References inside to other ontologies will be included.
A handle to the model will be returned, or 0 in case something went wrong.

public const string EngineDLL = @"engine.dll";[DllImport(EngineDLL, EntryPoint = "OpenModelW")]
public static extern Int64 OpenModelW(string fileName);

[DllImport(EngineDLL, EntryPoint = "OpenModelW")]
public static extern Int64 OpenModelW(byte[] fileName);

Property fileName

Size: 64 bit / 8 byte (reference)
The file name of the file as available in the file system in Unicode (wchar_t *). The given wchar_t array will not be adjusted. The size of each wchar_t element is depending on the OS, both 16 bit / 2 bytes wchar_t elements as well as 32 bit / 4 byte wchar_t elements are recognized and supported.
