The project “Legal Ontologies and Knowledge Graphs – Open Source Resources” emerges from the realization that the absence of a standardized data format and interface poses a significant challenge in connecting diverse sources of legal data and associated tools. With each vendor defining its own data model, the lack of a cohesive standard impedes the seamless connection of tools, hindering the creation of a COMMON LEGAL PLATFORM. However, the Liquid Legal Institute recognizes the potential for collective collaboration to address this issue. By working collaboratively on a state-of-the-art overview, the project seeks to benefit everyone involved. The initial focus is on creating an overview, paving the way for subsequent projects to delve into the combination and interconnection of data points. The repository is openly published, allowing universal access without restrictions, and contributions from various experts in Knowledge Engineering, spanning commercial, non-profit, academic, and public sectors, are welcomed. The ultimate goal is to generate a comprehensive overview of relevant resources and share them freely with the wider community.
