Summary: CollectieveKracht.eu constitutes an important complementary research infrastructure for CoCon. Developed as the leading European knowledge exchange platform for citizen collectives, it combines a longitudinal database of contemporary collective initiatives with a collaborative digital environment in which researchers and practitioners jointly generate, validate and interpret knowledge. Rather than functioning solely as a repository of data, CollectieveKracht provides an interactive infrastructure for continuous knowledge production, enabling the systematic collection of organisational, institutional and governance information across hundreds of citizen collectives while simultaneously facilitating comparative analyses, stakeholder feedback and knowledge exchange. The platform currently connects more than 550 citizen collectives across sectors such as energy, housing, care, food and sustainability, thereby offering a unique contemporary laboratory for studying institutions for collective action.  

A distinctive feature of CollectieveKracht is that it is built on the principles of Extreme Citizen Science. Unlike conventional citizen science initiatives, which typically involve participants primarily in data collection, Extreme Citizen Science actively involves citizens throughout the entire research cycle—from identifying research questions and designing research, to interpreting findings and co-developing practical solutions. This creates a continuous process of mutual learning between researchers and practitioners, ensuring that scientific knowledge and practical experience inform one another throughout the project. The platform therefore functions simultaneously as a research infrastructure, a knowledge exchange environment and a participatory scientific ecosystem, embodying Open Science and FAIR principles while fostering long-term collaboration between academia and society.  

Relevance to CoCon: CollectieveKracht.eu, and its international counterpart CollectivePower.eu, constitute key components of the research infrastructure supporting CoCon. CollectieveKracht has been developed as the leading European knowledge exchange platform for citizen collectives, combining a longitudinal database of contemporary collective initiatives with a collaborative digital environment in which researchers and practitioners jointly generate, validate and interpret knowledge. Rather than functioning solely as a repository of data, the platform provides an interactive infrastructure for continuous knowledge production, enabling the systematic collection of organisational, institutional and governance information while facilitating comparative analyses, stakeholder feedback and knowledge exchange. 

A distinctive feature of the platform is that it is built on the principles of Extreme Citizen Science, which actively involves citizens and practitioners throughout the research process—from identifying research questions and contributing data, to interpreting findings, validating results and co-developing new knowledge. This participatory approach transforms the platform into a living research infrastructure in which scientific inquiry and societal practice continuously inform one another, fully consistent with the principles of Open Science and FAIR data stewardship. 

Within CoCon, the international platform CollectivePower.eu will support the project’s European rollout by providing the digital infrastructure for collaboration with institutions for collective action across countries. In particular, it will facilitate participatory archiving, enabling contemporary institutions, local historians, archivists and citizen researchers to identify, document, digitise and contextualise historical governance documents, statutes and organisational records that would otherwise remain inaccessible. This participatory infrastructure substantially expands CoCon’s capacity to discover and preserve institutional sources while ensuring that archival reconstruction itself becomes a collaborative scientific endeavour. Together, CommonRules, the Longitudinal Institutional Grammar (L-IG), and CollectieveKracht/CollectivePower create a unique integrated research infrastructure that connects historical reconstruction, contemporary observation and participatory knowledge production across the Cooperative Continuum. 

Summary: Developed a unique dataset applying Institutional Grammar to the formal rules of a large contemporary mutual insurance organisation (Smart), translating complex governance rules into structured, machine-readable data suitable for computational analysis. 

Relevance to CoCon: This dataset demonstrates Tine De Moor’s pioneering work at the intersection of institutional theory and computational social science. By operationalising governance rules for systematic comparison, it directly supports CoCon’s ambition to develop AI-supported methods for analysing citizen collectives and strengthens the project’s research infrastructure for comparative institutional analysis. 

Summary: Developed and openly shared a large historical dataset of Amsterdam marriage banns, creating a valuable resource for research on demographic behaviour, migration, and long-term societal change. 

Relevance to CoCon: Although not directly focused on institutions for collective action, this dataset showcases Tine De Moor’s leadership in creating high-quality FAIR historical research infrastructures. It demonstrates expertise in large-scale data curation, interoperability, and open science -in particular the use of Citzen Science Principles- that directly supports CoCon’s ambitions for sustainable European research infrastructures. 

Summary: Developed one of the world’s first large-scale databases systematically documenting and coding the governance rules of historical commons across Europe using Institutional Grammar, enabling computational comparison of institutional design across centuries. 

Relevance to CoCon: This database is one of Tine De Moor’s most innovative scientific contributions and forms a direct methodological foundation for CoCon. It transforms qualitative governance rules into machine-readable data, enabling AI-supported comparative analyses of institutions for collective action. The database exemplifies CoCon’s vision of combining historical research, digital humanities, computational methods, and FAIR data to identify the institutional principles underpinning resilient citizen collectives. 

Summary: Developed an internationally unique collection of harmonised open-access datasets covering multiple forms of institutions for collective action across Europe and beyond, including commons, guilds, waterboards, beguinages, and journeymen’s associations. 

Relevance to CoCon: These datasets constitute one of the world’s most comprehensive comparative research infrastructures on institutions for collective action. They demonstrate Tine De Moor’s pioneering role in developing interoperable historical databases that enable systematic comparison across institutional types, countries, and historical periods. Together, they provide the historical backbone for CoCon’s comparative research strategy and the CollectivePower platform. 

Summary: Co-developed an innovative digital tool for validating genealogical data through automated quality control, substantially improving the reliability and reproducibility of large-scale historical demographic datasets. 

Relevance to CoCon: Treechecker illustrates Tine De Moor’s long-standing commitment to methodological innovation and digital research infrastructure development. By creating automated tools that improve data quality and facilitate large-scale collaborative research, it exemplifies the digital, FAIR, and computational approach that underpins CoCon’s ambition to build next-generation research infrastructures for institutions for collective action.
