HAL Open Science is a multidisciplinary open-access archive serving the scholarly community in France and internationally. It enables researchers to deposit preprints, postprints, theses, and data associated with publications from institutions such as the Centre national de la recherche scientifique, Université Paris-Saclay, and Institut national de la santé et de la recherche médicale. The platform interacts with national and international initiatives including European Open Science Cloud, CrossRef, and Directory of Open Access Journals to facilitate discoverability, citation, and preservation.

Overview

HAL provides an institutional and thematic repository infrastructure developed by the Centre pour la communication scientifique directe and operated in partnership with organizations like the Ministère de l'Enseignement supérieur, de la Recherche et de l'Innovation and major French universities. It supports deposit workflows compatible with mandates from funders such as the European Research Council, Agence nationale de la recherche, and Horizon 2020 programs. The archive integrates metadata standards aligned with Dublin Core, ORCID, and OpenAIRE to enable interoperability with services including Google Scholar, Scopus, and Web of Science.

History and Development

The repository initiative launched in the early 2000s amid debates involving stakeholders like the Budapest Open Access Initiative, Wellcome Trust, and proponents around the Public Library of Science. Development milestones include adoption by institutions including Université Grenoble Alpes, Sorbonne Université, and the École normale supérieure de Lyon, integration with identifier systems such as DOI registration agencies, and alignment with policy instruments like the Plan S coalition. Over time it expanded to include theses following collaborations with the Bibliothèque nationale de France and national consortia representing entities such as the Conférence des présidents d'université.

Functionality and Features

HAL's core functionality comprises submission modules for author self-archiving, institutional deposit mediations, and batch ingestion compatible with platforms like OpenAIRE and DataCite. Features include metadata enrichment using identifiers from ORCID and ISNI, full-text hosting with format support for PDF and XML, and export tools for citation managers such as Zotero and EndNote. Preservation and interoperability are supported via protocols such as OAI-PMH and integration with indexing services like BASE and HAL-Inria mirrors. Administrative functions permit institutions such as CNRS units and research centers like INRIA to manage collections, while compliance reporting assists applicants to funders like Horizon Europe.

Usage and Community

Researchers from organizations including Université de Strasbourg, Université de Lyon, Université de Bordeaux, and national laboratories like CEA use HAL to disseminate outputs ranging from articles and conference papers to technical reports and theses. The user community intersects with scholarly societies and publishers such as Editions Belin and cooperative infrastructures like Couperin.org and HAL-SHS portals for humanities and social sciences. Training and outreach are coordinated with library networks including the SUDOC union catalog and professional groups like the Association des Bibliothécaires de France to encourage deposit practices and linkages with identifier services such as ResearcherID.

Governance and Policy

Governance involves collaboration among the Centre national de la recherche scientifique, university consortia, and ministry stakeholders to set access, embargo, and licensing policies that relate to legal frameworks including Code de la propriété intellectuelle and funder mandates from entities like the European Commission. Policy instruments reference open licenses such as Creative Commons variants and align with national initiatives led by the Ministère de la Culture for heritage material. Institutional agreements facilitate partnerships with organizations like HAL-Inria and national libraries to ensure long-term stewardship and compliance with data protection rules overseen by authorities such as the Commission nationale de l'informatique et des libertés.

Impact and Criticism

HAL has influenced open scholarship practices among institutions including Université Paris 1 Panthéon-Sorbonne and research agencies like ANR, improving accessibility of outputs indexed by services like Google Scholar and Scopus. It supported shifts prompted by international advocacy from groups associated with SPARC and the Open Access Scholarly Publishers Association. Criticisms raised by stakeholders including some academic publishers and researchers at institutions such as Université de Lille concern versioning, metadata quality, and compliance with publisher embargoes; debates have referenced policy discussions at forums like CERN and assemblies of the European University Association. Ongoing responses include technical enhancements, expanded metadata validation, and collaborations with entities such as CrossRef and ORCID to address attribution and citation concerns.
