CLARIAH-VL(+) Open Humanities Service Infrastructure: FAIR, open, and reusable tools & services for Digital Humanities research

CLARIAH-VL(+) is the Flemish contribution to the European research infrastructures CLARIN and DARIAH, supporting digitally enabled research in the Arts and Humanities. Funded by the Research Foundation Flanders (FWO) since 2021, CLARIAH-VL has developed - and still sustains in the current CLARIAH-VL+ project phase - a portfolio of various digital tools and services, designed to support research workflows in the Humanities (and sometimes beyond), from data creation and enrichment to analysis and dissemination.

In this poster, we want to present an overview of the current CLARIAH-VL tools and services, explicitly framed within the principles of Open Science. Almost all of these tools are developed and distributed as Open Source research software. Where applicable, associated datasets are published with licenses that are as open as possible, enabling reuse, redistribution, and long-term sustainability. Particular attention is paid to compliance with the FAIR principles for research data and software, including persistent identifiers, rich metadata, interoperable standards, and clear licensing.

The CLARIAH-VL service portfolio includes, among others, tools for Named Entity Linking (LATTE), collaborative XML editing (Axolotl), stylistic and topical analysis (Styloscope & Toposcope), PoS-tagging modules for Dutch, English, French and German (Fullstop & Lettuce) and Machine Translation evaluation (MATEO). These services are designed to be modular and interoperable, allowing integration into broader research workflows and infrastructures at both national and European levels. Several tools are accessible through user-friendly web interfaces, while others can be deployed as reusable components in customized research pipelines.

By showcasing the CLARIAH-VL tools and services as a coherent Open Science infrastructure, with this poster we would like to demonstrate how Digital Humanities research can benefit from open, FAIR-by-design research software and data. The CLARIAH-VL approach illustrates how infrastructural investments can translate Open Science principles into concrete, sustainable research practices that foster transparency, reproducibility, and reuse across disciplines.
