Tag: Open Access Publishing

Open access (OA) publishing has transformed scholarly communication by removing paywalls and enabling free, immediate online access to research. Under the OA model, users can read, download, copy, distribute, print, search, link to, or use full texts for any lawful purpose without financial, legal, or technical barriers beyond an internet connection. This movement, formalized in the 2002 Budapest Open Access Initiative, addresses the limitations of traditional subscription-based publishing, where high costs restrict access, particularly in developing countries and underfunded institutions.

Today, OA is no longer optional for many researchers. Global funders, governments, and institutions increasingly mandate it to accelerate scientific progress, boost citations, promote equity, and ensure public accountability for publicly funded work. As of 2026, over 70% of new peer-reviewed articles in some fields are published OA, driven by policies emphasizing immediacy—no embargoes—and open licensing (typically Creative Commons Attribution, or CC BY).

OA comes in several flavors. Gold OA involves publishing directly in fully open journals or platforms, often with article processing charges (APCs) paid by authors, funders, or institutions. Green OA allows self-archiving of the accepted manuscript or version of record in a public repository, usually without fees. Diamond OA (also called platinum) is free for both authors and readers, supported by institutions, societies, or consortia. Hybrid OA combines subscription and OA options within the same journal but is increasingly discouraged by major funders.

The shift brings clear benefits: faster knowledge dissemination, greater collaboration, and higher research impact. Yet it also poses challenges—APC affordability, journal quality concerns, and compliance complexity. This article explains the major policies shaping OA in 2026, with a focus on Plan S, HINARI (part of Research4Life), and broader mandates, while outlining practical compliance steps. It also shows how platforms like IndraStra Global’s tools simplify adherence.

Plan S: The Push for Immediate and Equitable Open Access

Launched in September 2018 by cOAlition S—a consortium of research funders and organizations—Plan S remains a cornerstone of the OA revolution. Its core principle is simple yet transformative: scholarly publications from publicly or privately funded research must be made full and immediate Open Access upon publication, with no embargo periods.

By 2026, Plan S compliance is mandatory for all cOAlition S members (including national funders in Europe, the Wellcome Trust, and others). The 2026–2030 strategy, announced in November 2025, reaffirms this commitment while expanding to sustainable infrastructure and equitable models. Transformative agreements (which flipped hybrid journals to OA) lost funder support after December 2024, signaling a clear move away from hybrid publishing.Compliance routes under Plan S are straightforward:

1. Publish in a fully OA journal or platform that meets technical and quality standards.
2. Use an OA publishing platform.
3. Deposit the Version of Record (VoR) or Author Accepted Manuscript (AAM) in an OA repository immediately (no embargo) under a CC BY license (or equivalent).

Authors must retain sufficient rights, and funders generally prohibit APCs in hybrid journals. The Journal Checker Tool helps researchers verify compatibility.

Plan S has global ripple effects. It influenced policies worldwide, pressuring publishers to adapt and accelerating the growth of Diamond OA models. Critics once worried about APC inflation or reduced publishing options, but data shows increased OA uptake without major quality drops. For institutions and publishers, the emphasis on repositories as a compliant route has boosted infrastructure investments.

HINARI and Research4Life: Bridging the Global Access Divide

While Plan S targets immediacy for funded research, HINARI (Health InterNetwork Access to Research Initiative) addresses equity for the developing world. Launched in 2002 by the World Health Organization and six major publishers, HINARI is one of four programs under the Research4Life partnership (alongside AGORA for agriculture, OARE for environment, and GOALI for law).

As of April 2026, Research4Life provides free or low-cost access to tens of thousands of peer-reviewed journals, books, and databases for eligible not-for-profit institutions in over 120 countries. Group A (low-income) nations receive free access; Group B (lower-middle-income) pay a small fee. Refugee camps also qualify regardless of location.

HINARI is not a strict OA mandate but complements global OA efforts. Many publishers automatically waive or discount APCs for corresponding authors from HINARI-eligible countries in Gold OA journals. This aligns with broader equity goals: publicly funded research in high-income nations becomes accessible where resources are scarce, while authors from the Global South face fewer financial barriers to publishing OA.

