Significant progress was achieved as part of a number of initiatives including:

- several OGC Testbeds,
- the OGC Vector Tiles Pilots,
- the Releasable Basemap Tiles Code Sprint,
- the Ecere GeoConnections 2020-2021 project entitled "Flexible real-time data processing and visualization workflows emerging from OGC API modules" ("Modular OGC API Workflows" a.k.a "MOAW"), and
- the Ecere GeoConnections 2025-2027 project entitled "Advancing and Implementing OGC Standards for GeoDataCubes, DGGSs, Data Stores for Digital Twins and Cartographic Symbology").

Special thanks to Maxime Collombin, Olivier Ertz and Erwan Bocher for their support and collaboration in the context of the Cartographic Symbology Standard Working Group.
