers. An important step to achieve this is by enabling transparent and reproducible reporting for institutions and funders. Christoph will explain the reporting to open APC in more detail in a minute. Open APC also wants to help to track development of cost over time. Next slide please. Here, this chart shows the evolution of our APC data set over time with some major events being marked separately. But the important thing you can see here very well is that the number of records has increased continuously over the years. The next slide presents some current facts and numbers in more detail. I can show them all. We always like to present them at occasions like this because, you know, they always go up. So our APC data set is the largest one. It consists of over 178,000 articles, which are provided by 393 institutions. And if you go ahead and sum up all the APCs and the data sets, you get to a total sum of over 345 million euros. The average APC, as you can see in our data set, is 1,930 euros. So there's a lot of money in open access publishing. The BPC data set is somewhat different in terms of numbers. Here, we have received data on 1,577 books from 34 institutions with an aggregated sum of over 10 million euros and an average BPC of over 6,000 euros. So for the webinar, I looked at the history of our data submissions and exactly one year ago, only 18 institutions had actually submitted data on monographs to us. So we can see from this that the topic of open access books is also becoming more and more present in our context. So finally, a short overview of our so-called TA data set, which provides information on public publications within transformative agreements. Here, we have data on over 66,000 articles submitted by 327 institutions from 44 agreements, different agreements. So that will do for a little overview. I now hand over to Christoph, who will present to you how to contribute to Open APC. Yeah, thank you very much, Julia, for the nice introduction. I want to talk a bit about the inner workings of Open APC about our data workflows and data routines. But I also want to talk a bit about our data submission process because in the initial polls, we saw that a lot of you are working as librarians and also had already been working with APCs. So as all of our data is contributed on a voluntarily basis by institutions, as we saw we are at almost 400 participating institutions at the moment, some of you might be possible candidates for submitting data to Open APC. And I want to talk a bit about the submission process. And I think you will see that it is really fairly easy because that's one of our goals to make the data submission process as easy as possible. So first, I want to highlight our data handout. Andreas, I don't know if you can click the link possibly or is it not possible? Let's see. One of modern data processing. This link leads to our GitHub repository. And this data submission handout, basically, it sums everything up. You need to know when you are contributing data to Open APC. I won't go into too much detail here. I think you can read it for yourself later. So we can go back to the slides, please. Yeah, thank you. In the handout, you will find what is very important, the definition of costs, because Open APC aggregates costs on open access publishing. And when we say we aggregate costs, the definition of this term is, of course, very important. For example, there are questions like if you pay an APC a Texas value at a Texas, for example, are they included into the cost lump sum? Or are things like submission fees or things like page charges, are they a part of an APC spoiler? They are not. But this is all important to know, because if you want to contribute data to us, you have to know what kind of data you have to contribute. So you need a definition of costs, and that's all included in the handout. Second thing is, how do you send the data to us? Well, the most common way is to just send us an email to a project address. I don't know if it's included into the slides. It's open APC at Winnie Meadow's Bielefeld DE. Sending an email is the most common way. I think over 99% of our participants just send us an email, basically every year, which contains a CSV or Excel sheet with the APC expenditures for the recent year. What you can also do is if you are a bit more technically savvy, you can go to GitHub. And if you have a GitHub account, you can make a pull request there. So you can integrate your files directly into our repository. That's a bit more of an advanced way, but that's not really necessary. Sending an email is the preferred way, and it's totally OK. And if you are a very advanced institution, I'm just mentioning this for the sake of completeness. You can do something like exposing your data from your institutional repository. Some institutions do that. They do something like we can see in this little graphic below. They basically integrate the data from their university financial accounting systems directly into their institutional repositories. So we have a repository with all this bibliographic data, like the title of the journal and the publisher and the article title and an ICSN, for example. And there's also a field for costs for this article, open access costs. So there's a field for integrating the APC. And then we from open APC can come to your repository, do our harvesting via the OAPMH protocol, and we can directly fetch those articles from you. But that's very advanced and only, I think, four or five institutions are doing this. So just for the sake of completeness, that's not really necessary. Just send us an email. So next slide, please. Who can submit data to us? Well, the easiest answer is everyone. Single institutions like universities or research institutes can submit to us. Also, larger bodies like national aggregators, library consortia, funders, for