Context

Water is central to many pressing societal issues. Examples include droughts, floods, and contaminated drinking water, all of which require knowledge of the relationships between surface water and groundwater features. These are just some of the cases where the intersection of watersheds and aquifers and the proximity of water wells and river gauges are key elements in planning for and responding to major events. Linked Open Data (LOD) technologies provide an effective new way to represent, find and access these relationships and features. This workshop will develop a linked data architecture for Canadian hydro data that will be tested in the GSIP pilot project and serve as a Canadian starting-point for a similar pilot spanning the CAN-US border. The workshop will be informal and consist of detailed technical discussions on key topics, with the intended goal of developing an architecture and workplan to enable subsequent implementation by participants.

Objectives

  • Develop uses-cases and a draft architecture for GSIP
  • Develop knowledge and workplan for implementation of the architecture

Expected Outputs

  • Meeting notes
  • Draft Architecture report with use-cases
