The Grant Reuse and Abandoned Ideas Library (GRAIL) Preparatory Project will develop the governance, metadata, and community‑validation/foundation required for GRAIL to become a future EOSC Node. GRAIL addresses a structural gap in the Open Science landscape: the absence ofinfrastructure for preserving and reusing unexecuted research ideas, including rejected grant proposals, abandoned manuscripts, and “retirementreflection” documents. As recognized in our OSCARS evaluation (99/100), GRAIL represents “a rarely acknowledged yet fundamentally importantdimension of Open Science” by extending openness into the ideation phase and creating a new category of reusable scientific object.
During the six‑month Gravity project, we will produce all required preparatory outputs: the Project Plan (M1), the Project Charter and showcasepresentation (M4), and the EOSC Academy training matrix and use‑case report (M6). These will be developed through monthly Charter Workshops, structured interviews with researchers, and consultation with SSHOC, CESSDA, CLARIN, and EOSC technical liaison points to ensure full alignment with federation expectations and interoperability standards.
By formalizing legal, metadata, governance, and training structures, the project will deliver a community‑endorsed blueprint for a sustainable, horizontal EOSC Node. The resulting Charter will position GRAIL to enhance transparency, reduce research waste, and support cross‑disciplinary discovery and training across Europe.
The long-term scalability and sustainability of the GRAIL Node rest on its modular design, low operational footprint, and the Center for Trial and Error’s established experience sustaining open science activities through publication-related revenue and institutional grants from Utrecht University. These existing funding streams provide a stable baseline for maintaining core Node functions beyond the Gravity project period. Additional sustainability pathways will be explored during the preparatory phase, including support agreements with universities whose researchers make significant use of GRAIL, ensuring predictable operational resources while preserving openness and equitable access.
Scalability is enabled by GRAIL’s metadata-driven framework, which accommodates progressive expansion into new object types and disciplinary domains. While the initial focus is on rejected grant proposals, the Node is designed to incorporate abandoned manuscripts and “retirement reflection” white papers in a later phase. These novel research objects, highlighted during the OSCARS evaluation as innovative extensions of the open science paradigm, offer distinctive long-term value: abandoned manuscripts can support training, publication literacy, and method comparison, while retirement reflections preserve conceptual work that is typically lost when researchers leave the field.
Sustainability is further strengthened by GRAIL’s role as a horizontal infrastructure. As OSCARS reviewers noted, the Node demonstrates clear potential for cross-domain reuse and benefit to the “long tail” of science across disciplines, institutions, and research career stages, increasing the likelihood of diversified stakeholder engagement and future resource partners.
Finally, platform sustainability will be supported through the selection of an open-compatible, metadata-exposing repository environment during the preparatory phase. Rather than committing to a specific provider upfront, the project will evaluate systems meeting EOSC interoperability requirements, ensuring the GRAIL Node remains maintainable, adaptable, and aligned with evolving federation standards.
