 So, welcome everyone. Okay, I think we can start. We are already waiting for three minutes in order to have more people joining. We have already 40. I think we will have for sure more joining in the coming minutes. So, welcome to this open air provide community call. So, this is a community call, an online meeting targeting all the open air content providers from repository managers, managers, editors. So, those that are part of our infrastructure contributing with content. So, we have decided last year to start organizing these community calls in order to have you on board to provide us feedback. About the services that we are offering via the open air infrastructures and also to have your contributions to the development of the services, of the guidelines, of the different areas that we are all working in open air and all the community benefiting. So, the idea of these communities to have it all first Wednesdays of the month is to mainly to share the just asking also for you to mute your microphones and that could you also monitor that. So, the main idea is to provide updates so to let you know about the the main developments that we are doing in open air some novelties, and we all we always have one main topic to discuss. And this, this time will be on the on the on the disk space crease implementation for open air. But every meeting we have one main topic plus all the recent novelties and the recent news about our development so I first I start and Pedro Prince from the from open air from the University of Mino. And we are responsible for the provide service and we, we are in charge of this community call with the rest of, of the open air, the open air team. So, and I will do this first part to tell you about some good news that we have for you about the provide service, and then the main topic will be about the space crease, and we will have our colleague Andreas from the University of Bielefeld and Andreia Bolini from for science that will present the implementation of the crease guidelines in the in this in this space crease. So what, what do we have to tell you this this meeting usually we have recording this meetings you can you can check later and we are going to share also the slides. So, as we told you in last in the last meeting we are doing a kind of redesign of the dashboard of the provide service and the good news are that we are, we are almost done. We are already in a version in in in providing beta in beta to share with you, but the next Tuesday on the coming week on Tuesday, on the 7th of April, we will put it in production. We want to have some time, kind of two weeks to test with some users, but we have this ready to go to production and we are quite happy. It was something that we really wanted to have we receive several contributions in feedback from from users and and and we have redesigned it also to align with them with a new image and new branding in an open air but also to correspond to the some of the feedback that we have received, but we are happy to also to engage with some of you to contribute to this two weeks of revision of this new new version. So, we are really happy and within this release, we will finally have the validator for for for Chris systems, something that we are promising since mid last year. And finally, we have it, we are testing it in better but we will present it. It's the first version, we can say it's more or less a better version of this validator but we will have it also within the release of this production of this in production of this new version so next April 7. So, for this, for this redesign was quite important all the feedback that we have received from from you from different initiatives so some workshops that we have organized at the national and international level even if last year in the during the open conference or in some national events that we have we have done and we have received some feedback and based on that feedback we are producing now some some enhancements in this in this service. But we want, we want more so we want to have your contribution. We are quite happy with this version that we are going to release the coming week. But we want to have your feedback so between the 15 of April and the end of April, we will run a series of of user tests with our provide user board. So, if we, you are available to contribute we have already an interesting team of repository managers or other managers to contribute to this user board but if you want to contribute and we are here also to invite you please send an email directly to me offering your help to participate in this in this test that we are going to run, collect your feedback, we are going to ask you to perform some, some specific actions using our new version of the dashboard and then we will collect your feedback and this will be quite important for the improvements that we need to do within this process. We wanted to do of course in a better stage, but we are pushing to have within production because we, we have three or four main issues regarding the communication with with with providers that we want to put in production. As soon as possible so this is why we are moving fast from better to production, but we are using this April this month this first days of in production to test some things and to quickly free fix it if needed. So we need your help here please contact me. I'm giving this speech just to convince you to contribute to this to this task is not a difficult task we will ask you for a meeting of an hour meeting to run some some some some tests and then often in an hour also to contribute within us with a survey to answer a survey and then with some tasks additional tasks so it's not a lot of effort but but it's it's quite important for us. So we will have this new version. On the coming week, when we are happy for that I just want to tear that the more or less the new layout that we are going to release we will have a completely new brand in the service, the homepage we are providing more information we also have an about page for those that are not part of the service to better what we are offering but but the most relevant change I think it's the internal parts of when you log in to the to the dashboard where we are we have we have where we are now offering really a dashboard view so that we can you can manage and you can play with the data that we are offering so we are quite happy if you want to test it so we it's not everything done yet but you you can access the better instance that we that we have so you can access access and you can already play a bit if you want but it's not 100% what we are going to have in production, but you can already test it tomorrow we will improve a bit this better version so you can you can wait until tomorrow if you want, but please access. And you can you can see that we so we are trying to to have a more friendly interaction more easy to use dashboard and where you have some generic