pgio is the Planning Graph Data Model Specification. pgio aims to integrate all information related to building and planning into an easy to understand model that can be encoded in a wide range of formats, such as GeoPackage, GeoJSON and Simple Feature GML (SF-2). It re-uses codelists and concepts from applicable, well-established standards such as NAS (ALKIS), XPlanGML, and CityGML.
Initially, there is only a GML 3.2.1 Application Schema (pgio.xsd) available in this repository. This schema can be used to create and validate GML-encoded pgio data sets.
