Section 5 CDB 2.0 - Background and History: Provides the background and history of CDB to provide the context for the CDB-X work described in this Engineering Report.
Section 6 CDB X Design Goals, Use Cases, and Conceptual/Logical Models: Documents any models, such as the OGC/ISO Simple Features geometry model, that are germane to the CDB-X work.
Section 7 Attribution in CDB-X: Section 7 discusses the Attribution Topic and the work and recommendations of the Attribution Subgroup.
Section 8 CDB Vector Data in Large GeoPackage Containers: Documents experiments to determine the viability of storing very large volumes of vector data in a smaller number of large GeoPackage files rather than a very large number of small Shapefiles.
Section 9 3D Models and Other 3D Content: Discusses the proposal to use glTF to encode and store 3D models in the CDB-XX data store
Section 10 CDB X Metadata and Integration: This section discusses metadata in CDB-X.
Section 11 Tiling and packaging of data layers: This section evaluates and discusses approaches to packaging one or more data layers in GeoPackages (including coverage, vector and 3D data) for CDB-X.