functionalities regarding the registration the validation and the notifications and then we are providing all the specific information for each data source that you have registered in your in your account so this case I am I'm just sharing that I have a screenshot from University of Minio dashboard where we have some some numbers and then you can navigate through the aggregation history all the metadata enrichments and the user statistics. So we are quite happy and I hope that you you will benefit a lot from this new version and I hope that some of you can also contribute to this new version and the tests that we want to run. Now I will stop my my my presentation I will come at the end so I will give the floor to my colleague Andreas from University of Miller felt that will introduce this main topic. Stop sharing because I think Andreas, it's going to share the screen so I give the floor to Andreas, and then he can introduce himself and then the variable in the also and then introduce this this main topic that we are discussing today. At the end, we have time for questions for your comments about of course this presentation that we are going to have, but also about other issues that you are facing with the way we provide so we have some time to answer also about this this topic and and other things from our services for content providers. So there is thank you very much for preparing this this this main topic of the call today. Thank you Pedro and thank you for introduction to this community call today. And it's nice to see the new dashboard so I think there's also some upcoming community calls on this dashboard or so so. Thank you. And I welcome you to also to the fifth community call today from my side. I will have this presentation together with Andrea bullini from for science. And he is certainly in the community. And Andreas the chief technology and innovation officer at for science in Italy. And he's also the deputy leader of the Zerife task force of euro Chris, and a member of core next generation working group, and long long term, the space cometer. So, Andrea, we are happy to welcome you here in this community call today, especially in these times that Peter mentioned in the beginning. My name is address journey and I'm from University of Bielefeld in Germany. And we are responsible for the guidelines in open air, especially in these tasks and this topic here today for the Chris guidelines and in the last year. We have development on the implementation to compliant with the open air Chris guidelines. So, our agenda for this main topic is short introduction about the guidelines. Then I will take over to Andrea. And for the Chris the reef integrated Chris a reef overview implementation of the guidelines in these ways Chris. In this phase of implementation in the last year we have some pilots that we present here. And at the end, some conclusions lessons learns and space for question and answers at the end. So, the open air guidelines for Chris managers have long term evolution. It starts with a version one in June 2015, and we have us to an order X XML, the reef standards. And in end of 2018, we release the actual version of the Chris open air guidelines. This has some minor extensions from the version that's released in the mid of 2018. And the most important thing is to have more personal identifiers and the documentation is improved on this. So, why we choose here the space Chris, what are these days and the space Chris module. And as you know, this base is the most popular repository platform in the world, and is used in many kinds of things we have more than 1,500 installations around the world. And that in the space community, especially a module for the space Chris for current research information systems that specifies these topic, especially and extend these open source software. And this is why we choose why we would like to push these community to have the open air guidelines as a standard out of the box in the space Chris. So, the main objectives for the implementation in the last year was to realize these new guidelines for Chris managers, as I said in the box. This gives the Chris repository managers opportunity to expose their information to open air and to use all services behind open air for your repository. So, I will take over to and give the floor to Andrea to introduce or give an overview about the Chris very format. We will start with a very quick introduction to the new series format for the Chris guideline. The most important fact is then for the new version of the guideline, we have introduced a new service XML format that open to cover additional entities compared to the version one of the guideline. And the entities that are now covered are publication, patents, products, organization unit, people, projects, events and equipment. So you can see that using the Chris guideline, you have a much more rich graph of data information that you can exchange with open air. It's not only limited to research outputs of publication and research data, but you can also describe your organization, person and activities. The other important fact is then the new format reuse existing vocabulary from other community, most important from the core communities or the core vocabulary. Using the Chris guideline, the institution will be able to exchange the as much rich data as possible and one of the important thing is then we want to keep easy to use of this information. So an improvement compared to previous version is that now each record is self-contained. This means that when you expose your publication record in the new series format, all the information about linked entity like author, project, equipment are embedded in the XML of the publication. This will reduce the need to go over different and point to ask multiple requests to build the set of the tail of the record that you really need. How we have done this implementation in the space Chris. So one of the first tasks was to improve the out of box configuration for the space Chris. This space Chris has flexible data model. So you are not buying to a specific data model to specific entities or attribute. But you can decide to collect information that you really need and that you are able to provide in the system. But out of box we provide a starting point or configuration that will match the usual needs of institution. So the first task was to improve this out of box configuration to include all the data that was recommended by open age to to have a good exchange with open age. The second task was to extend to IPMH server of the space Chris to include other than publication also to Chris object. So now with this version you are able to index into IPMH server and so to expose to open age also your project person organization and so on. Again has to in this space Chris in a Chris system to information space is very rich and you have many connected object is more about a graph of object than a single