DESCRIPTION:Road infrastructure data held by French territorial authorities
  is rich\, authoritative and largely invisible to the open data ecosystem.
  This talk presents the journey of an active OSM and Wikidata contributor 
 who also works in road information management at municipal\, intermunicipa
 l and departmental levels in Southern France. This dual role has led to th
 e design of a coherent\, nested open data architecture for road intelligen
 ce.\nAt the core lies a data model in which Wikidata acts as the geometric
  abstraction layer enabling convergence of non-official data sources and m
 ulti-database identifiers — its design encouraging exhaustiveness throug
 h sourced statements and a completeness gauge that makes quality progress 
 both visible and rewarding. OpenStreetMap holds the geometric and operatio
 nal details\, while BD TOPO (IGN) serves as the authoritative reference da
 taset to which both OSM geometries and Wikidata items are systematically c
 ross-referenced and linked. This nesting creates a powerful convergence: t
 he State's national reference\, locally produced data from territorial aut
 horities\, and their near real-time mirroring through OSM geometry and Wik
 idata semantics.\nPanoramax street-level imagery feeds both OSM mapping ta
 sks and change detection workflows — including early experiments with AI
 -assisted approaches applied to infrastructure monitoring. The presentatio
 n covers modelling choices at the Wikidata–OSM interface\, automation pi
 pelines that reduce friction between internal road management tools and op
 en data outputs\, and practical benefits for road users across GPS and nav
 igation applications.\nThis talk targets contributors interested in Wikida
 ta–OSM integration\, open government data processes\, and the practical 
 use of street-level imagery for infrastructure maintenance. It will also o
 penly address methodological limits\, work organization practices\, and cu
 rrent gaps in tools within and around the OpenStreetMap ecosystem — incl
 uding possible ways forward\, and an honest look at tensions between the p
 ace of field experimentation and the deliberative nature of community cons
 ensus.