example, with all this kind of different institutions submitting data to open APC. And a bit of a question is always, of course, how to collect the data in the first place. This is basically the most difficult question, perhaps, for you as a librarian, for example, working at the library. If you've paid for article processing charges, how do you link those financial cost data with the bibliographic data of the articles? So this is often the most difficult hurdle to overcome to collect your data. But if you've managed that, then it will be quite easy because, as we can see in the next slide, reporting the data is really easy. We use common format CSV, common separate value files. And it consists of 18 data fields, but only five of these are mandatory when you are reporting your data to us. I think we have a small overview here. As you can see, this is our open APC data schema. And it consists of 18 data fields, but only the first five of those, which are marked in orange here, those are the data fields you have to include into the table you are sending to us. So it's the name of your institution. It's a period value, which is the year, the invoice for the APC was paid in. Then it's, of course, the amount. We are preferring the amount in you, but you can also send us in another currency. We can automatically convert it. Then we have a DOI. That's very important because the DOI is the main identifier we are using to basically bootstrap our enrichment process. We will have a look at that in a minute. And we also need information on the hybrid status of the journal the article was published in. So if it was a gold OR journal or a hybrid journal. And all the remaining fields we can see here, you do not have to report to us because we are enriching them with our automated enrichment routines. For example, those blue fields we can see here, like the publisher or the journal title, we import from Crossref. Then we have, for example, the ISISNL, the linking ISISN, which we get from the ISISN organization. We have PubMedID and PubMedCentralID, which we get from your PubMedCentral. And we also get data from the DOIJ if the journal is included there. So next slide, please. This is a bit of a wild picture. This shows how the enrichment workflow takes place. I think you don't have to understand it in all detail. What we can see at the top is you can't really see it's a bit small. But that's basically the five fields which we are reporting to us when you are sending us data. And what we do is that we take the DOI. That's why the DOI is so important. And we first go to Crossref to query if this article is listed in Crossref. And if that's the case, then we go and we see that it's a journal article. It's also in kind of information we obtain from Crossref. Then we get to the left part of the workflow. And we basically obtain all the data automatically. As you can see, we go then to your PubMedCentral and get the PubMedCentralIDs. Then we get to DOIJ. Then we get to ISISN organization and finally to Web of Science. And then we end up on the lower left, which a fully enriched article and all the metadata is in there. And you don't really have to care about it. And the rest, the right part of the graphic shows what happens when you submit a BPC to us. And that is a little bit different because for books, there isn't such an established infrastructure to obtain metadata. It's basically only the DOIB, the directory of Open Access books. But in the end, it's basically the same. Also for books, the metadata is automatically enriched. So next slide, please. What happens when you report your data to us? What are the benefits? What we do is we do a lot of data analysis and data dissemination. For example, we can see here, these are plots and tables which are integrated in our data reports. And in our blog post, we create a blog post for every data submission. So you will get some nice graphics for your submitted data there. And next slide, please. What Open ABC is perhaps most famous for are our 3MAP graphics. So we operate a service where we generate these nice little rectangle graphics. They are called 3MAPs. And what you can do here is that you can basically click into the data so you can explore the data on different levels and from different perspectives. So that's very nice for gaining certain insights on the data collection, which we already saw is quite large at the moment. You can find these graphics at that URL on the upper right, 3MAPs.openabc.net. And perhaps, Andreas, you can click the link, which we see there. Yeah, thank you. That's the 3MAP site. And as you can see, you can hover over the 3MAP. And yeah, thank you. For example, you can click on one of those rectangles. And then you get down basically one level. So what Andreas did here, he clicked on one of our participants. I think it's the FWF. That's the Austrian science funder. And what you can see here is all the journals. That's the next level, the journal level. The FWF paid APCs in or published articles which were paid for. So perhaps you can go back to the main URL. And click on the open APC link in the upper. Yeah, that one. Thank you. Because what we can see here, that's interesting. We have this little world map there. And that's basically one of the reasons why we are doing this webinar. Because as you can see, most of our participants at the moment are coming from Europe. I think if you can hover over it again, 382 institutions from Europe, from basically almost 400. So we have really a great majority of European participants. And we have some from North America. If you can hover over there, I think it's seven from the US and from Canada. But as you can see, there are still many, many white spaces on the map. For example, we are at the moment not one participant from South and Middle America. We have, I think, only one participant