 So, good morning, everyone. Again, many thanks for joining this webinar. This webinar is part of a series of webinars that OpenAir Nexus is organizing. Our goal is to organize a set of webinars focusing all the OpenAir services. Today, the service that this webinar will focus is the OpenAPC. And in the upcoming months, we are expecting to have more webinars targeting the other OpenAir services. So, you are invited also to participate in these upcoming webinars. So, today, our webinar is about the OpenAPC service. And before we start the presentation, just a few housekeeping rules. So, this event will be recorded. By default, the participants' microphones are off, but at the end, we will have some time for questions and answers and you are able to open the microphone and make your questions. If you want to participate, you can use the chat to introduce yourself, to interact with participants and write some questions to the speakers. And you are also able to raise your hand to speak. The presentation and recording will be shared with you by email after this presentation. And you can also share these events in the social media using the OpenAir hashtag or referencing the Twitter channel of OpenAir and OpenAPC. So, making this brief introduction. Today, we'll have Dik Beeper and Andreas Kserniak from Bielefeld University, Germany, that will present the OpenAPC service. So many thanks for accepting our invitation to make this presentation. And I pass the words to you. So, thank you, Andreas. Thank you for the opportunity to give the presentation here about the new OpenAir Nexus service, OpenAPC, today. And also welcome from our side. Let me share my screen. Moment and full screen. Perfect. Thank you. So, in our presentation today, we give a brief overview about the cost transparency of open access publishing. And we'll take a closer look to the European OpenScience Cloud Integration in OpenAir. So, today, I'm with Dik Beeper present the OpenAPC service. Dik Beeper is deputy head of the Bielefeld University Library and one of the co-initiative initiator of the OpenAPC initiative. And we'll make the presentation today. And I'm extremely glad to see Krzysztof Boczynski and Jürgen Schierpark also here with us. Thank you very much. So my name is Andreas Kserniak and I'm the project officer at Bielefeld University for OpenAir Let the task to integrate the OpenAPC into the OpenAir ecosystem. So now I would like to hand over to Dirk and the virtual floor is yours. Yeah, thank you Andreas. Thank you Andre for your kind introduction. Yeah, I will have the first two parts of the presentation. Andreas, can you click for me? Thank you. I will give a short introduction about OpenAPC and we'll talk about how to participate in this project. And then Andreas will take over and speak about the European Science Cloud and OpenAir integration and in the end we will give you a short conclusion and outlook about OpenAPC. Okay, short introduction about OpenAPC can be described as an open data project, which it is from the very beginning. We started in 2014 and we have in general two aims. One aim is to release data sets on fees paid for open access journal articles and monographs. And the first or the second aim is to enable that transparent and reproducible reporting for institutions and funders. And by this we want to create cost transparency on the APC and BPC market. This was I think very new in 2014. And we're still around. We received some funding from the German Research Foundation from the Federal Ministry of Education Research in Germany and we are happy that we can take the next step and have a broader vision in the European context with OpenAPC. Okay. One part of OpenAPC is the acronym APC, what are article processing charges. I think most of you are familiar with this. At the beginning of the 2000s, some open access publishers came to the market like PLOS, BioMod Central, Frontiers and so on. And APCs are more or less a price tag for articles in those kind of journals. And they can be defined as a one-time fee to be able to a publisher to have an article published in a fee based open access journals. Of course, I know that there are a lot of open access journals that don't want to have APCs, but as I said at the beginning they are the main publishers with recent parts of the publication output in universities or other institutions want to have APCs for open access journal articles and they are widely used for publications. I don't know how it is in other countries, but as far as I know, normally APCs are paid either by academic institutions, by funders or by authors themselves or by libraries. And in Germany we had a huge funding program by the German Research Foundation which started already in 2010 and which supported academic libraries or academic institutions in Germany to create organizational structures in order to support the payments of APCs. And as far as I know, in other countries, these kind of programs happen as well. So when these programs or funding started, we figured out that we needed transparent reporting and some cost monitoring for publications and journals. And if you look at more recent funding program projects like for example the Horizon Europe's General Model Grant Agreement. We are now in the phase where the European Commission says that only publication fees and full open access journals for peer reviewed scientific publications are eligible for reimbursement. More strict than the Coalition S or Plan S is delivering they allow funding also for OA articles in hybrid journals, as far as they are within a transformative agreement and it's interesting to see that the European Commission took another step forward, maybe because the Horizon Europe program is running until 2027. But we see that APCs will be with us for the next years I would say. Next slide please. And of course APCs are not the only fees to be paid within open access publishing, there are also so-called book processing charges from my experience and at our