New documents that present OpenCitations’ mission, unique benefits, present status and future plans

Posted on August 10th 2022 by Chiara Di Giambattista

More than a year ago, Ginny Hendricks, Director of Member & Community Outreach for Crossref, and a valued member of the OpenCitations International Advisory Board, published on the Crossref blog the post “The road ahead: our strategy through 2025”. In order to describe all Crossref’s principles and activities, Ginny presented the Crossref strategic planning framework as a diagram summarizing Crossref’s statements, key messages and truths. The clarity and immediacy of the diagram were such that we adapted it to present  OpenCitations’ own statements and goals. The resulting poster “OpenCitations – what does the future hold?” was presented by our Director David Shotton at the OASPA2021 conference, and can be found in this blog post.

Although the poster offered a wide overview of OpenCitations values, unique traits, benefits and plans, it differed slightly from Ginny’s original diagram, in particular because it lacked a “Mission Statement”, scattering the relevant information within the “Values” and “Principles” boxes. Indeed, at that time (September 2021), we didn’t have a clearly defined Mission Statement.

Nevertheless, the creation of that poster was crucial in helping us start to articulate more clearly the purpose and meaning of OpenCitations. As David underlined in his post “From little acorns…a retrospective on OpenCitations”, since 2018 OpenCitations activities have progressively increased and, with them, the number of related journal articles, conference papers and technical definitions. OpenCitations’ involvement in international networks and collaborations (such as SCOSS and the OpenAIRE-Nexus project), together with our need of identifying and reaching out to new stakeholders to assure OpenCitations’ development and sustainability, has made it necessary to publicly define OpenCitations’ mission, unique strengths and next developmental steps.

After numerous revisions, aided by wise advice from members of the OpenCitations Advisory Board members, we’re now happy to publish the following three OpenCitations documents:

OpenCitations Mission Statement,

The Uniqueness of OpenCitations   and

OpenCitations – Present Status and Future Plans,

which together provide a summary of why we exist and where we are heading.

We are particularly proud of the definition of OpenCitations’ primary mission, namely

to harvest and openly publish accurate and comprehensive metadata describing the world’s academic publications and the scholarly citations that link them, and to preserve ongoing access to this information by secure archiving.

The Mission Statement also presents brief descriptions of the OpenCitations context, our vision, our value proposition and our relationship with the community and stakeholders.

The Uniqueness of OpenCitations provides the answer to the question ‘Why choose to use OpenCitations?’, and is a detailed presentation of OpenCitations’ benefits.

OpenCitations – Present Status and Future Plans summarizes OpenCitations’ ongoing activities, that can be quickly visualized on our public roadmap. It also introduces the OpenCitations Working Groups, served by the members of the OpenCitations International Advisory Board, which are currently working on the themes of governance evolution and community building, with the common purpose of driving OpenCitations along the path from being a ‘sustainable infrastructure’ (in POSI terms) to being an enduring community led and financially sustained infrastructure.

In fulfilling our mission and reaching our goals, the support and vital interest of our community members is fundamental. We request that you, as a member of our community, provide us with feedback on these documents and the ideas they contain, or indeed to ask for clarifications, to help us improving our mission and our communications to explain it. You can reach us here: contact@opencitations.net.

Thank you!

Two years of achievements within the ‘SCOSS family’ (and it’s not over yet!) 

Posted on August 10th 2022 by Chiara Di Giambattista

→ Next post: New documents that present OpenCitations’ mission, unique benefits, present status and future plans

In March, The Global Sustainability Coalition for Open Science Services (SCOSS) celebrated, together with the generous funders and the projects involved (including OpenCitations), the achievement of an amazing milestone: a total of 4 million Euros raised so far for supporting the growth and development of Open Science Infrastructures. This significant sum is not just a number, but a concrete sign of the commitment of numerous institutions all over the world to ensure the success of vital organs of the Open Science ecosystem. Thanks to the pledges recently made, the new infrastructures selected for the third SCOSS pledging round have now started developing their services and can now look to the future with more surety.   

