Grove schemas (property sets) can also be automatically
translated/compiled to provide interface declarations in any language.
We do this at TechnoTeacher to create documentation-compatible
interfaces to groves stored in different ODBMSs, as well as to be able
to provide access to those groves from different languages and
environments. IDL, Java, and C++ can all be generated easily from the
same property set.
It is not necessary that developers using these APIs (in IDL, Java,
C++, etc.) know about groves or property sets. However, if there is
one canonical form of the API (the property set), a developer that
learned his way around the API in C++ will not be confused if he is
subsequently required to use the API in Java, Scheme, SQL, etc.
