The Social Sciences and Humanities Open Marketplace (SSHOMP) - marketplace.sshopencloud.eu/ -, one of the flagship services of the “Social Sciences and Humanities Open Cluster” (SSHOC), is a discovery platform for new and contextualised resources from the Social Sciences and Humanities (SSH) [1, 2]. Its main aim is to support researchers in discovering, accessing and comparing digital tools and methods for their research. With its five content types - Tools & Services, Datasets, Training Materials, Publications, and Workflows - the SSHOMP covers a large range of research practices and methodological approaches.

The SSHOMP is built on three interrelated pillars: community, curation and contextualisation. This poster focuses on the community dimension, in line with the theme of the DARIAH Annual Event 2026. It presents the various roles and uses of the SSHOMP and illustrates what it means to be a contributor to this collaborative service (especially, based on some user stories), and how the content is moderated and the community is engaged by the Editorial Team running the portal [e.g., 3].

Participatory projects in the digital humanities have demonstrated their potential to empower academics and enable shared ownership of knowledge infrastructures. The SSH OMP builds on this insight by supporting the collaborative creation of tools and methods descriptions. While it is not directed at society at large, the SSHOMP nevertheless embodies a form of generous thinking that values openness and inclusivity in the way a collective truth about the tools and methods is built and promoted.

Community engagement is further supported through features such as curated collections - under development at the time of writing this abstract - which bring together resources around shared research questions, methods or disciplinary perspectives. The poster highlights recent work on collections developed in national or project-based communities - such as the Text+ in Germany or the ATRIUM project community for example. These activities demonstrate how local or disciplinary practices are integrated into a broader European research infrastructure landscape and how the SSHOMP functions as an infrastructure of engagement [3], which content is shaped by the communities.

From a more technical and conceptual perspective, the poster also highlights how the SSH Open Marketplace has been designed as a service based on community needs, and demonstrates how the team in charge of the service, always keen on collecting ideas for new features to be implemented, actively engages with its communities to ensure that the SSHOMP fits their needs. That is also why this poster is an interactive poster that asks a series of core questions to the participants in order to: 1/collect ideas for new and unforeseen uses of the Marketplace, 2/identify new tools or collections to be created and indexed in the Marketplace, 3/collect suggestions for new features to be implemented in future upgrade of the service. Thanks to sticky notes and pens available next to the poster, participants to the DARIAH Annual Event will be asked to contribute their views on what the SSHOMP should include and look like.
