 The minimum information about geospatial information system, MIARGIS, standard was developed to provide a framework for publicly sharing geospatial information system, GIS, datasets. It follows the fair principles and provides a directory structure and a JSON metadata format to capture important metadata about GIS layers and maps. Additionally, it allows users to extract metadata from Esri JSON and Geodson formats, as well as customized JSON files. This standard can be used to create a repository for GIS datasets, which would benefit the wider GIS community. This article was authored by P. Travis Thompson, Swayta Oja, Christian D.