Participation is voluntary for publishers, but alignment with OA principles strengthens their offerings. Institutions register directly via Research4Life to gain access, and the program includes training on research skills and publishing. In 2026, HINARI continues to demonstrate how targeted access initiatives reduce the knowledge gap, supporting Sustainable Development Goals in health and beyond.

Broader Open-Access Mandates in 2026

Plan S and HINARI operate alongside a web of national and regional policies:

• European Union / Horizon Europe: OA is legally required for all peer-reviewed publications from funded projects. Immediate access via trusted repositories or platforms like Open Research Europe (expanding in autumn 2026 with collective funding from 11 countries) is mandatory. No embargoes; data management plans are also required under FAIR principles (Findable, Accessible, Interoperable, Reusable).
• UKRI (United Kingdom Research and Innovation): Immediate OA via journal or repository deposit, with no embargo. Transformative journal funding ended in January 2025. Monographs and books have a 12-month embargo allowance in some cases.
• United States (NIH, OSTP-influenced agencies): The 2024 NIH Public Access Policy (effective for manuscripts accepted after July 2025) requires immediate deposit in PubMed Central upon acceptance/publication—no embargo. Broader federal OSTP guidance has pushed similar zero-embargo rules across agencies.

These mandates converge on key requirements: immediate availability, open licensing, and repository use as a reliable compliance path. Many now extend to preprints, data, and code, emphasizing transparency.

Compliance Requirements and Common Challenges

Compliance typically involves:

• Choosing compliant venues (use tools like the Journal Checker Tool or Open Policy Finder).
• Securing rights retention (e.g., via funder-approved language in submission agreements).
• Depositing in approved repositories with proper metadata (DOI, ORCID, funding acknowledgments).
• Applying CC BY (or equivalent) licenses.
• Paying APCs only where permitted and budgeted.

Challenges persist: tracking multiple funder rules, navigating APC costs (mitigated by waivers and institutional deals), ensuring repository interoperability, and maintaining version control. Non-compliance can delay funding or affect career evaluations. Institutions often provide guidance offices or block grants to ease the burden.

How IndraStra Global Platforms Support Compliance

Platforms built for OA make adherence seamless. IndraStra Global’s solutions exemplify this integration.

The IndraStra Open Journal Systems (OJS) 3.5.0-4 (updated April 2026) enables institutions and societies to host fully compliant OA journals. OJS supports Gold and Diamond models, automated metadata export, DOAJ indexing, and CC licensing—ideal for Plan S Route 1 or Horizon Europe requirements. Publishers can manage peer review, APC waivers for HINARI-eligible authors, and immediate public access without technical hurdles.

For Green OA and repository mandates, IndraStra Global Open Repository (IGOR)—powered by Zenodo—offers a robust, OAI-PMH-enabled archive. Registered in ROAR (ID 13459) and OpenDOAR (ID 4429), IGOR allows immediate deposit of articles, preprints, datasets, and more (up to 50 GB). It supports non-proprietary formats, version control, long-term preservation, and search-engine optimization. Deposits automatically enter the IGOR community collection, ensuring discoverability and compliance with Plan S repository routes, NIH PMC-style requirements, and EU trusted-repository standards. IGOR’s Zenodo foundation guarantees persistent identifiers, FAIR alignment, and rights retention tools.

Institutions using IndraStra’s broader knowledge infrastructure (including DSpace expertise for custom repositories) can create interoperable ecosystems that automatically generate compliant metadata, enforce licensing, and track funder mandates—reducing administrative load while meeting 2026 global standards.

Conclusion

Open access publishing is now the default expectation rather than an ideal. Policies like Plan S enforce immediacy and equity, HINARI bridges global divides, and mandates from the EU, UK, and US demand actionable compliance. The result is a more open, collaborative research ecosystem.

For researchers, publishers, and institutions, the key is proactive planning: select compliant venues early, leverage repositories, and partner with purpose-built platforms. IndraStra Global’s OJS and IGOR tools exemplify how technology turns policy requirements into straightforward workflows—ensuring your work reaches the widest audience while satisfying funders and advancing open knowledge.

In an era of rapid scientific challenges, OA is not just about access—it is about accelerating discovery for all. Platforms committed to these standards, like those offered by IndraStra Global, make that vision practical and sustainable.
