This article examines the activities and developments surrounding the public release of Map XML data in Japan, particularly the voluntary initiative. To address data distribution and file format challenges, the "Adopt Map XML Project (amx-project)" was launched on GitHub in January 2023. Their primary endeavor was to redistribute all data, providing an easier bulk download interface. Many tools and web map viewers emerged in the week following the public release, allowing users to visualize and utilize the data. The amx-project used GitHub's open platform to continuously discuss its direction and technical considerations. While amx-project operates voluntarily without adopting traditional project management, its role in sharing the potential and challenges of spatial data, exploring opensource technologies, and serving as a community hub for digital map developers and users is crucial.
