Description:	CDB Version 2.0 is a major revision to the CDB Standard. The CDB Version 2.0: Core Standard specifies requirements (rules) defining a standardized model and structure for a single, versionable, virtual representation of the earth. The full CDB Standard is comprised of a fundamental core, Parts (extensions to the core), and profiles. The core consists of a suite of mandatory and optional requirements classes and conformance classes that are components in any extension, profile, and implementation. Core requirements can be profiled (restricted). An overarching design principle is that a CDB data store is focused on the ability to store, manage, and access extremely large volumes of geographic content and related assets such as model definitions in as deterministic manner as possible. A CDB compliant structured data store provides a geospatial content and model repository that is plug-and-play interoperable between applications within a domain and potentially between domains. In the CDB context, a domain represents an information community, such as gaming, tactical analysis, or simulation, that has a common set of requirements for data content including access.
