Research repositories contain a large amount of scientific knowledge, but access to structured articles and specialised information, such as datasets or software metadata, remains limited. In this paper, we present the INRIA DataLake project, which provides an ecosystem of scalable and interconnected pipelines for preparing scientific literature, extracting structured information, and applying specialised treatments. Using a large-scale shared infrastructure, Grid’5000/ABACA, we demonstrate our ecosystem through a concrete use case: extracting software mentions from scientific articles deposited daily and visualising them after validation in the HAL research portal. Our results show that the system can efficiently process large volumes of scientific literature while supporting user validation and interoperability with external systems. Designed to grow by integrating additional pipelines and sharing the preparation effort across research groups, this project already contributes to open science through improved visibility and tracking of research software.  \nKeywords: HAL · Open Science · Information Extraction · Digital Libraries · Software Mentions  \n1 Introduction  \nDigital repositories host a rapidly growing volume of scientific knowledge.

While traditional search systems support keywordbased retrieval, they do not provide access to structured data or to important research outputs, such as software, datasets, or experimental details. In recent years, open science policies have emphasised the need to better capture and measure research production beyond publications. For example, in France, the Open Science Monitor [3] reflects this evolution by aiming to quantify not only citation-based impact, but also the production of software and datasets. Achieving this objective requires scalable methods to extract structured information from large document collections.  \nData lakes have emerged as a dominant paradigm for storing and processing large volumes of heterogeneous data [9,4] . While classical data lake architectures defer transformation to the point of use, scientific literature processing benefits from early structured extraction—converting PDFs into machine-readable representations that downstream pipelines can consume without repeated parsing effort. Existing data lake solutions remain largely general-purpose and do not address these domain-specific needs, such as integration with scholarly repositories and open science infrastructures.  \nIn this paper, we present an ecosystem of generic, scalable, and interconnected pipelines for processing scholarly articles, extracting structured information, and enabling post-hoc analytics and insight generation.