At the end of 2019, OpenCitations was selected by SCOSS for its second pledging round, and since then much progress has been made. As the OpenCitations’ founder and director David Shotton recently stated: 

“OpenCitations is growing, thanks to the generous support from our members and donors, and we thank SCOSS sincerely for bringing us into contact with them. The citation coverage provided by OpenCitations is now approaching parity with that of the leading commercial citation indexes, and our ambition, within the next five years, is for OpenCitations to be routinely used by our worldwide stakeholders as their primary source of comprehensive scholarly citation information”.   

In 2020, OpenCitations monitored the achievements of the first year of SCOSS support and shared the most important updates in a blog post. After a review from SCOSS Advisory Group and the SCOSS Board, the OpenCitations 2021 report to SCOSS is now available in the SCOSS May newsletter. We’re proud of the successful developments that 2021 brought with it in many areas, from the technical enhancements to OpenCitations to its new supporters and partnerships.   

After a two-year-long collaboration, we in OpenCitations recognise that one of the most precious benefits of being part of SCOSS is working within a community: SCOSS not only provides a framework but also a real family of supportive institutions that support the Infrastructures during their growth and provide a safety net if troubles occur along the path. The bi-monthly meetings organized by the SCOSS team enable dialogue with the other infrastructures within the same pledging round, while presentation and promotion to the institutions worldwide are fostered by participation in webinars and conferences. During  2021, OpenCitations participated in 16 events, and in 5 of them (LIBER Webinar 2021, JISC Webinar 2021, LIBER Annual Conference 2021, Open Science Fair 2021, and Open Access Tage 2021) OpenCitations’ director Silvio Peroni gave talks together with the representatives of others infrastructures involved in the SCOSS second pledging round.   

In compliance with the POSI principles, SCOSS encouraged OpenCitations to set up an open governance structure. As described here, the organizational bodies included in the OpenCitations present governance are three: the Directors, the International Advisory Board, and the Council. Although executive power is still currently vested in the hands of the Directors, in the last two years the OpenCitations International Advisory Board, a committee that now comprises nine Open Science experts from different professional and academic backgrounds, has had a crucial role in guiding the OpenCitations activities, and it is now working on strategic developments in terms of collaborations, policies, support and governance. Moreover, last December OpenCitations organized a Webinar in conjunction with its Annual Meeting to present and discuss with the OpenCitations Council members OpenCitations’ recent developments and future plans.   

OpenCitations is highly reliant upon the connections we have created and on people working together: thanks to the support we received throughout the last two years, the OpenCitations team has grown and now includes six people employed by the Research Centre for Open Scholarly Metadata at the University of Bologna, the administrative body for OpenCitations. Besides the previously announced appointments of Claudio Fabbri (Research Manager), Chiara Di Giambattista (Communications Director and Community Development Manager), Giuseppe Grieco (Software and Systems Developer), and Arcangelo Massari (Software Developer, working within the OpenAIRE-Nexus project), early in 2022 Ivan Heibi, Ph.D. candidate at the University of Bologna, joined OpenCitations with responsibility for the technical infrastructure, and Arianna Moretti, who recently graduated in Digital Humanities and Digital Knowledge, joined as a software developer. This enlarged team, involving young and motivated researchers, is working on numerous projects to be announced later in 2022. You can learn more about OpenCitations’ ongoing activities on our public roadmap.   

OpenCitations’ aim continues to be the publication of open data describing the bibliographic citations linking global scholarly publications, with depth and scope, while maintaining the highest standards of accuracy and provenance. Most importantly, OpenCitations services will always be free, making global scholarly citation data available at zero cost and without restriction for third party analysis and re-use. 

With its support, SCOSS has been helping OpenCitations to pursue its mission and spread the benefits of Open Science. However, 2022 will be the last year of the three-year-long support ensured by SCOSS. OpenCitations activities won’t stop in 2023 — indeed there still are many long-planned activities that we hope to initiate in the near future, given sufficient resources. This is why OpenCitations requires ongoing support from the scholarly community. All the information you may require to start helping us financially is available on the OpenCitations website:  https://opencitations.net/membership 

By supporting OpenCitations, you will embrace and sustain the ideals and vision of Open Science, and you will help in creating a more open, democratic and fair knowledge environment.

