This document supports the definition of: -  A Discrete Global Grid Systems (DGGS) core comprising: -  an RS using zonal identifiers with structured geometry, and -  functions providing import, export and topological query, -  Common spatio-temporal classes for geometry, topology, RS using zonal identifiers, zonal identifiers and zones, based on ISO 19111 CRS. The spatio-temporal scope is constrained to: -  spatial elements that are invariant through all time, and - temporal elements that are invariant across all space. -  Equal-Area Earth Reference Systems (EAERSs) for Equal-Area Earth DGGS.
