I’m currently working with ESRI GDB datasets and I can easily open hierarchical geodatabases and walk the tree using the API that gdal provides.

root_group = ds.GetRootGroup()

for g in root_group.GetGroupNames()
    subgroup = root_group.OpenGroup(g)
    layers = subgroup.GetVectorLayerNames()

    for l in layers:
        ...

Now I need to create such hierarchy in a GDB dataset myself but I can’t find anything useful in the documentation. Is it possible to create groups and assign layers to them in gdal / ogr?

Any help is appreciated.