OpenCitations and EC funding: OpenAIRE Nexus and RISIS2

The incentives for new OpenCitations innovative solutions

Two years ago, in their canonical 2020 QSS paper on OpenCitations, Silvio Peroni and David Shotton anticipated the creation of the new database, OpenCitations Meta, able to “offer a faster and richer service” by storing bibliographic metadata “in house”. Meta would “avoid duplication of data by efficiently permitting us to keep […] a single copy of the metadata for each of the bibliographic entities involved as citing or cited entities in the different OpenCitations’ citation indexes”, would remove the requirement for potentially slow API calls to external metadata sources such as Crossref and ORCID, and would enable us to index citations involving entities lacking DOIs.

Important synergies to achieve goals

Today, thanks to the recent involvement of OpenCitations in two EC-funded projects, the OpenAIRE-Nexus Project (Horizon 2020 EU funded project, GA: 101017452) and the RISIS2 Project (Horizon 2020 EU funded project, GA: 824091), the development of OpenCitations Meta has commenced, with a planned release date later in 2022.

The OpenAIRE-Nexus project started in January 2021 to embrace and expand the operation of a portfolio of thirteen services, provided by OpenAIRE infrastructure, public institutions, organisations and universities, classified into three portfolios entitled PUBLISH, MONITOR, and DISCOVER. The OpenAIRE-Nexus portfolios focus on the demands of the three main categories of the research lifecycle.  Therefore, OpenAIRE-Nexus makes sure such services are integrated to provide a uniform Open Science Scholarly Communication package for the European Open Science Cloud (EOSC). Within the OpenAIRE Nexus project there is scope for producing not only support materials (factsheet, guides, video tutorials, demos) but also training sessions where the services in the three portfolios will be showcased, anticipating the EOSC onboarding process. The role of OpenCitations in the project is to provide open bibliographic citations, and interconnect and integrate (and vice versa) functionalities with the  OpenAIRE Research Graph and more OpenAIRE-Nexus services such as EpiSciences, OpenAIRE MONITOR) the core component of OpenAIRE infrastructure and services and of the EOSC Resource Catalogue. 

Additionally, we are happy to announce our recent involvement in the RISIS2 Project. The Research Infrastructure for Science and Innovation Policy Studies (RISIS) is a project funded by the European Union under a Horizon2020 Research and Innovation Programme. RISIS2 involves 18 partners working together to create and maintain a research infrastructure for the field of Science, Technology, and Industry (STI) Studies, and to build an advanced research community in this field. OpenCitations’ contributions to RISIS2 will include not only the creation of OpenCitations Meta but also the development of a new citation index of open references, the OpenCitations Index of DataCite Open Citations (DOCI), which will be based on the open reference holdings of DataCite and, together with COCI, will be cross-searchable through our unified OpenCitations API.

Lessons learnt so far

A year into the OpenAIRE-Nexus project, we have found that one of the most significant benefits for OpenCitations is our involvement with this wide cooperative network of European research infrastructures, services, and communities, within which we can exchange experiences, ideas, and knowledge, and discuss any challenges and outcomes with our colleagues. More importantly, OpenCitations becomes positioned within the Open Science ecosystem, as a valuable innovative infrastructure with strong proof of integration and interoperable operations. Being part of the OpenAIRE-Nexus team has opened up more future challenges and expectations, and raised the bar for the inclusion of more functionalities of value. Thanks to the dedication of its efficient communication team, OpenAIRE is also helping us by communicating OpenCitations services to additional users and stakeholders, by inclusion within the comprehensive OpenAIRE services catalogue, by releasing an OpenCitations factsheet and by permitting us to present the latest information on OpenCitations through established events (i.e. Open Science FAIR 2022). FAIR and openness of information is our motto, and we strongly promote this through all our activities.

Expanding our team

As announced in our previous blog post “Five reasons why 2021 has been a great year for OpenCitations”, the support we receive from the EU as part of OpenAIRE-Nexus has enabled our recent appointment of Arcangelo Massari, a software developer who is now playing a crucial role in the creation and development of OpenCitations Meta.

As the year 2022 progresses, we look forward to bringing you further information about other new goals for OpenCitations, made possible by the support we receive from our numerous partnerships.

Five reasons why 2021 has been a great year for OpenCitations

2021 is just behind us. Since January is “the Monday of the months”, as F. Scott Fitzgerald once wrote[1], it’s a good time to take stock of what happened at OpenCitations during the past year.

