How to retrieving global and local component names from AEC styles

[tbrammer]

I'm developing an ARX using OMF on plain AutoCAD (not Architecture).

To query the component names of door- and window-styles I use the OMF API:

  AecDbDictRecord::getMaterialComponents(

          AcGeIntArray& ids,

          AecRmCStringArray& compNames,

          AcDbObjectIdArray& materialIds

  );

On German and English AutoCAD versions getMaterialComponents() returns different compNames for the same style in the same DWG:

    compNames (doors)       compNames (windows)

ids German    English       German         English

1   Rahmen    Frame         Rahmen         Frame

2   Türstock  ?             Fensterflügel  ?

3   Füllung   Panel         Glas           Glass

4   Glas      Glass         Sprossen       ?

5   Sprossen  ?             -              -

So obviously I get “localized UI-names” in compNames. Are there “local” and “global” names stored in the DWG?

How can I retrieve the “global” names? I have to make sure that I get the same names on every language version of AutoCAD.

Note: My test DWG also contains a wall style with additional components. For this style getMaterialComponents() returns the same (German) component names in both AutoCAD language versions. But here I get totally different values for ids:

ids     German/English

101         Außen

103         Innen