from Africa. We have no one from South Asia. For example, there's no one from India, no one from China. And of course, these are white spots we really want to fill. Because at the moment, it's really a very European project. But of course, APCs and BPCs, they are basically paid everywhere on the world. And we would be really interested in data from other regions. For example, we really want to know what's the status of open access publishing and payments for it in Africa and South America. Are the prices on the same level? Or for example, do they get a discount from the publishers? These are things which are not known at the moment. And we only can fill these gaps if some institutions from those regions of the world do submit data to us. So that's really something we are striving for at the moment. I think we can go back to the slides. Thank you. So that's the three maps. And next slide, please. So that's basically the data schema for the other data set for our BPC data set, which contains data on book processing charges. It's somewhat similar to the journal article set, the open APC data set. But it's the same principle. You only have to report five data fields to us in your tables. And the other ones are basically enriched by us by querying those metadata services. What you have to submit is, again, the institution name, period, and the euro, which is a BPC, not an APC in this case, also a DOI. And then we have this field. This is special for open access books. It's the backlist or a field. It basically tells us if this book in question was already open access from the beginning when it was published, or if it became open access later, because someone basically freed it by paying in the BPC retroactively. It's basically, in most cases, it will be the case that the book is open access from the beginning because BPC is paid right after publication. But there may be some case where it's not. And then for the sake of completeness, on the next slide, we have the TA data set, Julia already mentioned. I won't show it here because that's not really that relevant because the TA data on transformative agreements, that's data which is usually not reported directly by institutions because the cost data for TAs is quite complicated because there's so many different models on payment and costs within the field of transformative agreements. So TA data is not really reported by single institutions. We get this kind of data usually only by funders and national consortia, for example. So I think that was my part on the inner workings and how to contribute to it. I think we all saw that it's really not that difficult. Basically, all you have to do is to compile a table with these five mandatory metadata fields and then basically send it to us and we will handle all the process. And I really want to encourage you if there is some possibility for you to get your hands on some payment data, be it BPCs or APCs in your institution, we would be really happy if you could provide us with such a data set. And it really doesn't have to be that large. I think we have participants which have only, I think contributed a data set of only five or six articles and that's perfectly fine because every bit helps the project. All right, then I think Andreas will have some more remarks on the European Open Science Cloud and how OpenAPC and its data fit into that. Thank you very much. Thank you, Christoph. Yes, of course. So, and I will take a look, brief look to the Open AIR services which are integrating OpenAPC, the OpenAPC data set directly from the GitHub that Christoph has shown. So the Open AIR research graph harvesting the OpenAPC data set which covers APCs and BPCs and integrate these in the Open AIR research graph. On the bottom, you can see the Open AIR research graph on the right side, you see the literature, the publications, the data sets, the software and other research products and so on. And in Open AIR, this is called the research product. A research product comes from a data source which you can find on the top left middle and has authors identified by ORCID. Mostly comes from projects, is linked to projects and funders and funding streams and so on. And into this graph, the APC and the BPC links on the one hand to the publication and on the other hand to the organization that provides the processing charges to the OpenAPC project. And then for this, the Open AIR research graph integrates and link these amounts together and one of the services that I use these APCs currently is the Open AIR service called MONITOR which are showing the APCs currently over the time, what is published firstly and latest one and as well as give you an overview about the top journal. It's similar to the tree map that Microsoft has shown before on the one hand for total APCs but also for the average ones. These are short overview about the APCs in Open AIR currently, the Open AIR MONITOR based on the Open AIR research graph. And these Open AIR research graph is also one of the core component for the European Open Science Cloud. And here we would like to have Open APC as well. So the European Open Science Cloud is a trustworthy and federated environment for an interdisciplinary scientific collaboration in a fair manner of course. So and here we would like to achieve some cost estimation for open access publishing as well as the estimation of cost for public publishing of the research results for researchers. It is a short lookout, short outlook, is the Open Science Observatory which is an Open AIR joint service which is also based on the Open AIR research graph and will also present the BPCs and APCs to each country as you can see here for the publications. And with this I would like to conclude the presentations on base also on the time that we have. So Open APC is, I will say fully compliant with fair principles is open, it's community