university I would say that a lot of scientists, especially from the humanities and social sciences said it's great that you support journal article published in open access journals or in hybrid journals but what about the disciplines which like to publish books and that was one motivation also to think about how we can create a transparent reporting for book processing charges and I will talk about this in a minute. Next slide please. What we also see since I would say 2015 or so when these kind of agreements were maybe called offsetting agreements. We see that with international initiatives like OA 2020 or other initiatives see that transformative agreements become more and more important and what they are trying to do is that they want to transform subscription based journals into OA and also very important they want to transform the spendings for subscriptions into OA publishing and it's very let's say complicated to calculate the cost per article within those kind of transformative agreements because they still incorporate subscription expenditures and on the other hand they are as I said in the beginning very important because they have the potential to transform large numbers of articles in hybrid journals into OA. Maybe you've heard of the German deal project. And I think since 2019 to 2020, we have two big transformative agreements with Wiley and Springer Nature, and in those two or one and a half years, more than 23,000 articles in those hybrid journals were transformed into open access. Of course, we are in a transition and therefore we need to know how much an article is or how much the article costs in those kinds of transformative agreements and that's why we in open APC are also dealing with transformative agreements as well. And I mentioned it before, Plan S still allows reimbursement for articles in hybrid journals with transformative agreements, but the European Commission for rising Europe is now only reimbursing articles within Goad OA journals. Okay, next slide please. This is a short overview how the number of records or the number of articles developed over the years. Next slide please. There you can see how the number of articles grew during the last three years for transformative agreements. And next slide please. Here's a short description how much articles we have currently in our data sets. We think, of course, the APC data set which we originally started in 2014 is by far the biggest one. It was only started last year and in this case, I think we are in the beginning and transformative agreements since 2016. We see also a lot of articles, but only a small part of it has cost data as well and I will talk about this in a minute. Okay, this is only a short overview for the data sets we are currently offering. Okay, next slide please and this is maybe even more important deals with the question how to participate in open APC. And of course we want to convince those people who are not part of open APC to be part of open APC and to be part of the community. When you will get the slides, you can click on the links in this slide. What I want to say in the presentation is that we have kind of handout which describes in detail how to participate and how are the requirements for the data we want to have. We've learned in a lot of talks and a lot of discussions how to define the costs of open X publishing how to deal with discounts for example or how to deal with taxes. And this is described in detail on this website. Then we have in general two ways how to deliver data. One way is to deliver a CSV file, just simple with an email. And this is preferred by most of the data providers for those people who are maybe a little bit more technical and once I can, can create GitHub pull requests and deliver the data with this mechanism into open APC. And, but what we want to achieve during the next year in a new project which is funded by the general research foundation is that we want to harvest those kind of data via where I PMH, and we think that this way has some advantages. So the delivering institutions for open APC, but it also has the potential to strengthen the role of institutional repositories in this environment, because of course every institution who is funding open access articles or is paying for open access articles also wants to disseminate those articles within their institutional repository. So the proposal, I think some years ago how to define a meter data set, which also incorporates cost information for articles, and we have implemented it with some pilots in Germany. So our goal for the next year is that we want to have more data providers within open APC using this mechanism in order to deliver data to open APC. And if you want to get more information about this you can click on the link and see our proposal for the the metadata format and the way how to integrate cost information in your meter data set in your institutional repository. Next slide please. Over the years we see that, of course, single institutions like universities are providing data, but we also have a lot of national aggregators like, for example, the the Austrian Science Fund, or JISC in UK. We have also a national library consortia like, for example, the Borough consortium in France. We have a Swiss consortium is very active in providing data to open APC. We have national international funders are providing data to open APC like for example the Welcome Trust or the Bill and Melinda Gates Foundation. We are happy to to to get as much as data as we can, and no matter if it is a single institution or aggregator. If there are aggregators in certain countries, then of course it will be great that there is a kind of, let's say agreement or communication between an institution and an aggregator in this country. We also learned over the years that the expenditures for a publications are often managed centrally in universities, for example, by by the university libraries, but we've learned that it's often not the case. And it's for