record. We have extended IPMH mechanism so that we can embed information from linked object inside each specific record. Of course we have provided a default mapping so that the information that are stored in this space Chris are exposed in a compatible way to open age and all this effort has been implemented in all the current version of this space Chris. So this is included out of box in the space Chris five that is the most used version the space Chris six, but also into ongoing development of the space Chris seven. So this development are available in all the present version of the space Chris hotel IPMH look like in the space Chris now. So, in green in this diagram you see the common element that we share with the basic space software. So this space deal with community and collection that are usually user to create or I set and have item that describe usually research output so publication or search data and patterns. In this best case we also have what we call research profiles that are person, the organization units, the projects, and some dynamic object that can be used to represent events, journals, equipments and so on. All this information now are indexed into IPMH server. And for each of these empty you get at least one eye document that technically is stored into x y format. In this document you have all the metadata and also information about the beast stream that are attached to the record. Some important fact is that this space Chris also provide the hierarchical metadata. And these are used in this space Chris to manage the terminal relations problem. This is the case when you have one publication for instance and you want to describe to collect also the information about which affiliation was used by each author to sign the specific publication. So in this case we talk about ternary relations, because of course you have the publication you have the person and you have the organization unit that are all connected together. Other than these embedded information is a special eye document also includes dynamically generated content. More specifically we use this infrastructure to dynamically detect, which is the serif type of the space Chris entity that we are going to index, so that we know that the research profiles in this space Chris are used to represent a person in the space Chris world. But also we know that the dynamic object journals is instead a different kind of publication for for a series. Other than that we provide a set of configuration files for this space Chris that allow you to map specific aspect of the open air guideline. There are some solar query that are used to create virtual set, virtual ipmh set because the guideline mandate for set for each entity so the open air guideline for Chris manager required to existence of person set where all the person record are exposed and organization set where all the organization unit record are exposed and so on. Other than that we have a mix of sheet file that translate internal metadata structure of the space Chris to open air serif format so the serif XMR presentation for open air. This endpoint is available out of boxing on the space Chris now when you saw one of the latest version. And you have a specific context into why the game age server that is named open air Chris by default where this guideline are implemented. So let's go to explore some example to make this thing more clear. We have an official demo for this place please available and on this demo you will found on active to the open air Chris gay lining point. So the first example come from the guy line itself so is a publication record. It's a publication record from the open air project. As you can see there are several author and there is a reference to a project again so to the open air project. So in this case we have a less one publication link it to one project and this publication is linked to several books. Of course this person are linked also to organization units so their employment and the project has received some funding. So here you can see that you can access the representation for each entity in the graph starting to look into the publication record. So, here you have the record in the format for the publication, where you see a lot of detail about the publication like the title publication date, the volume issue and other specific of the publication. I am highlighted to section one is related to the authors and one that is related to the originated from our element. So the authors element include a sub element for each author in the publication. In this case you will see the detail about the Nicos houses that include some interesting information. This one you have all the known identifier of this author. So you have the orchid ID, you have the researcher ID, the Scopus author ID directory in the external that described publication. These allow you to have much more accurate exchange of information. But also you see that this level of embedding is not limited to just one level. Inside the publication you have the author, the author type include information about the person, but also the person information include element about other entity in this case for instance the affiliation. So, here you see that this person was affiliated with the National Hellenic Research Foundation, and you see the information about the organization unit that is linked, but also information about specific affiliation records such as the start date and eventually an end date and so on. The other tag that I have highlighted in the publication record was the originated from. It's because the publication have a reference to the project. So here in this tag you see all the detail, the most relevant detail about the project. So you have the title of the project, second generation open access infrastructure. You have the information about the team that work in this project. In this case, it was just a fake person from our demo, but you also see that embedded are funding information. So in the OICER funded element, you find information about the funders, so the European Commission in this case, where there are more detail in the embedded organization unit element, but there are also more detail about the funding itself. So you have the detail about the received amount, the type of funding received and this is also structured in a hierarchy so that the funding can include and be part of other funder funding that in the case of the European Commission is the seven framework program. So this is the Nicos record in this space crease that you also have already seen in embedded in the publication OIC record. So in the public page of this space crease we have a profile where you see that there is the full name, hierarchy, or key, the scope, there is the information about the affiliation. And of course there is also the back reference to the publication that was altered by Nicos. Again, also the person record is exposed as a separate OIP image