Hi Haggi, can I suggest to look at this code snippet:

https://github.com/appleseedhq/appleseed/blob/18f4ef9f992966b990b674abc40cc61a696082b5/sandbox/samples/cpp/alembicassembly/alembicassembly.cpp#L241

It's exactly what you need. Roughtly:

Alembic::AbcCoreFactory::IFactory factory;
Alembic::AbcCoreFactory::IFactory::CoreType core_type;

Alembic::Abc::IArchive archive = factory.getArchive(file_path, core_type);

switch (core_type)
{
   case Alembic::AbcCoreFactory::IFactory::kHDF5:
       RENDERER_LOG_INFO("        core type: HDF5");
       break;
   case Alembic::AbcCoreFactory::IFactory::kOgawa:
       RENDERER_LOG_INFO("        core type: Ogawa");
       break;
   case Alembic::AbcCoreFactory::IFactory::kLayer:
       RENDERER_LOG_INFO("        core type: Layer");
       break;
   case Alembic::AbcCoreFactory::IFactory::kUnknown:
       RENDERER_LOG_WARNING("        core type: Unknown");
       break;
   assert_otherwise;

}

Hope this helps. :)

Hi

There is a utility:

abcls -m alembic.abc

out:

Using Alembic 1.7.8 (built Aug  6 2018 19:43:11)
  (file doesn't have any ArchiveInfo)
  core type : HDF5
