The document discusses open social mapping, which combines actor modeling, social network analysis, and crowdsourcing to map stakeholders in a system. It aims to center stakeholders by allowing them to map themselves, rather than relying on representative models. Potential benefits include increasing trust, identifying disconnects, visualizing diversity, and facilitating shared understanding between stakeholders. Examples of open social mapping projects in Canada are provided. Design considerations for open social mapping include engagement, data privacy, power dynamics, and ensuring interoperability between maps.