record. So you can get the detail about the specific person also directly and not only look into the embedded information in the publication. And as you see here, the person record contain again the detail about the person, so like the family name, the first name, the full name, all the identifier, orchid, research, ID, scope, and so on, but also embed information about the affiliation and the organization unit. And the organization unit itself also have a separate record on OIP image endpoint. This also allow external service to collect information that they really need from your crease system. So if an investor is only interested about your researcher, they can just grab the researcher information, the researcher records from your system without care about publication and other entity. The second example in the demo is about a dataset. So what is named a product in the service world. And this product reference a project. So this dataset was collected for a project and was produced by some specific equipment. As you can see here, you have the endpoint access to your OIP image record for each of these entity. We can see the detail about the dataset. So again, the dataset in the service world is named a product. So you have a representation of this record as a nice service product where you have type of product using to call vocabulary, you have the title, the name, identifier. And you have the reference from this product to the project that is embedded again in the product record. And also you have the reference to the equipment. So here you find the generated by elements that embed the equipment information that are also available as a specific OIP image record and dependent OIP image record. In the case of the equipment, for instance, there is also a reference to the owner of the equipment. So the organization that owns the equipment. We have made this implementation thanks to the collaboration with three pilot institutes, institution in Europe. One was the Technic University of Hamburg, Cambridge University of Technology that don't yet run the system in production because we are solving some final issue with local customization. The other two institutes was the Cyprus University of Technology that have already deployed the solution production. So this is a public endpoint that you can explore where you can access all the information about the Cyprus University of Technology. And the same apply for the University of Trieste that have installed the solution in their own open repository. It's named OpenStar. And the nice fact about the University of Trieste is then this endpoint is already used by another project, Italian regional portal, UNTF IG that also is built with this base Chris and aggregate data from three different university in this Italian region. This portal used OIP image server to collect information about to aggregate information about the University of Trieste with the other university. So other than expose this information for this additional project, we have also implemented an investor client that is able to grab the content. We have some slide from the Eurocris meeting in Newster last November of last year that was the result of the pilot phase. The interesting thing about this slide is what we and each institution learn during the pilot. So in the case of the Hamburg University of Technology, we improve a lot the initial solution because looking to tell very complex data with a lot of local enhancement to the model and customization. We found some discrepancy at starting the data that was exposed to the OIP image and data that was really stored in the Chris system. And these analysis help us to improve the solution and all these peaks are now included in the current version. The Cyprus University of Technology has adapted this solution with the aims to expose their complete set of information to open air. As you can read, University of Technology of Cyprus have a lot of projects funded by the European Commission and the other. So the benefit for them is to be able to expose this information to open air and they really look forward to see this information available to open air portal. I have already said something about the University of Trieste. So the University of Trieste is one of the most hold the space installation and the space Chris installation data signs more than 10 year. And one of the goals to benefit that for them to use to this implementation is that they are now able to expose all the information. So not only publication, but also the research profile, the organization, the project events, the dataset to open air, but not so only to open air. As I really said, an Italian regional project also used the same endpoint to collect this information and to create a regional portal for the research. So my last slide is about the other connection that exists between the space Chris and open air. This is only the last implementation that we have provided to improve the integration between the space Chris open air. Other than Chris Gail line, the space Chris also support the literature repository Gail line, the version three as a normal space repository. But the good news is that we have also implemented the compliance with version four for literature repository. And this is currently available as a page for the space and the space Chris, and that we have proposed to integrate into the next minor version of the space. We don't know yet if they will be included or not into this basic space versions or in the space five dot 11 or six dot four. But for sure, this will be included in the in the next space Chris version. So after the release of the space five 11 and six dot four, the space Chris version will include the support for literature repository version four. This space Chris also implemented that archive guideline version two, that mean expose your record your data set in using the data side schema version four. And using this space Chris you are able to use the open air project database as an authority during the submission process so that the researcher don't need to input manually the title of the project or the grand number, but they can just look up in the open air project database. And also out of box you get open air statistics plugin already bundled with the space Chris software so the only thing that you need to do is to apply for an APK with open air and add your APK to the space Chris configuration file. All these aspects are documented a bit on the latest wiki on the official this space wiki. But of course the presentation is always something that can and should be improved. Andreas, if you are still able to help me, I leave you the floor for the conclusion. So, thank you Andrea, and for this also implementation in this space Chris here. Oh, I can see Pedro slides at the moment. Can I share my screen. Pedro. I know that you have two more years. So, this was also implementation. And now feature rich things in the space Chris