2023 has arrived, and it’s the time to put aside the old agendas and to fill the freshly printed organizers with new tasks. However, it is also worth looking back over the achievements of the past year.
So, before consigning 2022 to the archives, we want to take a moment to recall and celebrate all that OpenCitations has achieved over the past year, in terms of technical developments, community building, and our own internal organization.
Clarifying our objectives
Since its foundation, OpenCitations has been presented to the scholarly community as a infrastructure organization guided by the values of openness, equity and accessibility. In 2022, we publicly clarified our mission, our aims and our unique points by publishing these three documents:
In addition, we continued to monitor OpenCitations’ compliance with the Principles of Open Scholarly Infrastructure. Because one area in which we were still falling short involved stakeholder involvement in OpenCitations’ governance, in 2022 OpenCitations started reflecting on its organizational structure by creating a Governance Evolution Working Group. In addition, we explored the further development of our stakeholder community by establishing a parallel Community Building Working Group. These two small working groups, involving members of the OpenCitations International Advisory Board, will continue to meet throughout 2023 to develop strategic plans concerning OpenCitations open governance structure and outreach.
More people, more tools
In 2022, OpenCitations welcomed two new full-time developers to its team: Arianna Moretti as software developer, and Ivan Heibi as the person responsible for OpenCitations’ technical infrastructure. As of January 2023, the OpenCitations team consists of our two directors Silvio Peroni and David Shotton, our administrator and research manager Claudio Fabbri, myself as our communications director and community development manager, and our four developers: Giuseppe Grieco (software and systems developer), Arcangelo Massari (developer of OpenCitations Meta), Arianna Moretti (software and indexes developer), and Ivan Heibi (technical infrastructure manager). This team meets weekly at the Research Centre for Open Scholarly Metadata within the University of Bologna.
This enlarged technical workforce has been crucial in the development of the two new OpenCitations indexes, DOCI (citations from DataCite) and POCI (citations from PubMed), and our new database of bibliographic metadata, OpenCitations Meta, all of which were released in December 2022:
- DOCI, the OpenCitations Index of DataCite open DOI-to-DOI citations, is an RDF dataset containing details of all the citations that are specified in the most recent dump of DataCite metadata. The citations available in DOCI are treated as first-class data entities, with accompanying properties including the citations timespan, modelled according to the OpenCitations Data Model. Its first release (December 2022) contains information on 169,822,752 citations from 358,277 bibliographic resources.
- POCI, the OpenCitations Index of PubMed open PMID-to-PMID citations, is an RDF dataset containing details of all the citations from publications bearing PubMed Identifiers (PMIDs) to other PMID-identified publications, harvested from the National Institutes of Health Open Citations Collection (NIH-OCC). As for DOCI, the citations available in POCI are treated as first-class data entities, with accompanying properties including the citations timespan, modelled according to the OpenCitations Data Model. Its first release contains 717,654,703 citations from 26,024,862 bibliographic resources.
- OpenCitations Meta database stores and delivers bibliographic metadata for all the publications involved as citing or cited publications in the citations recorded in the OpenCitations Indexes. For each publication, the metadata exposed by OpenCitations Meta includes the publication’s title, type, venue (e.g. journal name), volume number, issue number, page numbers, publication date, and identifiers such as Digital Object Identifiers (DOIs) and PubMed Identifiers (PMIDs). In addition, OpenCitations Meta includes details of the main actors involved in the document’s publication, i.e., the names of the authors, editors, and publishers, each with its own additional metadata and identifier (e.g. ORCID). Its first release (December 2022) contains information on 87,321,593 bibliographic entities, 277,750,235 authors and 2,359,301 editors (counted by their roles, without disambiguating individuals), 710,226 publication venues, and 17,268 publishers.
As can be seen on OpenCitations roadmap, we have many tasks already scheduled for 2023, and for this reason OpenCitations team needs to expand further: we now seek applicants for a new Research Fellow position to work on the further development of the OpenCitations technical infrastructure from April 2023.
Our role in the community
Throughout 2022, the OpenCitations team has participated both online and in person in a number of international events, presenting details of OpenCitations to potential stakeholders and to Open Science experts, and connecting with similar organizations.
In October, OpenCitations organized our third workshop, the Workshop on Open Citations and Open Scholarly Metadata 2023, as a three-hour online event, to gather together and connect researchers, publishers and policy makers interested in the creation, reuse and improvement of open citation data and open scholarly metadata. The invited speakers provided a broad overview of the current state and future development of open bibliographic metadata and the scholarly record, and the role of OpenCitations in research assessment.
We have participated in two major European research and development project: In the context of the EC-funded project RISIS2 we released the new database OpenCitations Meta and the index DOCI, while within the OpenAIRE-Nexus project network we continue to provide open bibliographic citations as part of the open data components of OpenAIRE and the European Open Science Cloud. During 2022, the OpenAIRE team supported our activities in many areas, with a particular attention to communication and dissemination, as we explained in our blog post OpenCitations and EC funding: OpenAIRE Nexus and RISIS2.
The end of 2022 brought with it two new exciting collaborations that will be developed during the coming year: the inclusion of OpenCitations in the Jisc Collections, thereby permitting UK institutions to support OpenCitations through JISC; and our involvement in the GraspOS project (starting date January 1, 2023) as an open and trusted federated infrastructure for next-generation research metrics and indicators.
At OpenCitations we are deeply grateful to all our members and donors that have supported us financially so far, thus making it possible to enlarge our team, maintain our technical infrastructure, and work on our new data releases.
Much of our success has been due to our selection as an infrastructure worthy for inclusion in the SCOSS second pledging round in 2019. SCOSS helped us get in touch with a wider community, and enabled OpenCitations to have an increasingly significant role in the research environment. OpenCitations is now part of the SCOSS family, the community of all SCOSS-supported infrastructures, that provides a framework of mutual support for the the Infrastructures during their growth and a safety net should troubles occur along the path.
However, OpenCitations still has a long way to go along the path from being a sustainable open infrastructure to becoming a sustained open infrastructure providing reliable and invaluable services to our global stakeholder community. There are still 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 as our three-year period of SCOSS sponsorship draws to a close. All the information you may require to start helping us financially is available on the OpenCitations website: https://opencitations.net/membership.
2023 has just started. With your support, you can help us in making it an impactful year for OpenCitations and the Open Science community as a whole.
