Open-AudIT enables a CMDB - import to another or use Open-AudIT directly, the choice is yours. It's your data, afterall.
Open-AudIT can be used as your CMDB or as the data source for another application.
As at v2.0, Open-AudIT supports a complete JSON restful API.
Define a query and have your external program call the API and retrieve the data.
