4th workshop on FAIR Urban Drainage Data

Join us for the 4th workshop on FAIR Urban Drainage Data, where we will share recent advances on semantic data models, collaborative work on shared vocabularies, and sharing data from:

  • Sewer water levels and flows
  • Urban flood models
  • CSO spill data
  • Water quality

Date : 15.07.2025 -12:00 to 13:00 (CEST) ONLINE

Key topics include: 

  • Ontology development: We discuss ongoing efforts of a shared semantic framework for urban drainage data. Based on existing glossaries and ontologies (e.g., Dutch Urban Water Ontology GWSW, VSA, SOSA/SSN, OGC), this work defines a base from which LLM agents can transform data (e.g., CSV, NetCDF) into harmonized knowledge graphs.We focus on semantic structure, and AI applications to build interfaces that interpret and visualize the data.

  • Collaborative workflows: Following a participatory approach, working groups evaluate and vote on variable names, contributing to the first draft of a data model. The resulting draft documentation is managed openly (e.g., GitHub) and will support a first publication.

  • Community engagement and upcoming conference:
    We invite participants to share datasets with us, which can be redirect to the appropriate subgroup we have formed. We also welcome inputs on UDS observation parameters and metadata standards.
    We will present the findings of the workshop series at the Urban Drainage Modelling (UDM) conference [Monday, September 15. 15:00 – 16:00]

Whether you are interested in leveraging FAIR data for innovative machine learning applications or ensuring regulatory compliance, this initiative of the IWGDM offers a collaborative platform to define future directions in urban drainage data sharing. We invite researchers, industry professionals, and public decision-makers to join us in shaping the future of urban water management.