driven and fully transparent, it is on GitHub, you can search and evaluate the raw and enriched data as Christoph has shown before, all available on GitHub, you can take a look to the visualizations and as well if you find in the Open APC blog the reports for your institution or for other institutions and can make compare these data sets. APCs and BPCs as Julia and Christoph said becomes more and more available for everyone and especially for the institutions and funders and as Christoph also said, every data set is very welcome to the project to have a better view on the APCs and BPCs on the global level. For this, I would like to thank you and give you here the contact email as Christoph said, OpenAPC at oneybilefeld.de, if you have any questions, we come now to our Q&A session. So in the last 10 minutes, I don't see the chat currently but I think I will open the chat as well and then... We have some questions in the Q&A section. The questions that we have in the chat, I added them in the Q&A area so you can manage all the questions in the Q&A area to simplify, to reply to other questions. That's great. Thank you, André. Let me find here the Q&A session on my Zoom window. Are you available to see the Q&A? No, I see only the chat currently but I will stop the sharing and... Okay. Yes, I could now see the Q&A. Okay, go ahead. Perhaps we can then directly attend to the questions in the chat because I think there are many questions which are related to my part especially. If you're okay with that, I can just go ahead and answer them. Yes, so the Q&A could also answer the question as itself. So you can then answer live or type your answer in the Q&A part. The Q&A part, please be aware that we are recording the session and if you ask your question via microphone or via the Q&A, you can do it also anonymously. So how could we start? I'm sorry, Andrés. Anna, we have a participant who has raised her hand so I don't know if you want to let her speak first. Anna? Please, Anna. Maybe my mistake. So, but Kristoff, if you see some of the Q&A, they are... I'm only seeing the questions which were posted in the chat, but I do not see anything on the... Yeah, I don't see anything. Are we supposed to see something on the shared screen by Andrés or...? In the Q&A, please. You need to go to the option below in the Zoom channel in which you have the chat icon and you have on the right the Q&A option to see all the questions. If not, we can raise the questions and... So, yes, I would like to raise question and combine this one. So, one question from Yu Zhang. Print.issn are now obsolete regarding OpenAPC. That's one question. And the other question is mandatory data. What if the journal does not use DOI pits? Okay, I didn't get the first one. Can you repeat it, please? The first one was Print.issn are now obsolete regarding OpenAPC. You're right that Print.issn become less important, of course, because while we are talking about open access, so open access, of course, only applies to electronic publishing. We still record Print.issn in the OpenAPC dataset, but that's mainly only because they are listed in Crossref. So, what we do is we basically import all the Issn, which are listed in Crossref. And since Crossref also does hold data on Print.issn, we also integrate that into our dataset. But while basically you are correct, the Print.issn are not really important. The electronic Issn, they are much more relevant to us. Thank you, Gustav. Some interesting questions from Anonymous. We don't have any centralized managed APC fund in our university. APCs are re-embrashed to individual researchers from their research grant money based on the APC payment receipts. Are the institutions in a similar positions or similar situations? How do they monitor their APC expenditures at the institution level? Yeah, that's a really, really good question. I think that's really the most or the really biggest obstacle on the whole process of reporting APCs to us. Because at the beginning of the process, these APCs have to be collected somewhere. And how this is supposed to happen in an institution like university with different departments and different financial accounting system and whatever, that's really, really difficult. And to be honest, the most data which reaches us originates from centralized institutions like university or a funding or a funds from universities which are often located at libraries. Because when they do funding, what they also do is they do the bookkeeping. So they have those Excel spreadsheets floating around somewhere and can just send them to us. But when it comes to a university-wide monitoring of APCs, that's really an unsolved problem. I don't think that anyone has come up with a good solution to that yet. Thank you, Christoph. Then we have a question regarding the non-euro APCs amount. When you convert non-euro APCs to euro, what exchange rate do you use for it? That depends on the timeframe you can support us with. We make use of an API by the European Central Bank where we can obtain historical exchange rates. So we saw this field, this mandatory field period in our data schema. This is where you put the date of payment in. And if the state of payment is just here, then we can only use the annual average rate for that year. But you can also put in a more detailed date. For example, you can also include the month or even the day. And if you can pinpoint the specific day of payment, then we can do a very precise conversion because we can use this ECB API to get the daily exchange rate for that specific day. So then we have a very precise conversion. If you can only provide us with a year, then we have to do with average rate. And then, of course, the calculation gets a bit imprecise. But we are flexible in that regard. Thank you, Christoph. The next question was, mandatory data was a DOI as