at the moment so this is a very good start to set up the space Chris in your, your institutions and my last words to the implementation of for science that we have seen is that for science have won the tender in the last year. To implement these guidelines for into the space Chris. So, the next question is, you have these best Chris up and running and how can you register register your Chris system in our mayor. At the moment in the production system and also in better. You will see Chris systems registration was stay tuned. So, at the moment, please. There's another work around for this so we are work hard to get the registration up and running. But there are some implications there and so in the at the moment if you would like to become a member. I sent an email to help desk at University of Bielefeld. You see the email address here. And the requirements what we need from your side is the name of the system. Your base URL to the endpoint. And eventually the sets that we can harvest from you so Andrea said there are a lot of sets like publications, patents, organizations, funding, and so on equipment. And if you like only that we that don't may have us the publication sets and the patent so please tell us in the mail also. So, but we are in the face to see these registration with and we are strengthen strongly in collaboration with Euro Chris. Euro Chris has set up in the last year. registration for research information system called dress. And here is a short screenshot from the Euro Chris website and shows up the act at the moment. Yesterday. When I take the shots. You see a lot of Chris systems around the world. So you see here, a lot of Chris systems in Europe, you will, you see a lot of Chris systems in India. And I think it's was going up the next coming upcoming month. And we are going to find a way with together with your Chris to register a Chris system in open air. So, this was a tender and there are some lessons learned and conclusions on this. And we have seen over the time in the last year that we have some limitations in the guidelines. And we refine the guidelines at the moment. It's since it's now good to have these these space Chris implementation in the space. So you can exchange your research information directly with open air. And you can also use the services in open air for your publications and other kind of records from your space Chris system. To get notified from broker about enrichments of your metadata are and so on so in the community call in February I think we have dedicated presentation about the broker. So these discusses really available. And then you'll be see license is open source is implemented as Andrea said, and if you have feedback for us about the guidelines of Chris managers, especially we have a Google document without any authorizations you can comment this Google document and explain your issues that you have with the guidelines. At the moment there are some issues there, please you can also take a look on this and you see what we are working on at the moment. You can also send an email at guidelines at open air you for feedback and also for we have the issue tracker in GitHub for these guidelines. And we collect the information from the Google document and work with the issue tracker in GitHub. The feedback channel for these base Chris is also in GitHub. And is under for science these base and issues. My Yeah, one moment I will, I will finish. Okay, I will try to apply to some question that I read on the chat, but I gave my sorry for the technical issue but I'm not able to are from your side so it's a bit hard to do that. I read a question about identifier for organization unit is something that can be done in itself but is not not available in the current guideline as actual example so if you look to the GitHub repository for issue that was referenced before, you will find a couple of issue discussing how to express exactly express dis identifier for organization unit. I will put one link in the chat that is this issue describe some of the identifier that we are looking for for organization unit that of course include Roar, Greed, Izny and other common identifier. So you can expect to have this solved in a next version, probably minor version of the guideline. Thank you. Guys I don't know if you want to conclude something more about the feedback so if you want to jump in just I'm sharing the screen but but you can you can just so we are already in this community call with Andreas do you want to add something else to finalize your presentation this final remarks about how can people contribute to provide feedback or not. I'd like to thank you all and if you have any questions you can also send an email to may help desk at University of Bielefeld and as Peter mentioned in the beginning. So, the Chris validator I think there's a. This is not discussed yet. This very narrow, this will be exceeded the time limit of this call we have one hour at the moment, and especially I think there's another dedicated call on the validation validation service and validator in the provide community call. And this cannot only focus on Chris system this can also also focus on literature guidelines and so. So thank you very much. And Pedro, your floor. So, so I think this is important. So we have a clear roadmap here for the integration of three systems in open air so pre systems are also an important community from from our open air community of content providers so we are already working in a clear roadmap with all the repository managers from richer to maybe from rich to repositories but now we can also do this in a clear we having a clear roadmap and clear tools to support also Chris system managers, having this use cases presented here, and having all these channels of communication and plus also the validator available in the in provide on the coming week. And so, thank you for joining this call. I just want to highlight to finalize that so every month we have this committee calls next committee call will be on the 6th of May, at the same time of past two. European time. And I also want to invite you to if you are not yet a subscriber, please subscribe the content provider newsletter so we are sending every month also on the day before of the community call. If you are already a subscriber please disseminated through your networks at the national level this quite important also to, to have other people in your country's also to subscribe the newsletter and to participate in the community call so if you don't have any other questions, thanks for joining this community call I hope that it was useful at least just to know about some novelties important novelties a new layout a new version of the dashboard next, next week, and about this important use case from this place Chris to have more systems on board in open air so many things all and stay strong in this difficult phase for all, and then be safe. Okay, bye bye. Thank you very much.
