- Redalyc/AmeliCA

Redalyc, based in Mexico and supported by the Autonomous University of the State of Mexico (UAEM), was established in 2003 as an Open Access journal index and article-hosting platform for scholarly Open Access journals published in Latin America, the Caribbean, Spain, and Portugal.  Redalyc includes journal quality assessment processes, full-text article hosting, automatic editorial workflow technology, metrics and author-level services. In 2018, Redalyc sought to expand its international scope. Currently, the infrastructure provides services to more than 1,400 Open Access peer-reviewed journals published by 670 institutions from 31 countries, including journals from Asia, Africa, and Europe. It provides access to more than 700,000 full-text articles in several different languages authored by 1.8 million authors from 150 countries.

AmeliCA is a multi-institutional community-driven initiative supported by UNESCO and led by Redalyc and CLACSO.  It fosters collaboration among different stakeholders, such as universities, journal editors, libraries, and the research community. AmeliCA’s driving force is its approach of science as a global public good to achieve more equitable and sustainable non-commercial scholarly communications through the respect of bibliodiversity and multilingualism that enables the academic community to lead, control, and own the lifecycle of knowledge production and communication.

Important information for SCOSS funders or donors.

SCOSS | Second Funding Cycle

Infrastructures from the 2nd pledging round: DOAB/OAPEN, PKP, and OpenCitations still need your support!

Directory of Open Access Books (DOAB) & Open Access Publishing Network (OAPEN)
SCOSS encourages you to support DOAB and OAPEN since they are closely interlinked and share the same goal to support the transition to OA books and to increase trust in OA book publishing.

- Directory of Open Access Books (DOAB) & Open Access Publishing Network (OAPEN)

DOAB is a digital directory of peer reviewed Open Access books and Open Access book publishers. The primary aim of the service is to increase discoverability of OA books so that they can reach a broader audience. DOAB harvests books’ metadata, which is used to maximise dissemination, visibility and impact. Aggregators can integrate this metadata into their commercial services while libraries can do the same into their online catalogues, making it easier for scholars and students to discover the works. The directory is open to all publishers of academic, peer reviewed books that are published Open Access and that meet academic standards. All publishers included in DOAB are screened for their peer review procedures and licensing policies.

While DOAB is a directory that provides links to OA books, the OAPEN Library is a repository of freely accessible academic books. OAPEN works with publishers and research funders to continue building a quality-controlled collection of Open Access books and provides services for publishers, libraries and research funders in the areas of deposit, quality assurance, metadata enhancement, dissemination and digital preservation.

- Public Knowledge Project (PKP)

The Public Knowledge Project (PKP) is a university research and development initiative that develops open source (free) software, provides support services and learning opportunities, and conducts research, all with an eye to improving the quality and reach of scholarly publishing. PKP is best known for creating and maintaining Open Journal Systems (OJS), one of the world’s leading journal publishing platforms, as well as Open Monograph Press and, soon, preprint server software.

OJS has been developed in close association with an international community of scholars, librarians, and software developers who turn to OJS for a professional quality publishing platform, and who contribute back to it with code, translations, and other support. OJS has evolved into a major contributor to open access (OA). To sustain PKP, it needs to build out and market its PKP Publishing Services, as this unit has shown the potential to be a reliable revenue source, capable of cross-subsidizing the development of open source software and infrastructure.

Whether your institution uses PKP software for faculty, student, and/or course journals, or not, SCOSS encourages you to support PKP’s efforts on behalf of open access. With more than 9,000 journals actively using OJS, this investment in PKP’s future, is a vital step in sustaining the growth of OA around the world.

- OpenCitations

OpenCitations is an independent infrastructure organisation for open scholarship dedicated to the publication of open bibliographic and citation data using Semantic Web (Linked Data) technologies. OpenCitations also undertakes related advocacy work, particularly as a founding member of the Initiative for Open Citations (I4OC). OpenCitations has the potential to give institutions and individuals the ability to analyse and reuse publication citations in library collections, other infrastructures and in research.

OpenCitations fully supports the founding principles of Open Science. It complies with the FAIR data principles proposed by Force11 that data should be findable, accessible, interoperable and re-usable, and it complies with the recommendations of I4OC that citation data in particular should be structured, separable and open. OpenCitations has published a formal definition of an open citation, and has launched a system for globally unique and persistent identifiers (PIDs) for bibliographic citations, the Open Citation Identifiers (OCIs), for which it maintains a resolution service.

OpenCitations has developed the OpenCitations Corpus OCC, a database of open downloadable bibliographic and citation data recorded in RDF.  The Corpus contains information on about 14 million citation links to over 7.5 million cited resources from a range of publishers. These are made freely available so that others may build upon, enhance and reuse them for any purpose, without restriction under copyright or database law.

In addition, OpenCitations is currently developing a number of linked data Open Citation Indexes using the information available in third-party bibliographic databases. The first and largest of these is COCI, the OpenCitations Index of Crossref open DOI-to-DOI citations, which currently contains information on more than 445 million citations.

OpenCitations also provides open source software of generic applicability for searching, browsing and providing APIs over RDF triplestores.

OpenCitations is innovating the way bibliographic and citation data are managed on several administrative and technical levels. OpenCitations provides, maintains and updates the OpenCitations Data Model which is based on its widely used SPAR (Semantic Publishing and Referencing) Ontologies. These can be used to encode all aspects of scholarly bibliographic and citation data in RDF, which enables them to be published as Linked Open Data (LOD).

- Directory of Open Access Journals (DOAJ)

DOAJ is primarily (but not only) a list of peer-reviewed open access journals covering all disciplines and more than 50 languages. Journals are listed after a detailed evaluation based on the application from journals/publishers. DOAJ receives around 500 applications per month. The rejection rate is around 50%. Evaluation is free of charge, like all other DOAJ services. DOAJ provides as well article metadata (currently 70% of journals upload article metadata) for download/harvesting. Currently, DOAJ lists nearly 9.400 journals and 2.500.000 article metadata records are available. The data DOAJ provides are harvested and downloaded with an API and integrated in all major discovery services, indexing databases etc.
