From the author:

It implements Oledb simple provider and allows to use ADO components with Geomedia connections(data servers). The provider has to be registered running the GmDataComponent.reg file. VB will register the GmData command. The test project is GmDatasrc. It needs UsSampleData.mdb in D:\Warehouses\examples