those institutions, it's normally very, very hard to to get the information out of the university or the academic institution. And we have seen in many countries, France, for example, but also in Finland that libraries, for example, are trying to or library consortia trying to get the data out of the institutional financial systems. This is very hard work. And we have a lot of respect for those for those institutions who are doing this. And of course, nobody can expect that every data set is complete 100%. Also the libraries and universities normally don't achieve 100% of every expenditures for a publication, but that's not the goal. The goal is to to get, let's say an insight or an overview about how many publications are funded or paid in an academic institutions and to get a feeling which publishers are preferred, what are the prices which are which are paid and nobody expect 100% completeness and so we are happy, no matter how you get the data, if you get the data out of the financial system, or if you have, let's say, monitoring in your library, no matter how it is. We are happy about every data set we can get for for maybe see. Okay, next slide please. This slide Christoph created some month ago, which shows what we are doing with the data you are delivering. I don't want to get too much into detail but you can see that the UI is a very relevant identifier for journal articles, or for for books, for example. Another very important identifier, if there is no do I for books is the SPN number and everything starts with with the identifiers and if you look at the left side of the of the graph, you can see that we are trying to enrich the graphic data out of certain certain sources like crossref we are enriching identifiers, for example, from your apartment central. We are looking for SSN numbers is an L number for example, we are looking for a unique title number out of Web of Science and what you are getting in return for providing us your data is that you get an enriched file with a standardized set of the graphic data and identifiers. And in 2020 we tried to set up the same way for monographs which was a challenge of course because monographs and articles are not the same thing of course we wanted to show that this kind of enrichment can also be done for books. There are certain problems or challenges regarding books, maybe not solve 200% but in general it is possible to get the same enrichment steps also for books as well. Okay, next slide. If you want to deliver data for open access journal articles. Here are some some some main information about this. As I said before, the data set contains 18 fields and only five have to be live have to be delivered by by institutions which are marked we need the name of the institution we need the period in which the article was published. We need the information how much do you have paid for the article if you're using another currency like I don't know British pound or whatever. You can deliver the original currency as well we can calculate the euro price for you. Very important is the UI of the article and also important is the information if the article was published in an gold open access journal or in a hybrid journal. Okay, this is all we want to have from you and everything else on the right side is then enriched and delivered by by open ABC. In return of course you can use the data for your own reporting systems. But everything we are doing as documented on GitHub. The data are generally visualized in a so called tree map. Maybe you can put on the next button push the next button Andreas. Right. Every institution which is delivering data can can also get a tree map for for the data and this kind of treatment also can be embedded and local websites which is done by by a lot of universities or institutions worldwide. And some of course we can do and do a kind of basic analysis on the whole data set you can see here, for example, information about the average cost per publisher in Europe, and you can can compare it with other publishers as well you can say, for example, I don't know public library of sciences, maybe even, I don't know, maybe cheaper than then for example fun Cheers or whatever. So, so you can make your decisions what kind of publishing do you want to promote at your own institution as well. Also, this kind of information helps you to plan your, your budget of course when it comes to to to to financing open x publishing in your institution. Okay, next slide please. We have the same for the BBC data. We also are five, there are five mandatory data fields and everything else is enriched, which you can see here. And yeah, maybe we can go on to the next slide. There are in the same way they are created reports on GitHub. Tree maps are generated off of the data as well. And then we can have some analyzes about this but again, we only started the BBC data set. Of course, there are some some books in it there are some some records in it but I think it's it's only the beginning only the beginning and and maybe not representative enough to to give figures about the whole market of PCs in this early stage. Okay, next slide please. This is, of course, very relevant because we see a lot of transformative agreements worldwide. And we have the same requirements for the open for for a bit like like a PC data for data out of transformative agreements. But due to the complex calculation of article costs, most data providers don't submit institutional cost data practical in hybrid journals as I said at the beginning. There are total subscription expenditures involved and this makes it very, very complicated to calculate average cost per article in this environment. But with the deal agreement, we started to do this and was a very, let's say complex discussion and we are happy that we can provide now data for the deal agreements in Germany, which incorporate cost data if you can click on the next slide please. You can see here the tree map which we are providing normally for the APC