Among the numerous events, achievements and challenges that 2021 brought with it, we want to highlight five milestones which make us proud to look back:

1. We extended our coverage to well over one billion citations

During 2021, OpenCitations’ largest index COCI (the OpenCitations Index of Crossref open DOI-to-DOI citations) was able to include for the first time the citation links involving references that had been opened at Crossref by Elsevier and the American Chemical Society, thereby greatly expanding its coverage. The last release of COCI (November 2021) is based on open references to works with DOIs within the Crossref dump dated October 2021, and, as a result, COCI now contains information on more than 1.23 billion citations involving almost 70 million publications.
A recent analysis by Alberto Martìn-Martìn (Facultad de Comunicación y Documentación, Universidad de Granada, Spain), published on the OpenCitations Blog in October, shows that the citation coverage provided by OpenCitations is approaching parity with that of the leading commercial citation indexes, Web of Science and Scopus, offering a viable alternative upon which to base open and reproducible metrics of academic performance.

2. OpenCitations team grew

Last summer, we appointed Claudio Fabbri as our Administrator and Research Manager to take responsibility for the day-to-day administrative and financial activities of OpenCitations; Chiara Di Giambattista as Communications Director and Community Development Manager to take care of all communications and community interactions made on behalf of OpenCitations; and Giuseppe Grieco as our new Software and Systems Developer to take charge of technical development related to the OpenCitations services.

Thanks to the support from the OpenAIRE Nexus project, the team has also recently welcomed Arcangelo Massari as our new Software Developer to take care of the development of the new database OpenCitations Meta. We anticipate further appointments during 2022!

Our International Advisory Board met in November, and we thank its members for the valuable advice they provided. The Board will meet again later this month.

3. We participated in many international meetings

During the past year, OpenCitations’ directors Silvio Peroni and David Shotton took part in numerous international conferences, webinars and workshops, including the LIBER Annual Conference 2021, the OS Fair 2021, OASPA 2021 and FORCE2021. These provided excellent opportunities to describe and promote OpenCitations, to reach out to new potential stakeholders, and to discuss with other experts the main themes of our activities and plans as they relate to Open Science.

The year ended with a bang, with the announcement during the closing session of FORCE2021 that the 2021 Open Publishing Award for Open Data had been awarded to OpenCitations.

4. We received a world of support

In 2021, thanks to our involvement in the SCOSS funding campaign and to our commitment to reaching out to the libraries and universities potentially interested in OpenCitations, we gathered a wide international community of stakeholders and supporters around us. We are deeply thankful to the 6 consortia and 56 institutions across the globe which are now supporting us financially, thus making it possible for us to enhance our services and expand our team. You can find the full list of our supporters on the OpenCitations website and in this recent Thank You video:

Additionally, in January 2021, we started our involvement in the EC-funded OpenAIRE Nexus project, bringing us into closer collaboration with our European colleagues and infrastructures, including OpenAIRE. The main aim of the project is to create a framework of services for assisting in publishing research, monitoring its impact, helping promote its discovery, and integrating it into the European Open Science Cloud (EOSC) “for the benefit of the open science community worldwide”. In OpenCitations, we’re thrilled to be part of this collaborative project by providing open bibliographic citations as part of the open data components of OpenAIRE and the EOSC.

5. We set the stage for future developments

Thanks to the research grants and the support and endorsement we have received from the international scholarly community, we are now working on a variety of new services, thus setting our goals for the coming years. In particular, we want to enhance OpenCitations partnerships and dialogue with the scholarly community; to collaborate with colleagues to develop new services that will expand our citation coverage, including new OpenCitations indexes of NIH-OCC, of DataCite and of other sources of open references, that will all be searchable through a single API; and to create OpenCitations Meta, our new database that will hold comprehensive bibliographic metadata of the publications involved in our indexes citations, thereby enabling faster query responses and the ability to host citations involving publications lacking DOIs[2].

