The chapter presents the research theme Urban Archiving aming at to explore and prototype urban archiving practices generating intangible urban data, that is, urban data that potentially can give us insights and deeper understanding of urban matters and human behaviour. A series of research interventions are presented, conducted in the form of design activities and artistic actions or gestures. The process results in a collection of prototyped urban archiving practices. The tools and methods are developed together with the communities and artists we are collaborating with, and new tools and methods are continuously added.