data here for for the deal agreements. And this is the view on the journals, which are mostly used within the deal contracts and you can easily see that for example, the scientific reports or on the one the shimmy international edition, or other journals are on the top for for publications within the deal contracts you can easily see how much they they cost. And if you look for example on the on the institutional level in this tree map. You can see how much every institution is paying for every article, according to the relation between subscription expenditures and article output in this journals or within this publisher so this is very, very, let's say valuable information, because this gives us the information how to proceed in the future with with transformative agreements. And, of course, also again this is not complete for every institution which is taking part in the deal contract but we have a lot of big institutions and you can see the basic mechanisms and the basic challenges we are facing in order to proceed with transformative agreements in the future. All I can do is to say that other library consortia should try to think about how they can provide cost data as well for the articles within transformative agreements it is possible within open APC to to report this kind of information. Okay, I think this was my last slide and I will hand over to Andreas for the integration of open APC and open air and the European open science cloud. Thank you, dear. So, next is to take a look on to the integration into from open APC data sets into open air and then into the European open science cloud. Briefly, the European open science cloud is aimed to have a little environment trustworthy and federated and for an interdisciplinary collaboration and, of course, in a fair manner. So, that's a very short points that we have and we would like to achieve with some steps on one. I will present it only two ones here. So one is the cost estimation for open access publishing for research funders that is one that we are also here. And the other one is an estimating for cost publishing. Researchers so you can estimate the cost for the for publishing your research results. First of all, we integrate the open APC data set into the open air research graph. And now open APC is a part of the open open air research graph and also a service or mayor. And the APC data was enriched with the organization identifiers that we get from war and grid, if we have, and enrich the graph. We have this information and the relations between the entities in the graph. So, the APC data sets have the relation to the publication, and in the open air graph. There are more relations to these publications for auto authors projects of funding streams and funders and so on. We have also the information in the APC data set for the organization, if it's available. And can also relate to these organizations directly. So we can create a full view this APC of these specific articles and so on. This was done in the past month and these APC, the usage of the APC data in the graph was used by the open science observatory in the future and will be used there. And at the moment, there are some other metrics for open science. But the APC data will be available here also. And the other one is the APC data, if the open air research graph know this would also present in the explore portal. And this isn't at a value service for open air and also an added value service for the European open science cloud. And the open air research graph as a core of open air and open air portals and dashboards is also will be also a part of the AOSC knowledge graph core. And in this case, the APC data was also integrated in the AOSC core and could be used as well. Yeah, there. Part of of work is more work to do on this part at the moment. And I think we give a kind of novelties in the later open air nexus webinar here. And the conclusion for this presentation was that the open APC data set is fully transparent and community driven driven since in the last years so we are getting feedback from workshops and presentations like this webinar. And after our presentation is a perfect place to ask questions about open APC APC and BPCs and also transformation agreements. And we have an analytics cube to make analysis. Like you've seen in the tree map or for visualization and all of these information of open APC are published in that GitHub in the in the raw way and in the rich way so you find in the GitHub repository both data parts here. GitHub is part of that. Open APC provides pricing cost transfer transparency to libraries and consortia. And of course, we use these information for institutional reporting and final reporting, as you've seen before, and very important is that if we have more organizations and institutions to contribute to open APC so some more interesting values can be give to the community back. And it's very helpful to have more data sets and end the open APC project. And if you would like to become a part of our community, please contact the open APC at the University of Bielefeld in the address as you've seen before. This is my last slide here before we come to some question and answers reference you see for the open APC website and the GitHub project. Also, the API that can use one from your side. One is the analytics cube of open APC is described at OLAB open APC.net. And also you can use the integrated APC data in the open air graph via the open API open air.u our website has also described how can you make request to these API. And how can you search for for DUIs and if there is APCs on this DUI in the graph so you can request this information from the open air graph also. In this case, I would like to thank you for your joining today and also my colleagues Jochen and Christoph and also with us. And we would like to open the question and answer. Thank you very much. Thank you. Thank you very much for your presentation. We have time for questions and answers. We have one question in the