The OGR ArcObjects driver provides read-only access to ArcObjects based datasources. Since it uses the ESRI SDK, it has the requirement of needing an ESRI license to run. Nevertheless, this also means that the driver has full knowledge of ESRI abstractions. Among these, you have:
Although it has not been extended to do this yet (there hasn't been a need), it can potentially also support the following GeoDatabase Abstractions
You can try those above and they may work - but they have not been tested. Note the abstractions above cannot be supported with the Open FileGeoDatabase API.
Prefix the Datasource with "AO:"
ogr2ogr -overwrite -skipfailures -f "PostgreSQL" PG:"host=myhost user=myuser dbname=mydb password=mypass" AO:"C:\somefolder\BigFileGDB.gdb" "MyFeatureClass"
ogrinfo -al AO:"C:\somefolder\PersonalGDB.mdb"
ogrinfo -al AO:"C:\somefolder\MySDEConnection.sde"
Read the GDAL Windows Building example for Plugins. You will find a similar section in nmake.opt for ArcObjects. After you are done, go to the $gdal_source_root\ogr\ogrsf_frmts\arcobjects folder and execute:
nmake /f makefile.vc plugin
nmake /f makefile.vc plugin-install
Date and blob fields have not been implemented. It is probably just a few lines of code, I just have not had time (or need) to do it.