Open Access Tage 2021: valuable insights from the libraries in the German-speaking region 

On September 27, OpenCitations’ director Silvio Peroni, together with Niels Stern (DOAB/OAPEN) and James MacGregor (PKP), held the online workshop “How Open Infrastructure Benefits Libraries” during the Open Access Tage 2021. Open-Access-Tage (Open Access Days) are the annual central platform for the steadily growing Open Access and Open Science community from Germany, Austria and Switzerland, and are aimed at all those involved with the possibilities, conditions and perspectives of scientific publishing.  

The workshop gathered three of the SCOSS-supported infrastructures to discuss how Open Infrastructures (OIs) could encourage the engagement of university libraries, and how they could be beneficial game-changing alternative to commercial infrastructures. This theme, which was also been presented during the last LIBER conference, was here discussed under a new perspective, by involving the specific case of the libraries from the German-speaking region. Their point of view particularly emerged during the second part of the workshop, during which the participants were divided into two breakout rooms to discuss two questions each. These are the answers and comments that emerged from the discussions.  

1. What would prevent or encourage libraries in the German-speaking region to support open infrastructures? 

The three main concepts held to be crucial in this field were transparency, promotion and governance.  

Transparency: German libraries and public institutions often deal with strict funding limitations relating to donations. It is therefore crucial for OIs (a) to present in a clear way how libraries can get involved and the money needed, (b) to communicate what they do and how they can add value to libraries compared to other services, and (c) to clarify the direct return and benefits on investments. These points would make it easier to recommend OIs internally, especially when people from subject-specific institutions are interested in subject-independent OIs. Point (b) leads to the Promotion issue: Open Infrastructures should promote themselves non only on a global level, by communicating their impact in the open research movement as against non-transparent propitiatory services, but also at a local level, by providing information about the usage (and the value) of their services at an institutional and/or national level. This case-by-case narration (with attention to the specific benefits) would make it easier for the institutions to evaluate the sustainability of the investment. An incentive to donate is being actively involved in the community governance, i.e.through a board membership.  

Nevertheless, is also necessary for libraries to “take courage” when investing in such OIs, and, when possible, to overcome administrative boundaries by forming consortia. Finally, of particular note was a desire to see locally-managed sub-communities that could speak specifically to the German (or whichever) language environment, much as ORCID arranges itself.  

2. Community Governance. What kind of involvement do you want to see, how do you want to be involved? 

Some common problems which prevent the institutions from being involved are (a) a general concern about the fact that negotiations with publishers are typically the main focus of OA discussions – leaving little time to focus on OIs and other open initiatives, and (b) a lack of time, or of guidelines, for evaluating the different infrastructures to invest in. This is why SCOSS was appreciated as an intermediary in the decision process, because of its own rigorous evaluation and selection mechanismThe community-funding approach proposed by SCOSS thus seems to be the preferred way by which to support OIs.  

Regarding community governance, one idea could be to involve interested scholars in the governance of the open infrastructures (with the library acting as an interface between the open infrastructure and the scholars) rather than only involving library staff – although this idea was argued against in the second group, as researchers are often percieved as too busy to be functional in operational infrastructure groups. What also emerged from this second question is an interest in community involvement on different levels, for example as a community of practices or through discussion boards, mailing lists, periodic meet-ups, workshops, newsletters, etc. The community could also be articulated into local sub-communities, as in the successful case of ORCID and ORCID_DE.

California Digital Library invests in OpenCitations

OpenCitations is excited to announce that the California Digital Library (CDL) has joined our growing list of contributors.

CDL’s commitment to sustainable open scholarship has great value for the global scholarly community.  Through its investments and partnerships, CDL aims to create an international academic and librarian dialogue, trusting in the idea that “the university, its scholars and its libraries thrive when we transcend organizational boundaries and commit ourselves to shared investments”.

CDL’s contribution will generously support OpenCitations throughout 2021-2023. CDL funding in the fiscal year 2020-2021 also includes two other SCOSS-endorsed infrastructures, OAPEN and DOAB, the non-profit organization Open Access Switchboard, and the services PsyArXiv and SCOAP3 Books. As can be read in the recent post by Ellen Finnie, this investment reflects CDL’s “commitment to ’invest in open’ by allocating a portion of our collections funding to the development of open content and infrastructure in support of UC scholarship and teaching”.

OpenCitations team is grateful to be included in CDL’s ongoing investment in open infrastructure.  Thank you!