chat but feel free to add more or if you want to put directly the question. Raise your hand and ask to open your microphone and you can put your question directly to the speakers. The question we have in the chat is from Gita. And the question is, is price disclosure not protected by a trade secret. Yeah, maybe I can answer this question. Yeah, I would say it depends of course on the contracts you have with the publishers. But on the other hand, in every country I would say there are freedom of information laws. And so those as a kind of trade off or discussion you have what is more important freedom of information or the protection within an agreement. And there have been a lot of initiatives, I would say in the UK in Finland and so on and normally you are allowed to provide cost information on the article level when it comes to to open X publishing. There is another source for let's say price information in the directory of open access journals for some publishers or some journals. And what we are trying to do with open APC is that we want to indicate or report the costs in reality. And there's costs are something else and then prices. And during the last years we haven't seen any institution or any publisher which is trying to tell us it is not allowed to to give this kind of information it's an open data project and so far we have no, we have had no problems when it comes to to deliver the information about costs for for journal articles. Thank you. I hope this answers the question. We have another question from an eco. How many people are working on processing the data that are submitted by the institutions. One. This is Christopher Chinsky which is also here. And this can only be done because the the workflows behind it are very much automated. Even everything else, the tree maps, the website on on on GitHub or the block. We are using our markdown for it and everything is done automatically or see me see me automatically I would say. Okay, thank you. We have another question from every Ella. Do you know who uses your data and what for. Yeah, there were some some some recent examples which are also linked in the presentation for example the European Commission recently put out a report about open access open access in the Europe horizon project funding phase, and they used open APC data as well for it. Open APC data are widely used in, for example, the metric studies when it comes to to measure things about open access and the costs. In the presentation you will find a recent publication by the metric group also located at Bielefeld University which used open APC data. For example, library consortia are using this kind of data. I know that the people who are negotiating the deal contracts in Germany are using these cost points or price points when it comes to to talk about the the prices for articles in Arabic journals or articles and open access journals. And I know that other library consortia in Europe are using this, this as well. Okay, thanks. And I know if we have more questions from the participants, please feel free to ask. If you have some doubts or if you want to clarify something we have here. The people in charge of opens of open APC and you can make your questions. We have a question from Felix, how regularly is new data added. Yeah, it depends. Normally, I would say that data delivering institutions are providing data once a year. And this is maybe a good way, or a good good, let's say time interval to provide data. Normally, when it comes, let's say for 2020, then in the myth of 2021. Most institution have delivered data for the, for the period for 2021. And I can also add here that our block has recently updated and open APC project receives APC data or BPC data or transmission agreement data so we published this the block. Yeah, that was a question regarding the BPC data. As I said in the presentation, we think that there's only start for BPC data. There are two big, let's say data provider one provider is the Austrian science fund. The data provider is knowledge and that's both institutions have, let's say, a long tradition in funding open access books, I know that for example in Switzerland there is a long tradition for funding open access books as well. Whereas I know in Germany, the the funding of book processing charges. Yeah, let's say started maybe in 2020 or 2019. I don't know how the situation other countries is. So this really a start in this case. Another question from Ike. Would it make sense to add data retroactively. If an institution joins the project. Yeah, so every data is welcome. Also also data from the past year. Another question from Gabriella. I didn't notice. Is it possible to select the data about a PC BPC only for a specific country. It's only done via the tree map visualization. They can see on the right side you can select countries. Thank you. If we have more questions. I think we have answered all the questions in the chat. We also have some useful links in the chat. If you want to copy to save the chat conversation. You can do it. We will also share with you the recording and the slides in order to you to to revisit the presentation and to consult the information about the open a PC. To use the service or to join. If there aren't any questions anymore. Thank you very much for having us and thank you for giving us the opportunity to talk about open a PC today and all I can say in the end. We are happy to to get new data providers to to to make the source even more valuable for all. And if you think about contributing to open a PC, please don't hesitate to contact us and we are happy to to support you and help you. Thank you. Thanks, Dirk and Andreas for their valuable, valuable presentation for for accept our invitation, and I would like also to thank you all the participants for joining these these webinar, we will send you. As I said, the presentation and recording and please stay tuned in the coming open air webinars. Many thanks. Thank you. Thank you, Henry. Have a nice day.
