A product file can contain templates, that were originally instatiated from a dictionary (e.g. bSDD). These template should stay linked to the "source of truth" in the dictionary.
The most elements in IFC have a attribute with the name "GlobalId", e.g.
GlobalId="2e_rZByaj3v9TmNwzXRpFy"
The GUID of the dictionary can be stored directly in this attribute.
Some elements in IFC do not provide the attribute "GlobalId". These are for instance:
IfcClassificationReference IfcLabel-wrapper
To store the information about the link to the dictionary, we can insert a mapping table in the file, that maps the internal ID's to the GUID's for those elements that not provide a "GlobalId"
