One of OntoCommons' primary objectives is to foster collaboration with relevant initiatives and organizations, aiming to create synergies and promote integration. Key partners include the European Open Science Cloud (EOSC), EU projects, the Research Data Alliance (RDA), and the FAIR communities. Integration of ontologies with infrastructures is vital to facilitate actionable and valuable resources.
Data infrastructures have evolved into essential services for researchers and data professionals, necessitating adaptations not only in technical aspects but also in organizational structures. (Millerand & Baker, 2020).
To engage effectively with the EOSC, EU projects, RDA, and FAIR communities, OntoCommons has established a Knowledge Exchange Space for Data Management and Documentation (KExS). This space hosts a series of workshops and meetings attended by OntoCommons members and representatives from various related projects and initiatives. The document offers insights into the work undertaken in Task 1.4, which aims to foster close cooperation with infrastructures via EOSC and related initiatives. The EOSC landscape is dynamic, with numerous organizations and research teams striving to define and develop services and policies that meet the needs of research communities and industries. Through KExS events, participation in relevant gatherings, interactions with stakeholders, and engagement with OntoCommons' own stakeholders, strong and enduring
connections within this network have been established. 
In this deliverable, we report the activities of the task during the reporting period, namely the continuation of our networking activities within the KExS, the organisation of workshops and Jour Fixe to raise the awareness within and outside the project. We provide insights into additional relevant projects and a short update of the Strategic Research and Innovation Agenda (SRIA) in the context of European Data Infrastructures, and explain the European Data Spaces efforts and how they relate to OntoCommons. The document also provides a glimpse of future developments concerning EOSC Nodes.
All these are players are to contribute to the building an infrastructure of services for data provisioning and creation. The material modelling domain will profit from these developments, given that contact with communities working on the data infrastructure components has been established during the OntoCommons project’s life.
