Means for the exchange of Topic Maps are crucial for their further development of Topic Maps as industry integration standard. All existing approaches base on shared vocabularies. We clarify the term "absence of shared vocabularies" in the context of Topic Map Exchange. Afterwards we introduce the existing approaches for Topic Map Exchange and emphasise their limitations in the absence of shared vocabularies. Afterwards the SIM Approach is introduced and discussed. The SIM Approach allows the exchange of Topic Maps in the absence of shared vocabularies.

8. Possible Subject Equality Approaches of a SMD Referential Subject Equality Approach [A reference to a discrete ‘object’ indicates the intended Subject.] - Subject Proxy 1 indicates its Subject by pointing to it with S1 - Subject Proxy 2 indicates its Subject by pointing to it with S2 - Subject Equality holds if S1=S2 Structuralist Subject Equality Approach [The Subject depends on other Subject Proxies of the Subject Map.] - Subject Proxy 1 indicates its Subject through a set of Subject Proxies s1 - Subject Proxy 2 indicates its Subject through a set of Subject Proxies s2 - Subject Equality holds if s1 = s2 (or S1 similar S2) Meaning (semantics) in linguistics referential semantics The meaning of word is defined by the object it refers to. structuralist semantics The meaning of a word is defined by its usage in the language. The different Approaches to Subject Equality define the semantics of the used vocabulary at the time of the Subject Equality Decision.