persistent identifier. What is if the journal does not use DOIs or persistent identifier? Another good question. Fortunately, that happens less and less. I think journals which are not minting DOIs get really rare these days. But it happens from time to time. And in that case, you would have to support us with a substituting data set. Instead of a DOI, you would tell us the publisher, the journal title, the Isis N. And that's really important. You would also have to tell us an URL where you can basically, which points to the full text of the article. Because one important property of the DOI is, of course, that you can find or identify the article, which this APC was paid for. And if there is some DOI, then we have to rely on some other means to detect or identify the article. In that case, you would have to provide us with an URL, preferably to the journal landing page or perhaps to an institutional repository where this article is stored. So it's not the most comfortable process, but it's possible. Thank you, Christoph. I think there's a comment from Sophie in France, the Copperen Consortium, centralized information from institutions and declares all data once a year, I think, for OpenAPC. Yes, absolutely. And that is really a very nice workflow because we are in contact with the Copperen Consortium. And they are also OpenAPC participants. And they are sending us all this aggregated and cleaned up data in, I think, weekly intervals, which is very, very easy for us because we get all this data from France, from lots of universities. I think we have about 60 or 70 participants from France. And that's very easy for us because this data is already aggregated beforehand by Copperen and then sent to us. So we don't have to communicate with each French institution on ourselves. It's done for us. And that's a really good example of how national aggregators can basically pay a role of making, so to say, a link to OpenAPC. And this is really, really good for us. And yeah, good that it works in France, but I think most countries are not that centralized. And yeah, there is no national or central aggregator in most other countries, which is a shame. Yes. It depends on the time. We are six minutes over, but I will give a question from SESTA. Is it necessary to sign an understanding agreement before a consortium can be part of OpenAPC? No, absolutely not. That's basically one of our selling points, so to say. And there is nowhere tape involved. You don't have to sign anything. You don't have to sign a contract or do some formal registration or whatever. You just send us your data and by sending this data, you are implicitly agreeing to putting the data under an open database license because that's what we are operating on. And that's basically it. You send us your data, we integrate it, we process it, and then you're part of OpenAPC. So no processes, no red tape involved. Still, and there are some questions regarding the transformation agreements. This is very interesting. One asks for ISAC initiative have abandoned transformation agreements, data submitted by everyone globally. Any plans to cooperate with them? We did, actually, because I think Julia mentioned the Intucked Initiative, which was started in 2015. And that actually was a joint project by OpenAPC and ISAC. So yes, we are in contact with them and we are working together on some of these points. Great. So let us... There are so many more questions open. I think we can go through it afterwards and give you some feedback on this. And we should finish this webinar for today. Let me share my screen for the last slides. So as a reference, you can see here all the links in the reference slide. And give me the chance to ask you some last questions in a poll. So the question is, can you imagine delivering your article book processing charges to OpenAPC? Hopefully you see the poll now. Yes, okay. And there are some options with yes, no APC and BPC and yes, no BPCs, not APCs and so on. So please make a single choice here for you. And I will share this result in a second, I assume. Okay, I think it seems to be stabilized. One, two, three. I'm ending the poll and share the results with you. Currently, someone has no intent to deliver OpenAPC to the OpenAPC project currently, but many of you are seeing the next six or nine months or has an roadmap. Oh, that's great to see. Thank you very much. And my last question is regarding to reuse OpenAPC and reuse the OpenAPC service. I would like to ask you, could you imagine to use OpenAPC data comes from the OpenAir Research Graph or from the OpenAir, from the OpenAPC APIs directly or from the GitHub in your process on your website or use as a forecast for your institution, for a budget. And I see many of you are already vote for this. So in this case, it's not really explainable, but you can embed some information from the OpenAPC website directly in your web page, but you can also have direct look and analyzing the GitHub data set directly. So in this case, thank you very much. I ended the poll in 3, 2, 1. And share the results. Hopefully you can see that most of you are using, you could imagine that you use OpenAPC for the budget calculation, also for the own analysis from the GitHub or APIs. And, wow, some say about to embed the tree maps directly in the institutional website. Great. In this case, thank you very much for providing these insights from you. And I would like to thank you, André and Paula for sharing and hosting these webinars for today. I would like to thank you Christoph and Julia. And I would like to thank you for your participation in this webinar. And if you have any questions or feedbacks for us and if some workflows doesn't fit your needs, please contact us via OpenAPC at unibilfeld.de or give us a note via Twitter. Thank you very much. Thank you all and I will give the floor back to André.
