Agenda
What’s the interoperability problem;
what is “a CDB” and how does it solve the interoperability problem
Major CDB Use Cases:
Run-time format for high performance simulation and mission rehearsal systems
Refined source data repository for multiple external re-use
Current Status:
Vote in Tokyo TC meetings
3DIM DWG
Closing Plenary
Existing CDB documents were reformatted, with OGC copyright, and posted to Pending Documents

7. What is CDB?
Open, public-domain specification, based on broadly-used industry formats in folder/file structure (geotiff, JP2, shapefiles, OpenFlight, RGB, XML, etc.)
CDB is designed to support both runtime applications and source data storage needs
Optimized for rapid generation/update/deployment
CDB Specification first released on Nov 2005
CDB is a folder/file system convention that supports rapid access to non-proprietary file formats for concurrent use on multiple simulation systems
Enables simulation clients to modify the CDB at the data store in run time
In use today in the US, Canada, UK, Germany, Israel, Turkey, Australia, Singapore, Brunei
No relational database
File system direct access in Windows or Linux

CDB at OGC: status
CDB up to this point:
~20M USD from USSOCOM to develop and prove it works
~10 years of specification maturity “in the wild”
Several hundred run time simulation channel implementations from multiple vendors for worldwide simulation end-users
